Your iOS app may still be covertly tracking you, despite what Apple says
Last year, Apple enacted App Tracking Transparency, a mandatory policy that forbids app makers from tracking user activity across other apps without first receiving those users’ explicit permission. Privacy advocates praised the initiative, and Facebook warned it would spell certain doom for companies that rely on targeted advertising.
However, research suggests that ATT, as it’s usually abbreviated, doesn’t always curb the surreptitious collection of personal data or the fingerprinting of users. Researchers say that while ATT in many ways works as intended, loopholes in the framework also provided the opportunity for companies, particularly large ones like Google and Facebook, to work around the protections and stockpile even more data. The paper also warned that despite Apple’s promise for more transparency, ATT might give many users a false sense of security.
