We believe private communication is a fundamental human right. This policy explains how bitchat protects your privacy. +bitchat is designed for private, account-free communication. This policy describes what the app keeps on your device, what it sends when you use mesh or optional internet features, and how long local data can remain. ## Summary -- **No personal data collection** - We don't collect names, emails, or phone numbers -- **No servers** - Everything happens on your device and through peer-to-peer connections -- **No tracking** - We have no analytics, telemetry, or user tracking -- **Open source** - You can verify these claims by reading our code +- **No project-operated accounts or messaging servers** — Bluetooth mesh is peer-to-peer; optional internet features use public or user-selected Nostr relays. +- **No analytics, advertising, telemetry, or tracking** — the app does not contain an analytics or advertising SDK. +- **No sale of data** — the project does not sell user data or build advertising profiles. +- **Open source** — the storage, networking, and cryptography described here can be inspected in the source code. -## What Information bitchat Stores +## What bitchat Stores on Your Device -### On Your Device Only +1. **Identity and cryptographic keys** + - Noise, signing, group, prekey, and optional Nostr identity material is generated locally. + - Secret keys are stored in the system keychain as device-only items. Public keys are shared when required for messaging, verification, groups, or Nostr events. + - Keys remain until they are rotated, removed by the relevant feature, or erased with panic wipe. Because operating-system keychains can outlive an uninstall, bitchat records a non-secret install marker and deletes surviving app keys before use after a later reinstall. -1. **Identity Key** - - A cryptographic key generated on first launch - - Stored locally in your device's secure storage - - Allows you to maintain "favorite" relationships across app restarts - - Never leaves your device +2. **Nickname, preferences, and relationships** + - Your nickname, settings, favorites, petnames, read-receipt identifiers, and bounded operational metadata are stored locally. + - The share extension can retain one item you choose to share in the app-group preferences for up to 24 hours. The app shows the destination and a preview for review; it does not send the item automatically. The item is cleared when you add it to the composer, cancel, panic-wipe, or it expires. -2. **Nickname** - - The display name you choose (or auto-generated) - - Stored only on your device - - Shared with peers you communicate with +3. **Private group state** + - Group names, rosters, creator identity, and key epoch are stored as protected files in Application Support. + - Current group keys are stored in the keychain. Group state remains until you leave or remove the group, panic-wipe the app, or remove the app. -3. **Message History** (if enabled) - - When room owners enable retention, messages are saved locally - - Stored encrypted on your device - - You can delete this at any time +4. **Queued and carried private messages** + - An outgoing private message that has not been acknowledged may remain for up to 24 hours in a bounded, encrypted outbox. The outbox is sealed with ChaCha20-Poly1305 and its key is stored in the keychain. + - A device acting as a courier may store a bounded opaque end-to-end encrypted envelope for another user for up to 24 hours.

This whitepaper details the BitChat Protocol Stack, a layered architecture that combines a modern cryptographic foundation with a flexible application protocol. At its core, BitChat leverages the Noise Protocol Framework (specifically, the `XX` pattern) to establish mutually authenticated, end-to-end encrypted sessions between peers. This document provides a technical specification of the identity management, session lifecycle, message framing, and security considerations that underpin the BitChat network. +bitchat is a decentralized, peer-to-peer messaging application for secure, private, censorship-resistant communication that works with or without the internet. Nearby devices form an ad-hoc Bluetooth Low Energy (BLE) mesh; distant peers are reached over the Nostr protocol when a connection exists. A layered store-and-forward stack — a persistent sender outbox, opportunistic couriers with a spray-and-wait copy budget, gossip-synced public history, and Nostr relay mailboxes — delivers messages to peers who are out of range at send time. This document describes the protocol and its delivery guarantees as implemented. --- -## 1. Introduction +## 1. Design Goals -In an era of centralized communication platforms, BitChat offers a resilient alternative by operating without central servers. It is designed for scenarios where internet connectivity is unavailable or untrustworthy, such as protests, natural disasters, or remote areas. Communication occurs directly between devices over transports like Bluetooth Low Energy (BLE). +* **Confidentiality:** all private communication is end-to-end encrypted; intermediate nodes and couriers carry only opaque ciphertext. +* **Authentication:** peers are identified by cryptographic keys; announcements are signed and verified. +* **Resilience:** the network functions in lossy, low-bandwidth, partitioned environments with churning membership. +* **Eventual delivery:** a message to an out-of-range peer should still arrive — relayed by the mesh, carried by a moving person, or resting on an internet relay — within a bounded retention window. +* **Ephemerality by default:** conversation timelines live in memory only. Everything the store-and-forward stack persists is either sealed ciphertext or already-public broadcast traffic, and all of it dies with the panic wipe. Media is the exception: accepted images and voice notes are written to disk unsealed, protected by the platform's data-protection class rather than by app-layer encryption, and bounded by a storage quota. -The design goals of the BitChat Protocol are: +## 2. Architecture Overview -* **Confidentiality:** All communication must be unreadable to third parties. -* **Authentication:** Users must be able to verify the identity of their correspondents. -* **Integrity:** Messages cannot be tampered with in transit. -* **Forward Secrecy:** The compromise of long-term identity keys must not compromise past session keys. -* **Deniability:** It should be difficult to cryptographically prove that a specific user sent a particular message. -* **Resilience:** The protocol must function reliably in lossy, low-bandwidth environments. +Two transports implement a common `Transport` interface and are coordinated by a `MessageRouter`: -This paper specifies the technical details of the protocol designed to meet these goals. +* **BLE mesh** — every device is simultaneously a GATT central and peripheral, relaying packets in a controlled flood. No infrastructure, pairing, or accounts. +* **Nostr** — private messages to mutual favorites travel in BitChat's app-specific encrypted envelopes over public relays (over Tor where enabled), bridging separate meshes through the internet. ---- +The router prefers a live mesh link, falls back to Nostr, and engages the courier system when neither can deliver promptly. -## 2. Protocol Stack +## 3. Identity -The BitChat Protocol is a four-layer stack. This layered approach separates concerns, allowing for modularity and future extensibility. +Each device holds two long-term key pairs in the Keychain: -```mermaid -graph TD - A[Application Layer] --> B[Session Layer]; - B --> C[Encryption Layer]; - C --> D[Transport Layer]; +* a **Curve25519 static key** for Noise key agreement — its SHA-256 fingerprint is the peer's stable identity, and +* an **Ed25519 signing key** for packet signatures. - subgraph "BitChat Application" - A - end +On the mesh, peers appear under a short 8-byte peer ID. That ID is **not ephemeral**: it is the first 8 bytes of the SHA-256 fingerprint of the device's Noise static key, so it is stable across sessions, reboots, and reinstalls that preserve the keychain, and it changes only when the identity itself is replaced by a panic wipe. Favoriting pins the full Noise public key so identity survives across sessions. Mutual favorites also exchange Nostr public keys for the internet path. Optional QR verification binds a nickname to a fingerprint in person. - subgraph "Message Framing & State" - B - end +Signed announcements additionally carry the nickname, the Noise static public key, and