The app automatically links with your existing contacts so you can see who else you know is using the app. Once a message is sent, only the recipient knows who it is from. These features allow for secure and private messaging and mean that your conversations are not saved on your device or the app. You can also set ‘view once’ content which means once your content has been sent and seen by the person you’ve sent it to, the content disappears. This can be anywhere between 5 seconds to one week - after it reaches the time limit, the message disappears.

Your messages can be set to ‘disappearing messages’ which means you can set a time limit on how long your messages will last once they have been sent to a contact. You can send messages, make audio and video calls, send voice notes, images and videos to your contacts which are secure, untracked and free.

Signal is an encrypted private messaging app owned by the Signal Foundation.
