End-to-end encrypted messenger
Private by construction. The server is a dumb relay — you keep the keys, the history, and the trust.

What you can count on
Messages are encrypted on your device before they leave it. The server only ever sees ciphertext it cannot read.
Sign up with a handle you choose — no phone, no email, no address-book upload. Opt-in private discovery is on the native-apps track; even then, your contacts never leave your device.
Keys and history live on your devices, and the server keeps an encrypted backup only your password can open. Forget it and there is no reset — by design.
Messages sync from your encrypted mailbox. The client is explicit about what has been delivered and what is still pending.