the Ed25519 signing public key in cleartext (§4.5), so a passive receiver in radio range can link a device across time and place regardless of the peer ID. Unlinkable presence is not a property this protocol currently provides; see §9. - subgraph "Noise Protocol Framework" - C - end +## 4. BLE Mesh Layer - subgraph "BLE, Wi-Fi Direct, etc." - D - end +### 4.1 Packet Format - style A fill:#cde4ff - style B fill:#b5d8ff - style C fill:#9ac2ff - style D fill:#7eadff -``` +A compact binary header (version, type, TTL, timestamp, flags) is followed by an 8-byte sender ID, an optional 8-byte recipient ID, the payload, and an optional Ed25519 signature. Version 2 packets may carry an explicit source route. Signatures exclude the TTL byte so relays can decrement it without invalidating them. -* **Application Layer:** Defines the structure of user-facing messages (`BitchatMessage`), acknowledgments (`DeliveryAck`), and other application-level data. -* **Session Layer:** Manages the overall communication packet (`BitchatPacket`). This includes routing information (TTL), message typing, fragmentation, and serialization into a compact binary format. -* **Encryption Layer:** Establishes and manages secure channels using the Noise Protocol Framework. It is responsible for the cryptographic handshake, session management, and transport message encryption/decryption. -* **Transport Layer:** The underlying physical medium used for data transmission, such as Bluetooth Low Energy (BLE). This layer is abstracted away from the core protocol. +Only `noiseEncrypted` and `noiseHandshake` packets are padded, toward 256/512/1024/2048-byte buckets; every other type — public messages, announcements, board posts, group messages, fragments, files, and voice frames — goes out at its natural length. Padding is PKCS#7-style with pad bytes equal to the pad length, and because that length must fit one byte, a frame needing more than 255 bytes to reach its bucket is emitted unpadded. Payload length is therefore observable for most traffic. ---- +### 4.2 Flood Control -## 3. Identity and Key Management +Relaying is a deterministic controlled flood tuned by local connection degree: -A peer's identity in BitChat is defined by two persistent cryptographic key pairs, which are generated on first launch and stored securely in the device's Keychain. +* **TTL:** packets originate with TTL 7. Relays clamp: dense graphs (≥ 6 links) cap broadcast TTL at 5; thin chains (≤ 2 links) relay at full incoming depth. +* **Deduplication:** an LRU seen-set (1000 entries, 5-minute expiry) keyed by sender, timestamp, type, and a payload digest drops duplicates. A scheduled relay is cancelled when a duplicate arrives first from another relay. +* **Jitter:** relays wait a random 10–220 ms (wider when dense) so duplicate suppression wins often. +* **Fanout subsetting:** broadcast messages are re-sent to a deterministic, message-ID-seeded subset of links (~log₂ of degree) rather than all of them; announces, fragments, and sync packets use full fanout. The ingress link is always excluded (split horizon). +* **Directed traffic** (handshakes, private messages, courier envelopes) relays deterministically with TTL − 1 and tight jitter, and is never subset. -1. **Noise Static Key Pair (`Curve25519`):** This is the long-term identity key used for the Noise Protocol handshake. The public part of this key is shared with peers to establish secure sessions. -2. **Signing Key Pair (`Ed25519`):** This key is used to sign announcements and other protocol messages where non-repudiation is required, such as binding a public key to a nickname. +### 4.3 Routing -### 3.1. Fingerprint +Announcements carry up to 10 direct-neighbor IDs, giving each node a shallow topology map (60 s freshness). When a bidirectionally-confirmed path exists, packets are source-routed along it; otherwise — and whenever a route fails — delivery falls back to flooding. -A user's unique, verifiable fingerprint is the **SHA-256 hash** of their **Noise static public key**. This provides a user-friendly and secure way to verify an identity out-of-band (e.g., by reading it aloud or scanning a QR code). +### 4.4 Fragmentation -`Fingerprint = SHA256(StaticPublicKey_Curve25519)` +Packets exceeding the link MTU split into ~469-byte fragments (8-byte fragment ID, index/total header) that relay independently and reassemble at each receiving node (128 concurrent assemblies, 30 s timeout, 1 MiB cap). -### 3.2. Identity Management +### 4.5 Presence -The `SecureIdentityStateManager` class is responsible for managing all cryptographic identity material and social metadata (petnames, trust levels, etc.). It uses an in-memory cache for performance and persists this cache to the Keychain after encrypting it with a separate AES-GCM key. +Signed announcements propagate multi-hop: every 4 s while isolated, backing off to ~15–30 s (jittered) when connected. A verified announce retains a peer as *reachable* for 60 s after last contact. Connection scheduling is RSSI-gated with duty-cycled scanning to bound battery drain. ---- +## 5. Encryption -## 4. The Social Trust Layer +### 5.1 Live Sessions: Noise XX -Beyond cryptographic identity, BitChat incorporates a social trust layer, allowing users to manage their relationships with peers. This functionality is handled by the `SecureIdentityStateManager`. +Connected peers establish sessions with the Noise `XX` pattern (Curve25519 / ChaCha20-Poly1305 / SHA-256), providing mutual authentication and forward secrecy. All private payloads — messages, delivery acks, read receipts — ride inside the session as typed ciphertext. Intermediate relays see only opaque `noiseEncrypted` packets. -### 4.1. Peer Verification +### 5.2 Offline Seals: Noise X -While the Noise handshake cryptographically authenticates a peer's key, it doesn't confirm the real-world identity of the person holding the device. To solve this, users can perform out-of-band (OOB) verification by comparing fingerprints. Once a user confirms that a peer's fingerprint matches the one they expect, they can mark that peer as "verified". This status is stored locally and displayed in the UI, providing a strong assurance of identity for future conversations. +Courier envelopes are sealed to the recipient's *static* key with the one-way Noise `X` pattern; the sender's identity is authenticated inside the ciphertext. **This path has no forward secrecy** — compromise of the recipient's static key exposes sealed-but-undelivered mail. A prekey scheme is future work. -### 4.2. Favorites and Blocking +### 5.3 Nostr Path -To improve the user experience and provide control over interactions, the protocol supports: -* **Favorites:** Users can mark trusted or frequently contacted peers as "favorites". This is a local designation that can be used by the application to prioritize notifications or display peers more prominently. -* **Blocking:** Users can block peers. When a peer is blocked, the application will discard any incoming packets from that peer's fingerprint at the earliest possible stage, effectively silencing them without notifying the blocked peer. +Private messages to mutual favorites use BitChat's proprietary private-envelope protocol. An unsigned inner message (kind 14) is encrypted and placed in a sender-signed seal (kind 13); that seal is encrypted again inside a public envelope (kind 1059) signed by a one-time key, so relays learn neither the stable sender identity nor the content. Each encrypted content field is `v2:` followed by base64url of a 24-byte nonce, XChaCha20-Poly1305 ciphertext, and its 16-byte tag. Keys come from secp256k1 ECDH and HKDF-SHA256 (the derivation reuses a "nip44-v2" info label but is not the NIP-44 key schedule). ---- +This format reuses NIP-17/NIP-59 kind numbers but is **not NIP-17, NIP-44, or NIP-59 compatible** and interoperates only with BitChat clients. The outer `p` tag exposes the recipient's Nostr public key to relays; the plaintext and stable sender identity remain inside authenticated ciphertext. Public seal and envelope timestamps are randomized by up to ±15 minutes, while the actual message timestamp is encrypted. The protocol does not provide forward secrecy: compromise of the recipient's static Nostr private key can expose stored envelopes addressed to that key. -## 5. The Noise Protocol Layer +## 6. Store and Forward -BitChat implements the Noise Protocol Framework to provide strong, authenticated end-to-end encryption. +Four mechanisms cover the "recipient is not here right now" problem. All persisted state is wiped by panic