       | opportunity on existing discussions about Facebook to bring it
       | up:
       | 
       | Facebook (and TikTok) store tracking data on iOS that the user
       | CANNOT SEE and CANNOT DELETE:
       | 
       | * It shows my previous account even after I delete the app.
       | 
       | * Clearing Safari's cache does not work.
       | 
       | * Disabling iCloud Drive and iCloud Keychain does not work.
       | 
       | * Even completely signing out of iCloud does not work!
       | 
       | * On a Mac in the Terminal, you can go to ~/Library/Mobile
       | Documents and "ls -al" to see hidden folders like
       | "iCloud~com~Facebook~Messenger" that you cannot otherwise view or
       | delete.
       | 
       | * Someone mentioned that even RESTORING an iCloud BACKUP will
       | resurrect these "eternal cookies"!!

       | 
       | WHERE do they store this data?
       | 
       | WHY can't the user see this data?
       | 
       | WHY can't the user delete this data without going through the
       | app?
       | 
       | WHAT ELSE do apps store on our devices that we aren't even aware
       | of? (This is just what we can _see:_ The list of saved accounts
       | for  "quick login")
       | 
       | HOW MANY other apps are secretly doing this?

         | 
         | Good alliteration.
         | 
         | Apple doesn't _enforce_ what the app does with app data. Apple
         | makes sure that if the app uses a platform API that is
         | sensitive, it gets your opt-in (or prohibits the use of the API
         | altogether). Apple makes sure that the app publishes a privacy
         | nutrition label. But what the app does inside with whatever
         | data you choose to give it, that's up to the app.
         | 
         | If you voluntarily _choose_ to give data to the app, what the
         | app does with it is your problem. Apple just tries to make sure
         | the app can't _take_ data that you haven't chosen to give it.

         | Hey I can shed light on this. It's the iCloud keychain.
         | Disabling the keychain doesn't delete existing entries. There
         | is no way to modify the keychain on iOS (you can on Mac). Lots
         | of apps store sign on data in the keychain for obvious reasons.
         | 
         | It would be really great to have a keychain section in iOS's
         | settings, like Keychain Access on Mac. The dev can build in-app
         | functionality to delete keys from the keychain, but there's not
         | a huge incentive to.
         | 
         | Keychain storage doesn't let FB track you, just store sign on
         | info, keys, and the like. It's not able to execute arbitrary
         | code, it's an encrypted place to store login info that Apple
