Signal

Signal is a messaging app with privacy at its core. It's simple to use and free, offering a completely private chat and call experience through strong end-to-end encryption. Neither Signal nor anyone else can read your messages or eavesdrop on your calls. • Signal on Windows connects with Signal on your phone. • You can send end-to-end encrypted text, voice messages, pictures, videos, GIFs, and files for free. • Group chats can accommodate up to 1000 people, making it easy to connect with others. You can restrict who can post and manage group members in admin permission settings. • Clear end-to-end encrypted voice and video calls let you chat smoothly with your friends. Group calls support up to 75 people simultaneously. • Signal is built to protect your privacy. We do not collect information about you or your chat partners. Our open-source Signal Protocol ensures that we cannot read your messages or eavesdrop on your calls. No one is exempt. There are no backdoors, no data collection, and no compromises. • You can share photos, text, and video updates that automatically disappear after 24 hours. The visibility of each update can be adjusted in your privacy settings. • Signal is an independent, non-profit platform; different organizations create different technologies. We are a non-profit organization, supported entirely by user donations, with no advertisers or investors.