mode. -### 5.1. Protocol Name +### 6.1 Sender Outbox -The specific Noise protocol implemented is: +Private messages without a prompt route are retained per peer (100 messages/peer, 24 h TTL) and re-sent on reconnect events until a delivery or read ack clears them, or a resend cap (8 attempts) drops them with visible failure. The outbox persists to disk sealed under a ChaChaPoly key held only in the Keychain, so queued mail survives an app kill without ever storing plaintext. -**`Noise_XX_25519_ChaChaPoly_SHA256`** +### 6.2 Couriers -* **`XX` Pattern:** This handshake pattern provides mutual authentication and forward secrecy. It does not require either party to know the other's static public key before the handshake begins. The keys are exchanged and authenticated during the three-part handshake. This is ideal for a decentralized P2P environment. -* **`25519`:** The Diffie-Hellman function used is Curve25519. -* **`ChaChaPoly`:** The AEAD (Authenticated Encryption with Associated Data) cipher is ChaCha20-Poly1305. -* **`SHA256`:** The hash function used for all cryptographic hashing operations is SHA-256. +When no transport can deliver promptly, the message is sealed (§5.2) into a **courier envelope** and handed to up to 3 connected peers who may physically encounter the recipient: -### 5.2. The `XX` Handshake +* **Opaque addressing.** The only routing information is a 16-byte rotating recipient tag — an HMAC of the recipient's static key and the UTC day — computable solely by parties who already know that key. Couriers learn neither sender, recipient, nor content, and tags do not correlate across days. +* **Trust tiers.** Mutual favorites may deposit 5 envelopes each; any peer with a signature-verified announce may deposit 2, into a bounded pool (20 of 40 slots) that can never crowd out favorites' mail. Envelopes are capped at 16 KiB and 24 h; overflow evicts oldest verified-tier mail first. +* **Deposit retry.** Queued messages are re-deposited whenever a new eligible courier connects, until 3 distinct couriers carry the message or it expires. +* **Spray and wait.** Envelopes carry a copy budget (initially 4, capped at 8). A courier meeting another eligible courier hands over half its remaining budget, so mail diffuses through a moving crowd instead of riding one person. Budgets, spray history, and carried mail persist across app restarts (iOS file protection). +* **Handover.** On a verified *direct* announce from the recipient, matching envelopes are delivered over the live link and removed. On a verified *relayed* announce, a copy floods toward the recipient as a directed packet while the carried original stays put, throttled to one attempt per envelope per 10 minutes. +* Receivers dedup by message ID, so redundant copies and the retained outbox original are harmless. Couriered mail from blocked senders is dropped at decryption time. -The `XX` handshake consists of three messages exchanged between an Initiator and a Responder to establish a shared secret and derive transport encryption keys. +### 6.3 Public History (Gossip Sync) -```mermaid -sequenceDiagram - participant I as Initiator - participant R as Responder +Public broadcast messages are cached (1000 packets) and reconciled between peers every ~15 s using compact GCS filters: each side advertises what it holds, the other returns what is missing.

Application Layer -**Handshake Flow:** - -1. **Initiator -> Responder:** The initiator generates a new ephemeral key pair (`e_i`) and sends the public part to the responder. -2. **Responder -> Initiator:** The responder receives the initiator's ephemeral public key. It then generates its own ephemeral key pair (`e_r`), performs a DH exchange with the initiator's ephemeral key (`ee`), sends its own static public key (`s_r`) encrypted with the resulting symmetric key, and performs another DH exchange between the initiator's ephemeral key and its own static key (`es`). -3. **Initiator -> Responder:** The initiator receives the responder's message, decrypts the responder's static key, and authenticates it. The initiator then sends its own static key (`s_i`) encrypted and performs a final DH exchange between its static key and the responder's ephemeral key (`se`). - -Upon completion, both parties share a set of symmetric keys for bidirectional transport message encryption. The final handshake hash is used for channel binding. - -### 5.3. Session Management - -The `NoiseSessionManager` class manages all active Noise sessions. It handles: -* Creating sessions for new peers. -* Coordinating the handshake process to prevent race conditions. -* Storing the resulting transport ciphers (`sendCipher`, `receiveCipher`). -* Periodically checking if sessions need to be re-keyed for enhanced security. - ---- - -## 6.

Message Routing and Propagation - -BitChat operates as a decentralized mesh network, meaning there are no central servers to route messages. Packets are propagated through the network from peer to peer. The protocol supports several modes of message delivery. - -### 7.1. Direct Connection - -This is the simplest case. If Peer A and Peer B are directly connected, they can exchange packets after establishing a mutually authenticated Noise session. All packets are encrypted using the transport ciphers derived from the handshake. - -### 7.2. Efficient Gossip with Bloom Filters - -To send messages to peers that are not directly connected, BitChat employs a "flooding" or "gossip" protocol. When a peer receives a packet that is not destined for it, it acts as a relay. To prevent infinite routing loops and minimize memory usage, the protocol uses an `OptimizedBloomFilter` to track recently seen packet IDs. - -The logic is as follows: - -1. A peer receives a packet. -2. It checks the Bloom filter to see if the packet's ID has likely been seen before. If so, the packet is discarded. Bloom filters can have false positives (though they are rare), but they guarantee no false negatives. This means that while some packets may be incorrectly discarded due to false positives, the gossip protocol's redundancy ensures these packets will eventually be received through subsequent exchanges with other peers. -3. If the packet is new, its ID is added to the Bloom filter. -4. The peer decrements the packet's Time-To-Live (TTL) field. -5. If the TTL is greater than zero, the peer re-broadcasts the packet to all of its connected peers, *except* for the peer from which it received the packet. - -This mechanism allows packets to "flood" through the network efficiently, maximizing the chance of reaching their destination while using minimal resources to prevent loops. - -### 7.3. Time-To-Live (TTL) - -Every `BitchatPacket` contains an 8-bit TTL field. This value is set by the originating peer and is decremented by one at each relay hop. If a peer receives a packet and decrements its TTL to 0, it will process the packet (if it is the recipient) but will not relay it further. This is a crucial mechanism to prevent packets from circulating endlessly in the mesh. - -### 7.4. Private vs. Broadcast Messages - -The routing logic respects the confidentiality of private messages: - -* **Private Messages:** A packet with a specific `recipientID` is a private message. Relay nodes forward the entire, encrypted Noise message without being able to access the inner `BitchatPacket` or its payload. Only the final recipient, who shares the correct Noise session keys with the sender, can decrypt the packet. -* **Broadcast Messages:** A packet with the special broadcast `recipientID` (`0xFFFFFFFFFFFFFFFF`) is intended for all peers. Any peer that receives and decrypts a broadcast message will process its content. It will still be relayed according to the flooding algorithm to ensure it reaches the entire network. - -### 7.5. Message Reliability and Lifecycle - -To function in unreliable, lossy networks, the protocol includes features to track the lifecycle of a message and ensure its delivery. - -* **Delivery Acknowledgments (`DeliveryAck`):** When a private message reaches its final destination, the recipient's device sends a `DeliveryAck` packet back to the original sender. This acknowledgment contains the ID of the original message. -* **Read Receipts (`ReadReceipt`):** After a message is displayed on the recipient's screen, the application can send a `ReadReceipt`, also containing the original message ID, to inform the sender that the message has been seen. -* **Message Retry Service:** Senders maintain a `MessageRetryService` which tracks outgoing messages. If a `DeliveryAck` is not