Briar

Secure messaging, anywhere
Briar is a messaging app designed for activists, journalists, and anyone else who needs a safe, easy and robust way to communicate.

Unlike traditional messaging apps, Briar doesn't rely on a central server - messages are synchronized directly between the users' devices.

If the Internet's down, Briar can sync via Bluetooth or Wi-Fi, keeping the information flowing in a crisis. If the Internet's up, Briar can sync via the Tor network, protecting users and their relationships from surveillance.

You can link Briar with a device running Briar Mailbox (even on Android: org.briarproject.mailbox) to receive encrypted messages from your contacts while Briar is offline.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
