iOS App Tracking Transparency (ATT)
iOS 14+ requires apps that track users across other companies' apps and websites — including AdMob personalized ads — to ask for permission via the system ATT dialog. Without it: ads degrade to non-personalized, eCPM drops dramatically, and Apple rejects the build during review.
When to consult
Hard rules
- ❌ NEVER prompt on first launch. Apple rejects this. The ATT dialog must come after the user has experienced enough of the app to understand why permission is being requested.
- ✅ Prompt after onboarding completes and before AdMob's first impression.
- ✅ The
NSUserTrackingUsageDescription string in Info.plist MUST clearly state how the data is used. Generic placeholders ("We need this to show ads") get rejected.
- ✅ Android is not affected — the ATT plugin no-ops on Android.
- ✅ ATT pairs with
ionic-cmp-consent — they cover different jurisdictions (Apple vs EU), and both are required for full ad revenue.