received for a message within a certain time window, the service will automatically re-send the message, creating a more resilient user experience. - -### 7.6. Fragmentation - -Transport layers like BLE have a Maximum Transmission Unit (MTU) that limits the size of a single packet. To handle messages larger than this limit, BitChat implements a fragmentation protocol. - -* **`fragmentStart`:** A packet with this type marks the beginning of a fragmented message. It contains metadata about the total size and number of fragments. -* **`fragmentContinue`:** These packets carry the intermediate chunks of the message data. -* **`fragmentEnd`:** This packet carries the final chunk of the message and signals the receiver to begin reassembly. - -Receiving peers collect all fragments and reassemble them in the correct order before passing the complete message up to the application layer. - ---- +* **Public chat** — signed broadcast messages within the mesh, backed by the gossip-synced history above. +* **Private chat** — end-to-end encrypted messages with delivery and read receipts, over mesh, courier, or Nostr. +* **Location channels** — geohash-scoped public rooms carried over Nostr relays for regional chat beyond radio range. +* **Favorites** — the mutual-trust relationship that unlocks Nostr delivery and the larger courier quota. +* **Media** — files and images fragment over the mesh (1 MiB cap, explicit accept before anything touches disk); couriers carry text only. +* **Panic wipe** — clears identity keys, favorites, carried courier mail, the sealed outbox, archived public history, and metrics. ## 8. Security Considerations -* **Replay Attacks:** The Noise transport messages include a nonce that is incremented for each message. The `NoiseCipherState` implements a sliding window replay protection mechanism to detect and discard replayed or out-of-order messages. -* **Denial of Service:** The `NoiseRateLimiter` is implemented to prevent resource exhaustion from rapid, repeated handshake attempts from a single peer. -* **Key-Compromise Impersonation:** The `XX` pattern authenticates both parties, preventing an attacker from impersonating one party to the other. -* **Identity Binding:** While the Noise handshake authenticates the cryptographic keys, binding those keys to a human-readable nickname is handled at the application layer. Users must verify fingerprints out-of-band to prevent man-in-the-middle attacks. -* **Traffic Analysis:** The use of fixed-size padding for all packets helps to obscure the exact nature and content of the communication, making it harder for a network-level adversary to infer information based on message size. +* **Relay nodes** cannot read private traffic; they forward opaque ciphertext. Padding applies to Noise frames only (§4.1), so other packet types relay at their natural length. +* **Couriers** are quota-bounded mailbags. A malicious courier can drop mail (redundant copies and deposit retry mitigate this) but cannot read it, link it across days, or amplify it — copy budgets are capped and every envelope is validated against size and lifetime policy on deposit. +* **Flooding abuse** is bounded by TTL clamps, deduplication, per-depositor quotas, connect-rate limits, and announce-rate limiting. +* **Replay** of public broadcasts is bounded by the 6-hour acceptance window plus deduplication; private payloads are protected by Noise nonces. +* **Metadata is the weakest part of this design, and the peer ID does not help.** The 8-byte sender ID in every packet header is derived from a never-rotating key (§3), and announcements publish the static keys and nickname in cleartext, so a passive listener can enumerate participants and follow a device between places. Announcements also carry up to ten direct-neighbor IDs (§4.3), which hands a single sniffer the local adjacency graph. Origin packets leave at the default TTL, so hop distance identifies the originator. Daily-rotating courier tags do limit correlation of carried mail, and Nostr traffic can ride Tor. Addressing the radio-layer exposure is future work (§9). +* **No forward secrecy for sealed mail or Nostr private envelopes** (§5.2–5.3) means compromise of a recipient's static key can expose retained ciphertext addressed to that key. + +## 9. Future Work + +* Prekey-based forward secrecy for courier envelopes. +* Couriered media beyond the 16 KiB text cap. +* Probabilistic relay and edge-of-network TTL boosting for very dense and very sparse graphs. +* Multi-hop courier routing informed by encounter history. +* **Rotating on-air identity.** Epoch-rotating peer IDs, with static-key disclosure moved inside the encrypted handshake and mutual favorites recognising each other through a tag derived from their shared secret, so presence stops being linkable across sessions (§3, §8). +* **Padding for non-Noise packet types**, and closing the gap where a frame needing more than 255 bytes of padding is emitted unpadded (§4.1). +* Making the neighbor list in announcements optional, or restricted to authenticated links (§4.3). --- -## 9. Conclusion - -The BitChat Protocol provides a robust and secure foundation for decentralized, peer-to-peer communication. By layering a flexible application protocol on top of the well-regarded Noise Protocol Framework, it achieves strong confidentiality, authentication, and forward secrecy. The use of a compact binary format and thoughtful security considerations like rate limiting and traffic analysis resistance make it suitable for use in challenging network environments. +*This document describes the protocol as implemented in the current release.

Mesh-level propagation of the +/// original broadcast packet is the TTL relay's job, not ours. +/// 2.

transport and protocol stack in one pass. + +## What Landed + +1. `AppRuntime` is now the composition root for startup, lifecycle, notification routing, and shared-content intake. +2. `BitchatApp` is reduced to app wiring and no longer owns operational startup logic. +3. `AppEventStream` introduces a typed async event surface for app-level events. +4. `PeerHandle` and `ConversationID` establish canonical identity/conversation keys above the existing transport-specific IDs. +5. `IdentityResolver` mirrors the current peer graph into canonical handles. +6. `ConversationStore` now owns app-layer conversation context for the active public channel and selected private conversation, while also mirroring the current public/private message timelines under canonical IDs. +7. `AppRuntime` now owns Tor, screenshot, and Nostr reconnect observer wiring instead of leaving that app-lifecycle graph inside `ChatViewModel`. +8. `PublicChatModel`, `PrivateInboxModel`, `PrivateConversationModel`, `ConversationUIModel`, `LocationChannelsModel`, and `PeerListModel` provide focused view-facing models for public chat, private inbox state, selected-DM state, composer/message interactions, location-channel state, and peer counts. `PrivateInboxModel` now reads its message, unread, and selection state directly from `ConversationStore` instead of merging through `PrivateChatManager`. +9. `AppChromeModel` now owns app-chrome presentation state for nickname editing, fingerprint routing, app-info/location sheet visibility, unread-private-chat affordances, and screenshot/privacy UI. +10. `ContentView`, `MessageListView`, `LocationChannelsSheet`, `LocationNotesView`, `CommandSuggestionsView`, `FingerprintView`, and `VerificationSheetView` no longer talk directly to `ChatViewModel` or location singletons for their primary app-layer state; they consume feature-scoped models injected from `AppRuntime`. +11. `PeerListModel` now consumes the runtime-owned `LocationChannelsModel` instead of reading the location manager directly, and QR scan parsing is funneled through `VerificationModel` rather than the SwiftUI views. +12. `ChatViewModel` is thinner on the app side: startup wiring now lives in `ChatViewModelBootstrapper`, send/lifecycle/transport seams live in focused coordinators, and peer-list notification/timer state now lives in `ChatPeerListCoordinator` instead of the main view model. + +## Why This Shape + +- `ChatViewModel` remains the active domain/UI bridge so the app can keep working while we migrate feature-by-feature. +- The new runtime/store layer gives us a safe place to move lifecycle, routing, and cross-cutting state before we split the UI into smaller feature models. +- `ConversationStore` now owns the selected conversation context and private-inbox read state, which lets feature models read one runtime-managed source