Features

Everything you need to stay private.

Designed to be simple. Built to be uncompromising.

Private messaging

Every message is end-to-end encrypted on your device. Even we can't read them.

Crystal-clear calls

High-quality voice calls protected by perfect forward secrecy. No call logs.

SMS verification

One-time codes and security alerts keep your account safe. No marketing, no bulk messaging — ever.

Your keys, your data

Private keys never leave your device. You own every conversation.

Zero metadata

We don't store who you talk to, when, or for how long. Nothing to leak.

Biometric lock

Face ID and fingerprint guard your vault. Privacy you can feel.

Security

Four layers of silence.

Engineered like a bank vault — every layer independent, every key ephemeral, every byte verifiable. Audited cryptography. Open protocols. No shortcuts.
