What is Signal

Signal is a free app for talking and messaging that is very private. It helps you keep your conversations safe from others who might want to read them. Signal uses special ways to make sure only you and the person you are talking to can see what you send. This means your messages, calls, and videos are kept secret.

How it Works

Signal uses something called end to end encryption. This is like a secret code that scrambles your messages. Only the person you send the message to has the key to unscramble it. This happens automatically so you do not need to do anything special. Your messages are sent directly from your device to their device. Signal does not store your messages on their servers after they are delivered.
