The world's most secure messaging

Ultimate security: end-to-end encryption with continuous post-quantum key exchange protects messages and metadata.

Unique privacy: no user profile IDs—not even random numbers. Servers cannot build a social graph from your account.

No spam: nobody can message you unless you share a one-time link or long-term address.

Data ownership: profiles, contacts, and messages live on your device. Move your profile securely to another device.

Decentralization: you pick which servers to use; multiple servers participate in each conversation.
