Security You Can Understand
Your conversations are protected on your devices. Public documentation explains the security properties you can independently inspect without exposing private infrastructure or user data.
End-to-end encryptionLocal key protectionPublished test vectorsResponsible disclosure
Private by design
Private communication does not require a phone number, public user directory or advertising profile. Encryption is the same across every subscription.
Transparent distribution
Official downloads include published integrity information and a public record suitable for verifying the distributed application.
Honest security claims
We describe only protections supported by the published application and do not represent internal testing as an independent security audit.
Your privacy is not a premium feature.
We do not sell user data, insert advertising or weaken encryption for people using the free plan.
Private because you pay us. Not because somebody pays for you.
