## What is PeerDrop?

PeerDrop lets you share files, chat, and make voice calls directly between devices on your local network — no internet, no cloud, no accounts required.

KEY FEATURES

- Direct File Transfer: Send photos, videos, documents, and any file type directly to nearby devices. Files are chunked and verified with SHA-256 hashes for integrity.

- Encrypted Chat: Send text messages, photos, videos, and voice messages with end-to-end encryption. All chat history is stored locally and encrypted with AES-256-GCM.

- Voice Calls: Make crystal-clear voice calls using WebRTC, fully integrated with iOS CallKit for a native calling experience.

- Device Discovery: Automatically find nearby devices on your Wi-Fi network using Bonjour. Or connect manually by IP address.

- Multi-Connection: Connect to up to 5 devices simultaneously. Each connection has independent chat, file transfer, and voice call capabilities.

- Device Library: Save frequently connected devices for quick reconnection. Organize them into groups.

- Privacy First: No servers, no accounts, no tracking. Everything stays between your devices. All connections use TLS encryption with trust-on-first-use verification.

HOW IT WORKS

1. Open PeerDrop on two devices connected to the same Wi-Fi network
2. Devices discover each other automatically
3. Tap to connect — the receiving device approves the connection
4. Start sharing files, chatting, or making voice calls

SECURITY

- TLS-encrypted connections with ephemeral P-256 key pairs
- AES-256-GCM encryption for stored chat data
- Certificate fingerprint verification (trust-on-first-use)
- SHA-256 file integrity verification
- No data ever leaves your local network

## Version history (last 5 releases)

### 5.6.0 — 2026-07-11

PeerDrop 5.6.0 — your pet, now in your language, plus security & reliability hardening.

Localized pet labels: your companion's species, food, mood, and life stage now appear in your device language (English, 日本語, 한국어, 简体中文, 繁體中文). Previously these read in Chinese for everyone.

Under the hood: hardened how encrypted messages are handled — a malformed packet can no longer disrupt a session — and shipped builds no longer embed a relay-server key. Nothing to configure; it just works.

Compatibility: 5.6.0 connects to earlier v5 peers exactly as before. The on-wire protocol is unchanged.

### 5.5.2 — 2026-06-22

PeerDrop 5.3 — Push notifications are working again, and connecting to the relay server is now hardened.

Push notifications: v5.0–v5.2 shipped with the iOS push entitlement missing. The app registered for remote notifications and iOS silently rejected it, so background invites from your peers never reached you. Fixed in this release. If you accepted notification permission on a prior version, the next launch will pick up the registration automatically.

Better relay-server authentication: previously every install of PeerDrop carried the same shared API key inside the app, which would let anyone who unpacked the .ipa hit the relay server on your behalf. v5.3 uses Apple's App Attest framework instead — your device cryptographically proves it's a legitimate iOS install before the server hands out tokens. The proof key lives in the Secure Enclave and never leaves your device. There's nothing to configure; it just works in the background.

Polish:
- The "first time meeting this peer" pairing sheet from v5.2 now handles concurrent connections cleanly instead of queueing one silently behind the other.
- The sort menu in the "Nearby" tab no longer flickers a stray empty icon on the non-selected options.

Compatibility: v5.3 still talks to v5.0–v5.2 peers exactly as before. The on-wire protocol version is unchanged.
