Could you decrypt my messages, for example if you were required to by law enforcement?
No, that is impossible, as we don't have the secret keys of our users (your secret key never leaves your device). Our servers do need to know who is sending a message to whom, so that they can route it to the correct recipient, but they do not log this information, and cannot decrypt the message's content.
