# 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. ## Download Briar [](https://briarproject.org/fdroid) [](https://play.google.com/store/apps/details?id=org.briarproject.briar.android) You can also [download the APK file](https://briarproject.org/apk) directly from our site. ## Useful links [Project website](https://briarproject.org/) [Source code](https://code.briarproject.org/briar/briar/tree/master) [User manual](https://briarproject.org/manual/) [Wiki](https://code.briarproject.org/briar/briar/-/wikis/home) [Privacy policy](https://briarproject.org/privacy) ## Reproducible builds We provide [docker images](https://code.briarproject.org/briar/briar-reproducer#briar-reproducer) to ease the task of verifying that the published APK binaries include nothing but our publicly available source code.
