Signal is free and open-source. It cannot be denied that basically everything, including minor details like usernames, is end-to-end encrypted and kept secure. The Signal protocol has been proven to be secure by many independent experts and thus it is mathematically impossible for Signal to gain access to your sensitive information (except for your phone number, obviously).
