Surprise, shock: it seems some iPhone apps nonetheless observe customers even after they use Apple’s new App Tracking Transparency characteristic to keep away from being tracked.

For those that will not be acquainted with it, Apple added App Tracking Transparency in an replace to iOS 14 earlier this yr. The characteristic lets customers block apps from accessing their gadget’s Identifier for Advertisers (IDFA), a form of promoting identification quantity tied to a tool. The change ought to forestall apps from sharing knowledge gathered about you out of your iPhone or iPad with third-party corporations (for instance, Instagram may nonetheless share knowledge with Facebook since they’re the identical firm).

Unfortunately, what ought to occur and what does occur are sometimes fully various things. And in accordance with an investigation from The Washington Post together with privacy-focused app developer Lockdown (through Input), some apps and video games ignore customers’ settings.

Of the ten apps studied, Lockdown discovered that none stopped monitoring when customers requested to not be tracked. The investigation discovered a minimum of three in style iPhone video games, together with Subway Surfers, despatched person knowledge to third-party promoting corporations, regardless if customers had enabled App Tracking Transparency. Worse, the investigation discovered that Apple had finished nothing to cease it, regardless of being alerted to the difficulty.

Blocking IDFA entry doesn’t matter as a result of apps can fingerprint customers with different knowledge

Here’s the factor — blocking an app’s entry to your IDFA really works, in essentially the most barebones, primary means. The apps studied within the investigation didn’t have entry to customers’ IDFA and didn’t use it for monitoring. Instead, they successfully created their very own IDFA for units by gathering varied different metrics.

Going again to the Subway Surfers instance, the investigation discovered it despatched 29 knowledge factors about customers’ units to an advert firm referred to as ‘Chartboost.’ Some of the info factors included customers’ IP tackle, remaining free storage, present quantity degree, accessibility settings, gadget identify, time zone, nation, service and extra.

Gathering a bunch of gadget knowledge like that is really a standard monitoring tactic referred to as fingerprinting. By gathering a considerable amount of seemingly innocuous knowledge a few customers’ gadget, corporations can successfully observe that gadget (and, by extension, the person) throughout varied apps and platforms.

Few of the builders behind the apps responded to requests for remark from The Washington Post. However, Subway Surfers developer Sybo did, and claimed it gathered the info “for the game to function properly.” While perhaps a number of the knowledge factors may assist the sport work — for instance, getting accessibility settings may assist the sport accommodate customers who depend on these choices — many of the knowledge should not have any impression on the operate of the sport.

Apple must do extra if it desires to be a privacy-first firm

More than something, the investigation demonstrates that Apple’s App Tracking Transparency characteristic is, in the end, not that useful. Worse, it might even be detrimental by lending customers a false sense of safety. Apple’s successfully telling customers that they don’t have to fret about being tracked if they allow the characteristic. App Tracking Transparency additionally bolsters the corporate’s privacy-first picture — I’ve seen loads of social media posts about how App Tracking Transparency satisfied individuals to change from Android to iPhone to enhance their privateness.

If Apple had been actually critical about privateness, it could add fingerprinting safety to iOS to scale back or hopefully cease monitoring practices like this. In its present kind, App Tracking Transparency is, at finest, shallow advertising. At worse, it’s detrimental to person privateness by tricking individuals into pondering they’re protected after they aren’t.