of truth for focus/navigation and DM timelines even while legacy mutation paths still flow through `ChatViewModel`. +- The new chrome model lets us remove presentation-only state from `ChatViewModel` without forcing a big rewrite of the domain/message paths. +- The private-conversation model pulls selected-DM header identity, availability, encryption, and favorite state out of `ContentView`, which keeps the view from re-implementing peer lookup rules. +- The conversation UI model centralizes composer state, autocomplete, message formatting, and row-level actions so the main views no longer proxy most conversation interactions directly to `ChatViewModel`. +- The location channels model gives the remaining location-heavy views a focused adapter over the location/bookmark/network singletons, which reduces direct global reads in the view layer and makes smoke/architecture tests more reliable. +- Reusing that same location model inside the peer-list feature keeps geohash/mesh presence presentation on one runtime-owned source of truth instead of mixing view models with singleton reads. +- `BitchatApp` now injects only feature-scoped models into the view tree, which removes the old pattern of keeping `ChatViewModel` as a global environment object for the entire app shell. +- Routing QR scan parsing through the verification model keeps the verification UI as a passive renderer and gives us a clearer seam for future camera/manual-scan behavior changes. +- The new `ChatViewModel` coordinators are intentionally transitional: they shrink the main file and isolate composition, lifecycle, transport, and peer-list responsibilities without forcing a risky rewrite of the transport/BLE core in the same pass. + +## Next Steps + +1. Migrate view composition from one global `ChatViewModel` to focused feature models backed by `ConversationStore`. +2. Route more inbound transport events through typed app/domain events instead of delegate plus notification fan-out. +3. Move private/public conversation mutation behind the new store instead of still mirroring legacy message writes from `ChatViewModel`. +4. Replace remaining singleton-heavy seams with injected runtime services where practical. +5. Revisit actor isolation for identity and conversation state once the remaining message/peer models are safe to move off the main actor. + +## Transport Follow-Up + +The Bluetooth architecture branch begins step 2 by adding a typed `TransportEvent` boundary while preserving the legacy `BitchatDelegate` bridge. New transport code should emit typed events first, with delegate forwarding used only as a compatibility adapter during migration. + +The branch also starts carving performance-sensitive BLE scheduling state out of `BLEService`: pending write backpressure now lives in `BLEOutboundWriteBuffer`, giving the outbound hot path a focused, unit-tested component before deeper fragmentation and link-scheduler work. + +The next transport slice continues that path by extracting ingress link memory and outbound fanout selection. `BLEIngressLinkRegistry` now owns duplicate/last-hop tracking, ingress peer memory, and direct-link sender binding decisions, while `BLEFanoutSelector` owns deterministic broadcast subsetting and ingress-peer/link exclusion. `BLEService` still coordinates CoreBluetooth callbacks, but these hot-path decisions are now pure, covered units instead of inline dictionary logic. diff --git a/docs/ARTI-BINARY-PROVENANCE.md b/docs/ARTI-BINARY-PROVENANCE.md new file mode 100644 index 00000000..9f44db3c --- /dev/null +++ b/docs/ARTI-BINARY-PROVENANCE.md @@ -0,0 +1,94 @@ +# Arti Binary Provenance + +This repo vendors a prebuilt Arti static-library xcframework at: + +`localPackages/Arti/Frameworks/arti.xcframework` + +SwiftPM links it through `localPackages/Arti/Package.swift` as the binary target named `arti`.

Sent as seq 0 and re-attached (piggybacked TLV) every ~2 s so mid-burst joiners can sync. +- `0x02 END` — payload: total data-packet count (UInt16), duration ms (UInt32). Lets receivers detect tail loss. +- `0x04 CANCELED` — sender slid-to-cancel; receivers stop playback, discard buffered audio, and drop the bubble. +- `0x00` (data) — payload is N length-prefixed AAC frames: `[len: UInt16 BE][ADTS-less raw AAC frame]…` + +Audio math: AAC-LC at 16 kHz has 1024-sample frames = **64 ms/frame ≈ 130 B at 16 kbps**. A greedy packetizer batches frames up to a **210-byte burst-content budget** (`pttMaxBurstContentBytes`), chosen so the Noise ciphertext (content + 1 inner-type byte + 16-byte tag) stays inside `MessagePadding`'s 256-byte bucket — the whole directed packet is 288 bytes and voice **never enters the fragment scheduler** (which caps concurrent transfers at 2 and would starve file sends). At 16 kbps that works out to **1 frame/packet, ~15.6 pkt/s, ~5.3 KB/s wire** for DMs; public bursts (unpadded, planned for phase 2) can batch 3 frames. + +### 3.2 Public mesh: new `MessageType.voiceFrame = 0x29` + +- Broadcast (no recipient), **signed** like public messages; unsigned or signature-mismatched frames are dropped on receive. +- **No padding** (add to `BLEOutboundPacketPolicy` alongside `fileTransfer`) — padding to the 512 block would push every packet over MTU into fragmentation. +- TTL: `messageTTL` (7) at origin; `RelayController` gets a `voiceFrame` case mirroring the fragment policy — dense clamp to 5, jitter 8–25 ms — so live audio floods like fragments, not like announces. Per-hop cost is ~10–40 ms; 3 hops stays comfortably inside the jitter buffer. +- Dedup: existing `MessageDeduplicator` (timestamp ms + seq make each packet unique). +- 0x29 is the next free code after `nostrCarrier = 0x28`; unknown types are ignored by older clients (iOS and Android), so rollout is compatible — old clients simply don't hear live bursts. + +### 3.3 DM: new `NoisePayloadType.voiceFrame = 0x08` + +- Inner payload = the same burst framing, wrapped in `noiseEncrypted` (0x11) directed packets — wire-indistinguishable from other DM traffic by size/type (0x04/0x05 are reserved per the comment in `BitchatProtocol.swift`; 0x08 is the first free slot after `groupKeyUpdate = 0x07`). +- Directed encrypted packets are already always-relayed by `RelayController`, so multi-hop DMs work unchanged. +- Requires an established session; PTT-live is only offered when `noiseService.hasEstablishedSession` (otherwise first hold triggers the normal handshake + falls back to voice-note for that burst). +- Fire-and-forget: **no delivery acks, no retransmit** for frames. Late audio is worthless; reliability comes from the finalized note (§5). + +### 3.4 Known traffic-analysis tradeoff + +A steady ~8 pkt/s cadence for the duration of a burst is a timing fingerprint even under Noise (observers can infer "someone is speaking to someone", not content). This is inherent to live voice; the doc records it as accepted for v1. Block padding is skipped for voiceFrame (size classes would leak little beyond what cadence already does). + +## 4. Sender pipeline + +`VoiceRecorder` (AVAudioRecorder → file) can't stream, so PTT capture uses a parallel path in a new `PTTStreamEncoder` actor: + +``` +AVAudioEngine input tap (native format) + → PTTInputResampler → 16 kHz mono PCM + → PTTFrameEncoder (AVAudioConverter) → AAC-LC frames → packetizer → BLEService.sendVoiceFrame + → the same PCM is simultaneously written to an AVAudioFile .m4a (identical settings + to VoiceRecorder), so finalization needs no remux step +``` + +- On release: emit `END`, then hand the finalized `.m4a` to the **existing** `sendVoiceNote` flow. The note's `fileName` embeds the burst ID (`voice_.m4a`) — that links note↔burst with **zero changes** to `BitchatFilePacket`/Android interop. +- On slide-to-cancel: stop tap, emit `CANCELED`, delete local file, skip finalization. UX note: unlike voice notes, live audio already played on the far side cannot be unsent — the recording UI must make "you are live" unmistakable (see §7). +- Caps: max burst 120 s (matching the voice-note recorder's cap), exactly one outbound burst at a time. +- Audio session: reuse `VoiceRecorder`'s `.playAndRecord` config; add `.duckOthers`. + +## 5. Receiver pipeline + +New `VoiceBurstAssembler` (keyed by sender + burstID) feeding a `PTTBurstPlayer`: + +- **Jitter buffer:** start playback after 350 ms of buffered audio or 500 ms wall-clock, whichever first. Frames decode via `AVAudioConverter` → `AVAudioPlayerNode`. +- **Loss handling:** gap in seq → insert silence for the missing frames (64 ms each) and keep going. No PLC in v1; at these frame sizes brief dropouts are