Unlisting does not mean that the info is removed.

If they have full access on anyone having installed the app, it means they also have mined the conversations with your contacts.

So they might not advertise what they know anymore, but the privacy concern remains anyway.

Yes but atleast you're not visible to others edit: so in order to use this, you have to install the app - "deactivate it" and only then will it accept the unlisting. Fucking bs

BS but I imagine this is how they verify you own the number and prevent a rival app from executing a denial of services attack on them by unlisting everyone’s number.

This could also have been done using a simple OTP and on the number.
