On: Epic Games Store and Fortnite Arrive on EU iPhones

Facebook also uses the iOS Keychain to track you across app installs and deletions, AND even when restoring iCloud backups on a new phone! There's no way to see or delete that data without using Facebook apps, and no way to be sure that the data they show is all the data they've stored on your phone.

If I have a meta app, where can I see this stuff?

You can't because Facebook won't show it to you and Apple doesn't allow their users access to the phone internals :)

Match made in heaven?

It's most visible in the "Saved Logins" where it shows you all the accounts you've ever used.

That sounds unlawful under GDPR?