acceptable. +- **Burst end:** on `END`, or 3 s with no frames (talker walked out of range). +- **Persistence:** frames append to an incoming ADTS `.aac` file (already an allowed `MimeType`), so every burst becomes a replayable voice-note bubble containing whatever was captured — even a partial one. +- **Dedup with the finalized note:** when a `fileTransfer` arrives whose fileName carries a burstID we already assembled (DM or public), it silently *replaces* the partial file behind the existing bubble (no new message row, no second notification). Receivers that heard everything live just get a lossless copy. +- **Resource caps:** ≤ 8 concurrent assemblies, ≤ 256 KB per burst (60 s × 2 KB/s + slack), 30 s stale cleanup, and drop inbound frames beyond ~2× realtime per sender (spam/flood guard). + +## 6. Playback policy — when does it actually make sound? + +Auto-playing strangers' audio is the fastest way to make this feature hated. Rules: + +1. **Live autoplay** only when *all* hold: app foregrounded, the burst's conversation is the one currently on screen, and the **"live voice messages"** toggle is on (app-level, in the app-info sheet, default on; per-conversation overrides are a v2 refinement). The same toggle gates live *sending* — off means voice behaves exactly like classic notes in both directions. +2. Otherwise the burst appears as a **live bubble**: pulsing waveform + `LIVE` badge + sender name; tapping it joins playback at the live edge. When the burst ends it becomes a normal voice-note bubble. +3. **One voice at a time:** route through `VoiceNotePlaybackCoordinator`. If two people talk simultaneously, the first burst holds the floor; the second shows as a tappable live bubble. No mixing in v1. +4. Notifications: a live burst in a non-focused DM fires the normal message notification once (at START), not per-frame. + +**Floor courtesy (public mesh):** while someone else's burst is live in the current channel, the mic button tints "busy" with the talker's name. Holding it still works — a decentralized mesh has no floor arbiter, and rejecting sends would desync under partitions — but the UI discourages talk-over. Hard floor control (token passing) is explicitly out of scope. + +## 7. UX + +- **Same gesture:** hold mic = talk. When the live path is active, the recording HUD shows a red pulsing **LIVE** treatment (vs. the current neutral recording UI) so the sender knows audio is leaving in real time, not on release. When live isn't available (Nostr-only peer, no session yet), the HUD looks like today's and behavior is unchanged. +- Slide-to-cancel keeps working in both modes, with the §4 caveat surfaced simply: cancel stops and discards; it can't unplay what was heard. +- VoiceOver: mirror the existing `accessibilityAction` toggle-record pattern on the mic button. +- Foreground-only in v1: no `audio` UIBackgroundMode (App Store review + battery implications). If the app backgrounds mid-burst, capture stops cleanly with END. Background listen/talk is a v2 candidate. + +## 8.

Investigate before building. + +That check alone is not enough. `shasum -c` verifies the files the manifest lists and says nothing about files it does not list — and the Xcode project compiles every source file present in the tree automatically, so a hostile mirror can pass the hash check by leaving every listed file intact and *adding* one. Confirm nothing extra is present: + +```sh +# The manifest's path list must match the tree exactly — no missing files, no extras +grep -v '^#' /tmp/SOURCE-MANIFEST.txt | sed 's/^[0-9a-f]* //' | LC_ALL=C sort > /tmp/manifest-paths +find . -type f ! -path './.git/*' | sed 's|^\./||' | LC_ALL=C sort > /tmp/actual-paths +diff /tmp/manifest-paths /tmp/actual-paths # must print nothing +``` + +In a git checkout the same assurance is one command — it also catches extra files, because they show as untracked. `--ignored` matters: `.gitignore` covers paths like `build/`, plain `git status` would not report a planted file there, and Xcode compiles it all the same: + +```sh +git status --porcelain --ignored # must print nothing before you build +``` + +The single value that covers the whole tree is the git tree hash in the manifest header: + +```sh +git rev-parse HEAD^{tree} # must equal the "tree:" line in the manifest +``` + +Note the tree hash covers tracked content only; it does not see untracked files sitting in the working directory, which is why the emptiness checks above come first. + +The manifest itself carries a provenance attestation tying it to the workflow run that produced it, so a manifest handed to you along with a mirror is checkable too: + +```sh +gh attestation verify /tmp/SOURCE-MANIFEST.txt --repo permissionlesstech/bitchat +``` + +That last step is what makes this resistant to a hostile mirror. Without it, whoever gives you the source can give you a matching manifest. + +### If the manifest is unavailable + +Compare against a commit instead. Git object hashes cover content and history, so if you can obtain the expected commit hash through any channel you trust — a second mirror, a maintainer's post elsewhere, someone who cloned earlier — then: + +```sh +git fetch --tags +git rev-parse v1.2.3 # compare against the hash you trust +git verify-tag v1.2.3 # if the tag is signed +``` + +A mirror whose history matches a commit hash you trust from elsewhere is a faithful mirror. + +## Builds from other sources + +If you have an `.ipa`, an `.apk`, or a Mac app from a forum, a chat group, a file locker, or any mirror, you cannot verify it, and this project cannot help you verify it. There is no published signing key for compiled builds and no reproducible-build pipeline, so there is nothing to compare a binary against. + +What to do instead, in order of preference: install from the App Store; build from verified source; or, if neither is possible, treat that build as untrusted — assume anything you type into it may be disclosed, do not use it for anything sensitive, and do not carry it somewhere it being on your phone is itself a risk. + +Do not rely on the app looking right. A modified build has no reason to look different. + +## For maintainers + +Cutting a release: + +- Push the tag. `source-manifest.yml` runs and attaches `SOURCE-MANIFEST.txt` to the release; if the release does not exist yet, collect the manifest from the workflow artifact and attach it when you publish. +- Sign the tag (`git tag -s`). A signed tag lets anyone verify the release came from a key you control, independent of GitHub. This needs a published key fingerprint to be useful — see the gap below. +- Note the commit hash somewhere outside this repository. If the repository is taken down, a hash recorded elsewhere is what lets people verify a mirror. + +Known gaps, so nobody assumes more protection than exists: + +- **No published signing key.** Tags are not currently verifiable against a known key. Publishing a fingerprint through channels independent of GitHub, and signing tags with it from then on, is the missing piece. +- **No verifiable compiled builds outside the App Store.** Closing this needs either a signed-and-notarized release pipeline or a reproducible build, and until one exists the guidance above stands. +- **No non-GitHub source mirror.** Every remote for this project is on the platform the takedown demands were served to. A mirror on independent infrastructure, published before it is needed, would mean a takedown does not remove the ability to verify. diff --git a/docs/privacy-assessment.md b/docs/privacy-assessment.md index cba3aa2e..92598407 100644 --- a/docs/privacy-assessment.md +++ b/docs/privacy-assessment.md @@ -1,64 +1,121 @@ -BitChat Privacy Assessment -========================== +# bitchat Privacy Assessment -Scope -- Mesh transport (BLE) behavior and metadata minimization -- Nostr-based private message fallback (gift-wrapped, end-to-end encrypted) -- Read receipts and delivery acknowledgments -- Logging/telemetry posture and controls +Last reviewed: July 2026 -Summary -- No accounts, no servers for mesh; Nostr used only for mutual favorites, with end-to-end Noise encryption encapsulated in gift wraps. -- BLE announces contain only nickname and Noise pubkey. No device name, no plaintext identity beyond what the user broadcasts. -- Discovery and flooding incorporate jitter and TTL caps to reduce linkability and propagation radius of encrypted payloads. -- UI and storage remain ephemeral; message content is not persisted to disk. Minimal state (e.g., read-receipt IDs) is stored for UX and is bounded/cleaned. -- Logging defaults