Private messaging. No servers. No accounts.·zerion.chat
Zerion is an end-to-end encrypted messenger that routes all traffic over Tor, with no central servers and no phone number required. Messages, voice/video calls, and files travel peer-to-peer between devices via Tor circuits meeting at a rendezvous relay. It uses hybrid post-quantum cryptography (ML-KEM-768, ML-DSA-65) alongside Triple Ratchet encryption for messaging, groups, and channels. The app is free, open source under GPL v3, and available for Android.
