# Session (open-source messaging app)

> Session is a free, open-source messaging app for Android. Encrypted private messenger. It has 916 GitHub stars and is released under the GPL-3.0-only license, and you can install it from F-Droid.

This is an unofficial rebrand of Session without Firebase push service so the "fast mode" can't be enabled. If you want to use the "fast mode" please use the official Session client from their own repo. Session is a new breed of encrypted private messenger, built on a unique network of user-operated servers spread all over the world. With no central servers, Session can't leak or sell your data. You don't need a phone number or email to sign up — your Session ID can stay completely anonymous. And Session's private routing protocols keep your messages secret and secure. No one ever knows who you're talking to, what you're saying, or even your IP address.
