About SimpleX Chat
SimpleX Chat is a messaging platform that assigns no user identifiers of any kind, not even random numbers. This hides who you talk to from the platform's servers and from any observers.
Messages use double ratchet end-to-end encryption with an additional encryption layer, and user data is stored on client devices. You start a conversation by sharing a one-time link or QR code, and you can use your own servers. The project provides mobile apps and a desktop client.
Highlights
- No identifiers assigned to users
- Protects messages and metadata
- Double ratchet end-to-end encryption plus an extra encryption layer
- Data kept on your devices, with relay servers holding messages only until delivery
- Connect through one-time invitation links or QR codes
- Option to use your own servers