to conservative levels; debug verbosity is suppressed for release builds. A single env var can raise/lower threshold when needed. +## Scope -BLE Privacy Considerations -- Announce content: Unchanged — nickname + Noise public key only. -- Local Name: Not used (explicitly disabled). Avoids leaking device/OS identity. -- Address: iOS uses BLE MAC randomization; BitChat does not attempt to set static addresses. -- Announce jitter: Each announce is delayed by a small random jitter to avoid synchronization-based correlation. -- Scanning: Foreground scanning uses “allow duplicates” briefly to improve discovery latency; background uses standard scanning parameters. -- RSSI gating: The acceptance threshold adapts to nearby density (approx. -95 to -80 dBm) to reduce long-distance observations in dense areas and improve connectivity in sparse ones. -- Fragmentation: Fragments use write-with-response for reliability (less re-broadcast churn = fewer repeated signals). -- GATT permissions: Private characteristic disallows .read; we use notify/write/writeWithoutResponse to avoid exposing plaintext attributes over GATT. +- BLE discovery, mesh routing, gossip sync, private delivery, and courier behavior +- Nostr private fallback, bridge courier drops, mesh bridging, geohash channels, and notices +- CoreLocation and reverse geocoding +- Local persistence, panic wipe, logging, and App Store privacy manifests -Mesh Routing and Multi-hop Limits -- Encrypted relays permitted with random per-hop delay (small jitter) to smooth floods. -- TTL cap: Encrypted payloads are capped at 2 hops, limiting metadata spread and path reconstruction risk while enabling close-range relays. +The user-facing contract is `PRIVACY_POLICY.md`. This document records implementation-level behavior and residual risks that should be re-audited when storage or transport semantics change. -Nostr Private Messaging Fallback -- Usage criteria: Only attempted for mutual favorites or where a Nostr key has been exchanged (stored in favorites). -- Payload confidentiality: Messages embed a BitChat Noise-encrypted packet inside a NIP-17 gift wrap; relays see only random-looking ciphertext. -- Timestamp handling: Gift wraps add small randomized offsets to reduce exact timing correlation. -- Read/delivery acks: Also encapsulated in gift wraps, preserving content secrecy and minimizing metadata. -- Relay policy variance: Some relays apply “web-of-trust” policies and may reject events; BitChat tolerates partial delivery and still prefers mesh when available. +## Current Posture -Read Receipts and Delivery Acks -- Routing policy: Prefer mesh if Noise session established; otherwise use Nostr when mapping exists. -- Throttling: Nostr READ acks are queued and rate-limited (~3/s) to prevent relay rate limits during backlogs. -- Coalescing (optional future): When entering a chat with many unread, only send READ for the latest message, marking older as read locally to reduce metadata. +- The project operates no account system, analytics pipeline, advertising SDK, or project-owned messaging backend. +- Mesh transport is peer-to-peer. Optional internet features use third-party Nostr relays and can expose public content, coarse geohashes, timing, relay, and network metadata. +- Private payloads are end-to-end encrypted, but public mesh, board, bridge, and geohash content is intentionally visible to its participants. +- Local storage is bounded where practical and included in panic wipe, but it is not wholly ephemeral. The app persists the stores listed below. +- The app and share extension each bundle a privacy manifest declaring their actual required-reason API use. +- A locked device discloses less than an unlocked one, but not nothing. Notification previews are hidden by default and the app-switcher snapshot is covered; see "Locked and Seized Devices". -Data Retention and State -- Messages: Ephemeral in-memory only; history is bounded per chat and trimmed. -- Read-receipt IDs: Stored in `UserDefaults` for UX continuity; periodically pruned to IDs present in memory. -- Favorites: Noise and optional Nostr keys with petnames; can be wiped via panic action. -- Panic: Triple-tap clears keys, sessions, cached state, and disconnects transports. +## BLE Discovery and Metadata -Logging and Telemetry -- Centralized `SecureLogger` filters potential secrets and uses OSLog privacy markers. -- Default level: `info`; release builds suppress debug. Developers can set `BITCHAT_LOG_LEVEL=debug|info|warning|error|fault`. -- Transport routing, ACK sends, subscribe/connect noise were downgraded from info→debug. -- OS/system errors (e.g., transient WebSocket disconnects) may still appear in system logs; BitChat avoids re-logging those unless actionable. +Signed announces can expose: -Residual Risks and Mitigations -- RF fingerprinting: BLE presence is observable at the RF layer; mitigated by minimal announce content and platform MAC randomization. -- Timing correlation: Announce/relay jitter reduces but does not eliminate timing analysis. Avoids synchronized bursts. -- Relay metadata: Nostr relays can see that an account posts gift wraps; content remains end-to-end encrypted. Favor mesh path when in range. +- Nickname, persistent Noise public key, and Ed25519 signing public key +- Capability flags +- A bounded set of short direct-neighbor identifiers +- A coarse rendezvous geohash when the bridge capability is enabled -Recommendations (Next) -- Add optional coalesced READ behavior for large backlogs. -- Expose a “low-visibility mode” to reduce scanning aggressiveness in sensitive contexts. -- Allow user-configurable Nostr relay set with a “private relays only” toggle. +The app does not advertise the device's assigned name. iOS manages BLE address randomization; bitchat does not attempt to create a stable MAC address. +That randomization does not deliver the unlinkability it might suggest, because the application layer publishes stable identifiers above it. The 8-byte peer ID in every packet header is the first 8 bytes of the Noise static key fingerprint, so it does not rotate; announces carry the static keys themselves; and the fixed service UUID makes any bitchat device detectable as such by a passive scanner. A receiver in radio range can therefore recognise a specific device across sessions and locations, and detect that the app is in use at all. RSSI, timing, traffic volume, and radio fingerprints remain observable as well. + +Ingress validates announce structure, sender binding, signatures, payload sizes, and freshness. Current-link Noise authentication is required before destructive courier handoff or strict directed delivery. Floods, queues, fragments, ingress work, and per-peer state are bounded. + +## Private Messaging and Courier Delivery + +- Direct mesh sessions use Noise XX with X25519, ChaCha20-Poly1305, and SHA-256. +- Undelivered outgoing private messages remain in a bounded, ChaChaPoly-sealed outbox for at most 24 hours. Its key is stored in the keychain. +- Physical couriers store opaque Noise-sealed envelopes, not plaintext. Deposits have trust-tier quotas, per-depositor caps, a global cap, and at most a 24-hour lifetime. +- Spray-and-wait copies are bounded and progress cannot be replenished by replaying a deposit. +- Delivery status advances only after real transport admission or explicit relay acceptance; late failure cannot downgrade a delivered/read message. +- Panic wipe deletes the outbox, courier mail, keys, dedup state, and active transport state. + +Residual risk: private-message metadata such as timing, radio adjacency, ciphertext size, rotating recipient tags, and relay connections remains observable. A compromised recipient device can disclose plaintext. + +## Public Gossip, Boards, and Media + +- Recent signed public mesh messages are archived in Application Support for up to 6 hours so gossip sync survives a relaunch and can cross mesh partitions. +- Signed public board posts and tombstones persist until author-selected expiry, at most seven days. Stores are bounded by global and per-author quotas. +- Group metadata (name, roster, creator, epoch) persists as protected JSON; group keys live in the keychain until leave/removal/wipe. +- Voice notes and images are stored in Application Support. Incoming media has a 100 MB oldest-first quota, and all managed media — incoming and outgoing — is additionally bounded by age: a launch-time sweep deletes anything older than seven days. In-flight live captures and files reserved by a delivery or deletion in progress are exempt regardless of age. Panic wipe