Apple's Privacy Rule Gaps Trigger Concerns: FT

Apple Inc AAPL has been forced to tighten its April privacy rules following warnings regarding user data collection despite opting out of tracking, the Financial Times reported.
Third parties continue to identify non-consenting users by employing different methods triggering confusion over the iPhone maker’s new policies.
A vendor reportedly managed to continue collecting data on over 95% of its iOS users through a secret method called “fingerprinting” despite Apple’s ban on the tactic.
Some ad tech groups believed that the probabilistic identification methods could bypass Apple’s new norms as the method depended on temporary, aggregated data instead of unique or permanent device IDs.
Marketing strategy consultant Eric Seufert expects Apple to elaborate on the matter shortly and possibly during its annual developers’ conference on Monday.
Seufert drew parallels with Alphabet Inc GOOG GOOGL Google’s multiple lawsuits for not turning off its location history in 2018.
Price action: AAPL shares traded lower by 0.39% at $125.05 on the last check Monday.
