The New iOS Update Lets You Stop Ads From Tracking You—So Do It

Facebook and other advertisers fought the move, but App Tracking Transparency is finally here.

If you’re sick of opaque ad tracking and don’t feel like you have a handle on it, a new iOS feature promises to give you back some control. With the release of Apple’s iOS 14.5 on Monday, all of your apps will have to ask in a pop-up: Do you want to allow this app to track your activity across other companies‘ apps and websites? For once, your answer can be no.

A lot of the biggest data privacy crises of the past few years have come not from breaches but from all the opaque policies around how companies share user data and track those users across services for targeted advertising. Marketers assign your device an ID and then monitor your web and in-app behavior across different platforms to generate composite profiles of demographic information, purchasing habits, and life events. Apple has already taken a strong stand to disrupt ad tracking in its Safari browser; this iOS update brings the showdown to mobile. But while the step may seem like a no-brainer to iOS users, it’s been deeply controversial with companies built on ad revenue, including and especially Facebook.“This is a significant and impactful move,” says Jason Kint, CEO of the digital publishing trade organization Digital Content Next. (WIRED parent company Condé Nast is a member.) “The digital advertising business has been mostly built off of micro-targeting audiences. Facebook, as an example, has code embedded in millions of apps to collect data to target audiences wherever it wants as promptly as possible—and this cuts that off.”iOS already gave its users the option to turn off ad ID sharing completely, essentially zeroing out the unique identifier on your phone, known as IDFA, that iOS gives developers for in-app and cross-service tracking. iOS 14.5’s new requirements, though, compel each app to put the question to users individually through Apple’s AppTrackingTransparency framework, so you have more granular control. This allows you to grant the privilege to certain apps if, for example, you would rather see tailored ads on a particular service. But it also will simply expose how many apps participate in cross-service ad tracking, including some you may not have suspected.“We believe tracking should always be transparent and under your control,” Katie Skinner, an Apple user privacy software manager, said at Apple’s Worldwide Developers Conference last June. „So moving forward, App Store policy will require apps to ask before tracking you across apps and websites owned by other companies.“

Though the tracking changes in iOS 14.5 are significant, they don’t extend beyond the walled garden that is iOS. Kint likens the immediate impact to squeezing one part of a water balloon: The liquid just expands to the other side. Platforms like Android and the web on most browsers will still allow tracking, and marketers may focus even more strongly there. But Apple’s step with ATT could ultimately spark broader change.

For now, though, just download iOS 14.5 if you have an iPhone, and get ready to start tapping “Ask App not to Track” whenever you see it. Especially in places you never saw coming.
