Briar

Aplicación Descentralizada

A messaging app for activists, journalists and anyone who needs a safe and robust way to communicate. Unlike conventional messengers it has no central server: messages are synchronised directly between users' devices. If the internet is down, Briar can sync over Bluetooth, Wi-Fi or memory cards; if it is up, it syncs over the Tor network to hide who is talking to whom. Briar Mailbox lets users who are online at different times exchange messages. Alongside private messaging it offers public forums and blogs, each user's contact list is encrypted and stored on their own device, and all communication between devices is end-to-end encrypted. Briar is for Android, with a desktop version in development .
