> The practical consequence of this is that your phone number + name is public information. From the paper: > With its focus on privacy, Signal excels in exposing almost no information about registered users, apart from their phone number. In contrast, WhatsApp exposes profile pictures and the About text for registered numbers, and requires users to opt-out of sharing this data by changing the default settings. So if you only use Signal you don't leak the connection between your profile (which could contain your name) and your phone number, at least not until you accept a message from an attacker.
