Signal is a messaging app with privacy at its core. It is free and easy to use, with strong end-to-end encryption that keeps your chats and calls completely private. Signal can't read your messages or listen to your calls, and no one else can either. 

• Signal on MacOS links with Signal on your phone. 

• Send end-to-end encrypted texts, voice messages, photos, videos, GIFs, and files for free. 

• Stay connected with group chats up to 1,000 people. Control who can post and manage group members with admin permission settings.

• Call your friends with crystal-clear end-to-end encrypted voice and video calls. Group calls support up to 75 people.

• Signal is built for your privacy. We know nothing about you or who you’re talking to. Our open source Signal Protocol means that we can’t read your messages or listen to your calls. Neither can anyone else. No back doors, no data collection, no compromises. 

• Share photo, text, and video Stories that disappear after 24 hours. Privacy settings keep you in charge of exactly who can see each Story.

• Signal is independent and not for profit; a different kind of tech from a different kind of organization. As a 501c3 nonprofit we are supported by your donations, not by advertisers or investors.
