Apple set to release long-awaited iOS update to restrict tracking by advertisers

Apple is about to give millions of iPhone users a choice: Allow Facebook and other apps running on Apple's iOS platform to track your activity on your phone and online, or stop tracking altogether.

What will you choose? Among the new features in Apple's new iPhone software, iOS 14.5, is a major privacy update called App Tracking Transparency, which requires apps to request permission before gathering user or device data. Specifically, the update changes the Identifier for Advertisers (IDFA), a unique, random number assigned to each iPhone that allows advertisers and developers to track user behavior, including app usage and web browsing behavior. The IDFA is often used to personalize advertisements.
