Does anyone know WHERE the HELL Facebook stores tracking data on iOS?

It shows my previous account even after I delete the app, clear the cache and Keychain, disable iCloud Drive, AND sign out of iCloud??

Why can't I see where this data is stored? Same for TikTok.

WHY does Apple, parading around as a pompous paragon of privacy, even allow this shit?

Developers can store items in keychain on your device/icloud account that are only visible to the apps made by that developer (and not you). It is a feature that it works this way, and this whole concept is fucking insane to me.

So how can the user delete it without going through the app or wiping the entire phone?

What else is being stored that we aren’t even aware of?

On iPhones, three ways to get rid of the keychain data of an app 1. wipe the phone AND you must not restore backups 2. jailbreak the phone 3. the app can wipes its own keychain (but apps don’t expose this feature generally)
