Private messaging, built on real cryptography

A secure messenger for people who care about who can read their conversations. Every message, call, and file is protected with end-to-end encryption, so only you and the people you're talking to can access the contents. Not your network, not your carrier, not us.

Encrypted by default
The app implements the Signal Protocol, the same open cryptographic standard trusted by security researchers worldwide. Encryption keys never leave your device, and forward secrecy means past conversations stay protected even if a key is ever compromised.

Voice and video calling
One-to-one and group calls with clear audio and video. Group calls are encrypted end to end, with keys rotating automatically as people join and leave. Incoming calls ring natively on your device, so you never miss one.

Everything you'd expect from a messenger
• One-to-one and group chats
• Photo, video, and file sharing with full-screen viewing and zoom
• Delivery and read receipts
• Mute conversations you don't need right now
• Link previews
• Fast, reliable notifications

Your data stays yours
Messages are stored in an encrypted database on your device, protected by SQLCipher. The app checks for compromised devices and blocks tampered network connections through certificate pinning. There are no ads, no message scanning, and no selling of your data.

Built to feel good on any screen
A clean, responsive interface that adapts to phones and tablets, with a split-view layout on larger displays.

Install now and start a conversation that stays between you and the person you're talking to.
