Apple’s crusade to tighten privacy in its App Store is shifting into another gear. The company is cracking down on developers who use a technique called device fingerprinting to track user activity – even if they’ve opted out.

Specifically, the company wants devs to explain why they’re using certain application programming interfaces (APIs) and third-party software development kits (SDKs) in their apps. As part of its app store review process, it is also requiring developers to update their privacy documentation.

Those who fail to comply could find their apps denied approval in the App Store. 

Apple’s introduction of the Vision Pro mixed reality headset at its Worldwide Developers Conference last week has already touched off raging debates over how many units the company will sell.

To be frank, focusing on unit sales misses the point. The reality is the world isn’t ready for a $3,500 USD sci-fi-esque headset, and it’ll take years for consumers to buy into a class of technology most of them are still trying to understand.

But no one ever said transitioning away from smartphones and into whatever else comes next was going to be easy. And if any single organization can power this generational shift, it’s Apple.

It’s easy to understand why most of us might not have immediately dropped everything to update our iPhones, iPads, and Macs after Apple recently confirmed that researchers had helped uncover a serious vulnerability in the operating systems that power its devices.
