Is iOS14.5 ATT prompt enforcement device agnostic ?

For example : If user A opts out of ATT prompt when it is shown on their iOS device, is it ok for the app developer to exchange data associated with this user's activity on their website and or other websites that originate on the user's desktop ?

Stated differently, is the app required to respect the ATT opt out across their iOS app, website, android app or the enforcement is limited at the user x device level ?

From the FAQ on this page:

If a user provides permission for tracking via a separate process on our website, but declines permission in the app tracking transparency prompt, can I track that user across apps and websites owned by other companies?

Developers must get permission via the app tracking transparency prompt for data that’s collected in the app and used for tracking. Data collected separately, outside of the app and not related to the app, is not in scope.

That said, there’s also this:

If tracking occurs within a webview inside an app, do I need to use the AppTrackingTransparency prompt?

Yes. If you are using a webview for app functionality, it should be treated the same way as native functionality in your app, unless you are enabling the user to navigate the open web.
