Mercury

Unsync

About this app

Mercury is a P2P encrypted messenger that connects you directly to the people you trust — no central servers storing your messages, no middlemen reading your data.

Every message and call is end-to-end encrypted using the Signal Protocol. Your conversations exist only between you and the person you're talking to.

Features:
- Peer-to-peer messaging — no server stores your chats
- Encrypted voice calls via WebRTC
- End-to-end encryption using Signal Protocol
- QR code contact discovery
- Works across networks and carriers
- Minimal permissions, no data collection

Mercury is built for people who believe private communication should actually be private.
