Implementing App Tracking Transparency

1. Installing Tracking Module

Example: Install AppTrackingTransparency

npm install expo-apple-ads-tracking

Property	Description	Values
expo-apple-ads-tracking	Module for handling App Tracking Transparency on iOS	`latest`

Note: Requires iOS 14+ and appropriate permissions to function.

2. Requesting Tracking Permission

Permission	Status	Description
APP_TRACKING_TRANSPARENCY	NEW	Required for accessing app tracking transparency API

Example: Requesting Permission

import { request, PERMISSIONS } from 'react-native-permissions';

const requestTrackingPermission = async () => {
  const result = await request(PERMISSIONS.ANDROID.APP_TRACKING_TRANSPARENCY);
  console.log('Permission result:', result);
};

Note: On iOS, the user must have granted permission for tracking before the app can access the IDFA.

3. Getting Tracking Status

Example: Check tracking authorization status

import { getTrackingStatus } from &#x27;expo-tracking&#x27;;

const status = await getTrackingStatus();
console.log(status); // "authorized", "denied", "not-determined"

Return Value	Description	Notes
authorized	User has granted permission	Tracking is allowed
denied	User has denied permission	Tracking is disabled
not-determined	User has not yet made a choice	Can request permission

Note: On iOS, this requires the NSUserTrackingUsageDescription in your app.json.

4. Handling Permission Response

Property	Description	Values
status	Current permission status	`granted`, `denied`, `not-determined`, `restricted`
canAskAgain	Indicates if the user can be asked again for permission	`true`, `false`

Example: Check and handle permission response

import { request, PERMISSIONS, RESULTS } from 'react-native-permissions';

const handleTrackingPermission = async () => {
  const result = await request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY);
  
  switch (result) {
    case RESULTS.GRANTED:
      console.log('Tracking permission granted');
      break;
    case RESULTS.DENIED:
      console.log('Tracking permission denied');
      break;
    case RESULTS.UNAVAILABLE:
      console.log('Tracking permission not available');
      break;
  }
};

5. Configuring Info.plist

Property	Value	Description
NSUserTrackingUsageDescription	`"This app uses tracking to personalize your experience."`	Explanation shown to user when requesting tracking permission

Example: Info.plist Configuration

<key>NSUserTrackingUsageDescription</key>
&lt<string>This app uses tracking to personalize your experience.</string>

6. Implementing Permission Flow

Example: Requesting App Tracking Transparency Permission

import { request, PERMISSIONS, RESULTS } from 'react-native-permissions';

const requestTrackingPermission = async () => {
  const result = await request(PERMISSIONS.ANDROID.APP_TRACKING_PERMISSION);
  console.log('Permission result:', result);
};

requestTrackingPermission();

Permission	Status	Description
APP_TRACKING_PERMISSION	NEW Android 13+	Permission to access app tracking information

Note: On Android 13+, users must explicitly grant the App Tracking Permission for tracking features to work.

Warning: If the permission is denied, tracking features may not function as expected.

7. Handling Denied Permission

Example: Check and handle denied permission

import { request, PERMISSIONS, RESULTS } from 'react-native-permissions';

const handleTrackingPermission = async () => {
  const result = await request(PERMISSIONS.IOS.APP_TRACKING_TRANSPARENCY);

  switch (result) {
    case RESULTS.DENIED:
      // User denied permission, show rationale or alternative
      console.log('Tracking permission denied');
      break;
    case RESULTS.BLOCKED:
      // User has blocked the permission, guide to settings
      console.log('Tracking permission blocked');
      break;
    case RESULTS.GRANTED:
      // Permission granted, proceed with tracking
      console.log('Tracking permission granted');
      break;
  }
};

Result	Description	Action
DENIED	User denied the permission request	Inform user and provide rationale or alternative actions
BLOCKED	User has blocked the permission, cannot request again	Guide user to settings to enable permission
GRANTED	User has granted the permission	Proceed with tracking logic

Note: When permission is blocked, users must manually enable it in their device settings.

Warning: If tracking is essential for your app's functionality, ensure you provide clear user guidance when permissions are denied or blocked.

8. Using IDFA

Property	Description	Values	Notes
idfa	Identifier for Advertiser	`null` or `string`	Used for tracking purposes in advertising
limitAdTracking	Flag to limit ad tracking	`true` or `false`	When set to true, limits ad tracking

Example: Requesting IDFA

import { requestTrackingAuthorization } from 'expo-tracking';

const idfa = await requestTrackingAuthorization();
console.log(idfa);

Note: The IDFA is only accessible after the user has granted tracking authorization.

9. Checking ATT Availability

Property	Description	Availability
requestTrackingAuthorization	Method to request tracking authorization from the user	NEW in Expo SDK 50
trackingStatus	Current tracking status of the app	Available in Expo SDK 50+

Example: Checking ATT Availability

import { requestTrackingAuthorization, trackingStatus } from 'expo-tracking';&#10;&#10;const checkATT = async () => {&#10;  const status = await trackingStatus();&#10;  console.log('Current tracking status:', status);&#10;&#10;  if (status === 'not-determined') {&#10;    const authStatus = await requestTrackingAuthorization();&#10;    console.log('Requested authorization:', authStatus);&#10;  }&#10;};

Note: The requestTrackingAuthorization method is only available on iOS devices running iOS 14 or later.

10. Implementing Privacy Labels

Example: Privacy Labels Configuration

{
  "expo": {
    "privacyLabels": {
      "analytics": "Yes",
      "crashReporting": "Yes",
      "dataCollection": "Yes"
    }
  }
}

Label	Value	Description
analytics	`Yes`	Indicates if the app collects analytics data
crashReporting	`Yes`	Indicates if the app reports crashes
dataCollection	`Yes`	Indicates if the app collects user data

Note: Privacy labels are required for apps distributed on the App Store and Google Play.
