Advertising ID reset capability provided

Apple's App Tracking Transparency (ATT) framework, introduced in iOS 14.5, requires explicit user authorization before an app can access the Identifier for Advertisers (IDFA) and use it for cross-app tracking. GDPR Art. 7(3) and CCPA §1798.120 extend this right to reset or limit tracking to all users in regulated regions. An app that displays ads but provides no mechanism for users to reset their advertising ID or access ad preference settings treats the user as a passive tracking target with no control. Google Play Data Safety requires disclosure of advertising ID usage; apps that collect it without providing reset capability face Data Safety accuracy flags. Apple ATT compliance is enforced at the SDK layer — ad SDKs that bypass ATT face App Store removal.

For iOS, request ATT authorization before initializing any ad SDK. Provide a Settings link to Apple's advertising preference panel for users who want to reset or limit tracking.

import { Platform, Linking } from 'react-native'
import { requestTrackingPermissionsAsync } from 'expo-tracking-transparency'

// iOS: Request ATT before initializing ad SDK
async function initializeAds() {
  if (Platform.OS === 'ios') {
    const { status } = await requestTrackingPermissionsAsync()
    if (status !== 'granted') {
      // Initialize ad SDK in limited-tracking mode
      AdSDK.init({ limitTracking: true })
      return
    }
  }
  AdSDK.init({ limitTracking: false })
}

// Settings screen: link to platform ad preferences
function openAdSettings() {
  const url = Platform.OS === 'ios'
    ? 'app-settings://'
    : 'https://adssettings.google.com'
  Linking.openURL(url)
}

Add the ATT usage description to app.json: "NSUserTrackingUsageDescription": "This allows us to show you more relevant ads".
