    Factory reset doesn’t delete persistent app data enabled by app developer [paraphrased]

    What about Erase All Content and Settings? You seriously can’t fully erase a second-hand phone you bought?! That’s insane

      Apple urges developers to not use DeviceCheck for anything beyond basic device verification, and if you’re a developer that’s also misusing it, then you should definitely cease that—there are probably more reliable ways to check whether it’s the same user trying to access an account from a device or not.

      I don’t think I care about not being able to erase the device ID. It seems useful to have this, actually, for back-tracing if need be.

      Snapchat probs shouldn’t use the DeviceCheck services improperly. But hey, that’s just like my opinion, man.

      More, not very interesting, info on DeviceCheck services here: https://developer.apple.com/documentation/devicecheck

      I can’t see what was posted above anymore, but the DeviceCheck API lets app developers store 2 binary digits (that means 4 different states: 00, 01, 10 or 11) per device on Apple’s servers. So, no, these don’t get erased during a Factory Reset as they’re stored on Apple’s servers. But your phone will.
