About
SimpleX Chat is an end-to-end encrypted messaging app that requires no user IDs of any kind, ensuring complete anonymity. All messages are routed through servers as random noise, and contacts and groups are stored only on the user's device. Anyone can run their own SimpleX servers, making the network decentralized and user-owned.
Problem
Mainstream messengers require user IDs and store metadata on centralized servers, exposing who users communicate with.
For
Privacy-conscious individuals and communities seeking anonymous, decentralized communication
How it works
Messages are routed through servers as indistinguishable random noise with no user identifiers; connections are made via link or QR code and all contact data stays on the user's device.
