About Signal
Signal is a messaging service with privacy as its default setting. It is operated by an independent nonprofit that is not tied to major tech companies. Messages and calls are protected with end-to-end encryption based on the Signal Protocol, so the service cannot read messages or listen to calls.
With Signal you can send text, voice messages, photos, videos, GIFs, and files using your phone's data connection instead of SMS and MMS. You can also make voice and video calls, take part in group chats, and use encrypted stickers, including packs you create and share yourself.
