Signal is a Secure Way to Message

Signal is a state-of-the-art end-to-end encryption (powered by the open-source Signal Protocol) keeps your conversations secure. We 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. There are no ads, no affiliate marketers, and no creepy tracking in Signal. Focus on sharing the moments that matter with the people who matter to you. Signal is an independent nonprofit. Development is supported by grants and donations from people like you.
