Signal
Say hello to a different messaging experience focused on privacy.

Signal is a free, open-source messaging app that offers end-to-end encrypted text, voice, and video communications. It is developed by an independent nonprofit and funded entirely by grants and donations, with no ads or trackers. The app is available to anyone and is designed to make privacy the default, not an optional feature.
Signal uses the open-source Signal Protocol to apply end-to-end encryption to all messages, calls, and media by default, over a standard internet data connection.
