Signal

About

Signal is a messenger with an unexpected focus on privacy, combined with the features you expect. Its state-of-the-art end-to-end encryption, powered by the open source Signal Protocol, keeps conversations secure. Signal says it can't read your messages or listen to your calls, and neither can anyone else. Privacy is simply how Signal works, for every message and every call.

You can share text, voice messages, photos, videos, GIFs, and files for free, using your phone's data connection to avoid SMS and MMS fees. Voice and video calls are crystal clear, with no long-distance charges. You can add encrypted stickers to your conversations, or create and share your own sticker packs. Group chats make it easy to stay connected with family, friends, and coworkers.

Signal has no ads, no affiliate marketers, and no tracking. It is an independent nonprofit that isn't tied to any major tech company and can never be acquired by one. Development is supported by grants and donations.
