Signal Messenger

Open technology for a fast, simple, and secure messaging experience

Say "hello" to a different messaging experience. An unexpected focus on privacy, combined with all of the features you expect.

State-of-the-art end-to-end encryption (powered by the open source Signal Protocol) keeps your conversations secure. They can’t read your messages or listen to your calls, and no one else can either. Privacy isn’t an optional mode — it’s just the way that Signal works. Every message, every call, every time.
