Lyra: Secure Messenger

Lyra is the secure messenger for people who can't compromise on privacy.

Every message, call, and file is protected end-to-end with post-quantum cryptography - encryption designed to stay secure even against a future quantum computer. It's the same class of algorithm (CNSA 2.0: ML-KEM-1024) that national-security systems require.

QUANTUM-SAFE BY DESIGN
- End-to-end encryption with hybrid X25519 + post-quantum ML-KEM-1024
- AES-256-GCM message encryption - the CNSA 2.0 suite
- Your keys stay on your device; the server only ever sees ciphertext

EVERYTHING YOU NEED
- Private 1:1 and group messaging with reactions, replies, edits
- Disappearing messages
- Encrypted file sharing and voice messages
- Group voice and video calls, with screen sharing
- Favorites, folders, and archive to stay organized

BUILT FOR TRUST
- No phone number required - sign up with email, never tied to your identity
- Two-factor authentication with an authenticator app (TOTP)
- Verify conversations by comparing post-quantum fingerprints
- A new device never receives your old messages unless you restore an encrypted backup
- Self-hosted: runs on infrastructure your organization controls
- No user directory, no federation, minimized metadata

Lyra. Collaborate without compromise. Quantum-safe.
