Briar
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 information flowing in a crisis. If the Internet's up, Briar can sync via the Tor network, protecting users and their relationships from surveillance.

Reproducible builds
We provide docker images to ease the task of verifying that the published APK binaries include nothing but our publicly available source code.
You can either use those images or use them as a blueprint to build your own environment for reproduction.
