Private messaging over a real mix network · hybrid post-quantum encryption
Your message keys are generated on this device and never leave it. Your password never leaves it either: it stays here, and the server only ever receives a value derived from it that it can check but not reverse. Your contact list is encrypted under a separate key derived from the same password, which the server never sees in any form.
Add a contact by their handle to start an end-to-end encrypted conversation.
Messages are end-to-end encrypted and delivered even when the other person is offline: they wait in an encrypted mailbox until that device reconnects. Your keys are generated on this device and never leave it. How it works
