- I added a first name to my conversation contacts, but it keeps showing the phone number. In the app and in notifications.

- There is a fixed pop under at the bottom of the screen asking me to confirm my profile name, with “Get Started” or “remind me later” (which is apparently every time i come back to the app), and no “never“ option. I had already put a first name but that’s not good enough. Had to do it again to confirm i don’t want to share a last name with him / them.

- why does he care about the distinction between a “first name” (mandatory) and “Last Name” (optional)

-> Only the user should care about the name.

=> Why should the app / he / them get access to my contacts list to update a contact name? I’m perfectly willing to have duplicate contacts siloed in a “secure messaging app”.

Also, could someone explain why the app need phone numbers ? They only send some initial token over SMS, which can be spoofed.

The phone number deregister flow is such a dark pattern it's incredible. Not something a chat app should ever do to be reputable.

How so?

If you uninstall the app it has a seven day forced delay for releasing your phone number, it isn't disclosed anywhere and the form just silently errors out when seven days haven't passed.
