fun fact: its worse than that! its not only about your phone number. signal and almost every chat app exposes your chat partners in the system contacts database. It's handy for the contacts app to be showing the list of chat apps usable for someone you know. at the minimum your name and profile picture that you set for yourself will be there and accessible to any apps with contacts permission, and in signal (even the molly fork) if that partner has made their phone number visible, that will be saved here too. and you can't really turn it off for others.
You are misinformed. Signal has your phone number and that's it. This has been demonstrated time and time again with legal documents.
check your contacts app before stating such things. I'm not stating that signal sends your data to facebook and such, but that signal is registering info into the OS for convenience, that will also he visible to other apps with the privilege granted, including those of facebook
Check my contacts app for what, exactly?
sorry, I think I was wrong. signal/molly only attaches that information to a contact when it already has the phone number that they use for signal.
so unless you keep your phone number visible on signal, or you share your phone number in another way, this shouldn't be a problem.
