Correct user consent flow for compliance with GDPR and ATT requirements using Firebase Analytics and AdMob

Question

My team & I have been banging our heads against the wall lately. We’re working on an app and are utilising Firebase Analytics and AdMob.

We’re trying to ensure/confirm that our user consent flow when opening the app the first time complies with GDPR and iOS's App Tracking Transparency requirements. We designed a flowchart (see image attached), based on our research.

Breakdown of the flowchart:

1. App Launch
2. Firebase analytics consent form:
   • A consent form is displayed asking if the user agrees to data collection for analytics purposes.
     • Also privacy policy and terms of service would be linked
   • Options:
     • Accept -> enables data collection
     • Decline -> disables data collection
3. AdMob personalised ads consent form:
   • Another consent form for personalised advertisements.
   • Options:
     • Accept -> allows personalised ads on android, green light for the next step (4) on ios
     • Decline -> disallows personalised ads
4. ATT Prompt (for iOS users, if personalised ads are accepted):
   • Shows the iOS ATT prompt to request permission to track the user across apps and websites owned by other companies.
   • Options:
     • Allow -> allows personalised ads on iOS
     • Don't Allow -> disallows personalised ads
5. Redirect to home screen🎉

We would appreciate feedback on following questions:

Would this flow meet GDPR & ATT requirements?

Is the ATT prompt correctly placed? Only after obtaining consent for personalised ads?

Any improvements/suggestions to better align with privacy regulations?
