As of iOS 14.5, Apple requires publishers to request user consent for marketing tracking by default. However, does Apple apply this rule to itself? No, but you can turn this option off.

For several months, Apple has been the subject of complaints for antitrust practice. Recently, it was the Spanish association Spain Digitale which lodged a complaint with the CNIL (National Commission for Informatics and Freedoms) for violation of the rules of the European Union vis-à-vis confidentiality and rules governing competition. Apple would not be held to the same requirements as other application developers when it comes to privacy and the handling of user tracking data.
As a reminder, the next version of iOS (14.5) will force developers to obtain the explicit consent of their users in order to be able to track them and share the data collected with third-party advertising networks. As we have seen, Apple does not follow its own rules.
Indeed, Apple is also a commercial agency which sells various advertising spaces to advertisers. You have advertisements, for example, on the App Store. Apple is authorized by default to use the data collected on its users from its own applications in order to display targeted advertisements.
How do I turn off targeted advertising from Apple?
It's relatively simple, it requires 3 clicks. Go to iOS settings, then to Privacy.
Click on Confidentiality
Once in Privacy, scroll to the bottom of the menu and look for Apple Advertising.
At the bottom, there is Apple Advertising
You just have to deactivate the targeted advertisements by unchecking the Targeted advertisements option.