invalidates detached preparation work, cancels active transfers, closes live capture files, and removes the managed media tree before returning. + +Public archives contain content already intended for public mesh/board distribution, but a seized unlocked device can reveal it. Group metadata and media can reveal relationships or content even when the in-memory chat timeline has gone away. + +## Nostr and Mesh Bridge + +- BitChat's proprietary private-envelope fallback protects plaintext with secp256k1 key agreement, HKDF-SHA256, and XChaCha20-Poly1305. It is not NIP-17, NIP-44, or NIP-59 compatible and does not provide forward secrecy against later compromise of the recipient's static Nostr private key. Relays still see the recipient public-key tag, event timing and size, and network metadata. +- Bridge courier drops use a throwaway publisher key, an opaque Noise-sealed envelope, and a day-rotating recipient tag. Only a party already holding the recipient's Noise static key can compute candidate tags. +- Relay publication is considered successful only after an explicit NIP-01 `OK true` from at least one target relay. Rejected, disconnected, timed-out, or merely socket-written events stay retryable. +- When mesh bridge is enabled, public mesh messages not marked “nearby only” are signed under a per-cell Nostr identity and published to a neighborhood rendezvous geohash. Presence and public bridge traffic therefore expose a coarse area to relays and participants. +- A bridge gateway can carry signed bridge/location events and opaque courier drops for nearby mesh-only peers. It cannot validly publish a neighbor's radio-only message because the author must first sign the bridge event. + +- Relays added by hand persist in local preferences (`nostr.customRelays`, at most 8, normalized on read) and are wiped on panic. An added relay names an operator someone chose to route through, so it is treated as sensitive local state rather than inert configuration. `.onion` addresses are accepted, which is the point: the four built-in relays are well-known clearnet hostnames and a filter blocking four names would otherwise end internet-delivered private messages until a new build shipped. +- Turning the Tor preference off routes relay sockets and the relay-directory fetch directly, disclosing the device IP to every relay operator including those carrying private messages. The settings UI states this while the preference is off. + +Residual risk: Nostr relay retention and logging are outside project control. Public events may be copied indefinitely. Timing, coarse location, and participation can be correlated even when content is encrypted or per-cell identities are used. + +## Location + +- When-in-use CoreLocation access computes geohash choices and bridge cells. Permission revocation stops live sampling and releases subscriptions. +- Exact coordinates are not persisted by bitchat or placed into mesh/Nostr payloads. +- Selected/bookmarked geohashes, teleport flags, and display names persist in local preferences; a fine geohash can identify a small area. +- Friendly place names use `CLGeocoder.reverseGeocodeLocation`. Apple may process the supplied location under its own privacy terms, so this operation is not accurately described as wholly on-device. +- Automatic presence is limited to lower-precision geohashes; precise posts occur through user-selected channels, notes, notices, or the bridge behavior presented in the UI. + +## Logging and Telemetry + +- `SecureLogger` uses OSLog privacy markers and filters likely secrets. Release builds suppress debug verbosity. +- No project analytics or telemetry endpoint exists. +- Apple system logs, Nostr relays, network providers, and nearby radios can still observe operational metadata outside the project's logging layer. + +## Privacy Manifests + +`bitchat/PrivacyInfo.xcprivacy` declares: + +- UserDefaults: `CA92.1` for app-only preferences and `1C8F.1` for the shared app group +- File timestamps/metadata: `C617.1` for app-container files and `3B52.1` for user-granted files +- System boot time: `35F9.1` for elapsed-time deadlines and timers + +`bitchatShareExtension/PrivacyInfo.xcprivacy` declares app-group UserDefaults reason `1C8F.1`. Both manifests declare no tracking domains and no data collection by the app developer. They must remain bundled in their respective executable bundles. + +## Locked and Seized Devices + +The realistic compromise for many of the people this app is built for is not interception but a phone taken and, often, unlocked under coercion. + +- Notification content is rendered by the system on the lock screen, so it is readable without unlocking. Message previews are therefore hidden by default: alerts state that a direct message, mention, or location-channel activity arrived, and withhold the message body, the sender's nickname, and the geohash until the app is opened. `userInfo` still carries the routing peer ID and deep link, neither of which the system displays. The preference is `notifications.hideMessagePreviews`; turning it off restores full previews. +- The window is covered on `willResignActive`, so the snapshot iOS stores for the app switcher shows a placeholder rather than an open conversation. The cover is opaque rather than blurred, and is added synchronously because the capture follows shortly after that notification. Panic wipe separately deletes snapshots already on disk. +- Clearing a mesh timeline erases the on-disk gossip archive behind it, so cleared public history is deleted rather than hidden. The echo watermark still suppresses pre-clear messages this device hears again from peers. +- Managed media is bounded by age as well as size, so a received photo does not outlive its conversation indefinitely. + +Not addressed, and deliberately out of scope here: + +- **No duress mechanism.** There is no decoy passphrase, no wipe-on-failed-authentication, and no biometric or passcode lock on the app itself. A coerced unlock discloses everything the device still holds. Adding one is a product decision as much as an engineering one: in some jurisdictions destroying data on demand is itself an offence, so a mode that *hides* may protect someone better than one that *destroys*, and the choice should be made deliberately rather than by default. +- **macOS gets no file-protection classes.** Every `FileProtectionType` application is inside `#if os(iOS)`; Data Protection on macOS additionally requires an entitlement. The Mac app also has no app-switcher equivalent. +- **Media is not sealed at the app layer.** It relies on the platform default protection class, which is readable once the device has been unlocked since boot. Sealing under a key with the same accessibility would not change that; only a key gated on user authentication would, and that conflicts with receiving media while locked. + +## Panic Wipe Coverage + +The panic action clears identity/session state, preferences, location state, groups, prekeys, outbox mail, courier mail, bridge dedup state, gossip archive, board data, managed media, hand-added relays, and active subscriptions/transports. Managed media deletion completes synchronously, after active media work has been invalidated. Keychain secrets use device-only accessibility, and an install marker detects and clears app keys that survive uninstall before a later reinstall can use them. New persistent stores must add an explicit wipe hook and a regression test. + +## Release Review Checklist + +- Reconcile every new Application Support, UserDefaults, keychain, cache, or relay write with this assessment and `PRIVACY_POLICY.md`. +- Re-scan required-reason APIs and validate both bundled `PrivacyInfo.xcprivacy` files before archive submission. +- Verify panic wipe reaches any newly added persistent store. +- Treat geohash precision, bridge-cell changes, new relay tags, and announce fields as privacy-surface changes. +- Re-run real-device Bluetooth, background/locked-device recovery, location revocation, and audio-route checks; simulators cannot validate the physical side of those behaviors. +- Check what a new notification discloses on a locked screen, and that the app-switcher snapshot is covered, whenever notification or scene-lifecycle code changes. diff --git a/localPackages/Arti/Frameworks/arti.xcframework/Info.plist b/localPackages/Arti/Frameworks/arti.xcframework/Info.plist index 5e9b24d6..42143638 100644 --- a/localPackages/Arti/Frameworks/arti.xcframework/Info.plist +++ b/localPackages/Arti/Frameworks/arti.xcframework/Info.plist @@ -4,22 +4,6 @@ AvailableLibraries -
