Common

Common is a privacy-first social platform combining a chronological feed, end-to-end encrypted messaging, and calls in one app. Every message is protected by the Signal Protocol with post-quantum (Kyber/PQXDH) key exchange, and the feed carries no engagement-ranking algorithm and no ads by design. The platform supports real multi-device use and group messaging, disappearing messages, safety-number verification, and encrypted photo attachments. Users can export or permanently delete their data at any time, and a biometric app lock protects access on-device. End-to-end encrypted Messages, calls, and media are sealed on your device. Not even we can read them. No algorithm, no ads Your feed is chronological. Nothing is ranked to keep you scrolling, and nothing is sold to advertisers. You own your data Export everything as a signed archive, or delete it permanently, any time - no support ticket required. Decentralized by design Your data is relayed across independent nodes, not held in one company's database.
