P2P Zero-Trust Chat

About

P2P Zero-Trust Chat is a Chrome extension for private messaging and voice calls between two people. After you connect, messages and audio travel directly between devices over WebRTC — encrypted end-to-end. There is no central chat server storing your conversation history.
HOW TO START
1. Create a room and give it a name (stored only on your device).
2. Create a magic code or share your room hash with your peer.
3. Your peer enters the code on the Connect tab.
4. Compare the security code (6 emoji) out-of-band — voice, in person, or another app.
5. Tap “Codes match — I trust”. P2P opens — you can chat and call.
KEY FEATURES
• End-to-end encrypted text (NaCl / Curve25519 + Ed25519 signatures)
• Direct P2P messaging via WebRTC — no plaintext chat on our servers
• Magic invite codes (~30 min) for easy pairing
• Security code (SAS) verification against man-in-the-middle on first contact
• Voice calls over P2P WebRTC audio
• Popup or side panel mode, unread badge, desktop notifications
• English and Russian interface
HOW IT WORKS
A lightweight signaling service (signal.vlk.by) helps browsers find each other and exchange WebRTC setup data — like a phone book, not a messenger. It does NOT store your chat text. Encrypted messages go directly peer-to-peer once the channel is open.
WHAT WE STORE
• On your device: keys, rooms, decrypted message history (local only), settings
• On signaling server: temporary public keys, WebRTC offers/answers, magic sessions (~30 min TTL) — no message content, no accounts, no passwords
PRIVACY
• No analytics, no ads
• Private keys never leave your device
• Optional link shortening (vlk.by) only when you choose it
• Microphone access only for voice calls
PERMISSIONS
• storage — keys, rooms, messages, settings
• offscreen — WebRTC in Manifest V3
• sidePanel — side panel mode
• notifications — alerts when chat is closed
• signal.vlk.by — signaling only
Best for two-party secure chats where you verify your peer via the emoji security code. Not a cloud-synced multi-device messenger.
