Data so stripped no one's identifiable—by you or anyone with reasonable means. Not just delete name. Phone + GPS? Still personal.

Why was Taxa 4×35 fined 1.2 million kroner?

Hoarded 9M rides' data too long. Deleting names didn't anonymize—phone numbers allowed re-ID. Violated minimization, storage limits.
