One of the reasons why the update to iOS 14.5 is so eagerly awaited is the AppTrackingTransparency (ATT) feature. A box will appear on the screen with a message from a third-party app asking an iPhone user for permission to continue tracking him/her in order to send online ads. By default, the iPhone user withholds permission to be tracked across the internet by a third party app. Besides iOS 14.5, the ATT feature will also be found on the iPad with iPadOS 14.5, and with tvOS 14.5.
Apple reminds app developers that the AppTrackingTransparency feature is coming soon with iOS 14.5
For example, yours truly plans on giving permission to be tracked by third party apps. That’s because unlike most users, this writer considers it convenient to receive third party ads. And permission can always be withdrawn if so desired.
Developers also need to understand that it remains a violation of the App Store to collect device and usage data in an attempt to create the profile of a user to determine his/her identity. In fact, that violates the Apple Developer Program License Agreement. Speaking of this agreement, Apple recently cited it for the reason to reject several new apps. In its letter to rejected developers, Apple said, “We found in our review that your app collects user and device information to create a unique identifier for the user’s devices. Apps that fingerprint the user’s device in this way are in violation of the Apple Developer Program License Agreement and are not appropriate for the App Store.”
