YEO uses double ratchet encryption.
This is recognized as one of the most secure encryption methods available and has yet to be broken.
We will continue to enhance the encryption and can introduce new encryption techniques and styles without interrupting your messaging.
Simply put, each time we send a message the encryption key is sent to your device ahead of the content, which resides on the server.
If we change the encryption key, we send a revised key to provide the user with a seamless experience.
