Nowadays, a majority of apps require you to sign up with your email or even worse your phone number. If you have a phone number attached to your name, meaning you went to a cell service/phone provider, and you gave them your ID, then no matter what app you use, no matter how private it says it is, it is not private. There is NO exception to this. Your identity is instantly tied to that account.
Signal is not private. I recommend Simplex or another peer to peer onion messaging app. They don’t require email or phone number. So as long as you protect your IP you are anonymous
Ah… I guess I didn’t understand how services like encrypted webmail worked. I’ve only ever used local pgp with thunderbird or whatever. I was assuming (incorrectly) that those services operated in the same manner. Thanks for explaining it to me.
You are correct, encrypted mail providers should encrypt on-device, before sending the mail, but there isn’t a solution to the unencrypted mail you could potentially recieve being intercepted.
