Cross-Platform Privacy Policies for iOS & Android with Expo SDK & Firebase Compliance
One codebase. Two app stores. Two completely different sets of privacy requirements. Here is what makes React Native compliance uniquely complex.
React Native's "write once, run anywhere" means your privacy policy must satisfy both Apple App Store and Google Play Store requirements simultaneously. Each store has different review criteria, data disclosure formats, and compliance expectations.
iOS uses NSUsageDescription strings and the ATT framework. Android uses dangerous permissions and runtime permission requests. Your policy must explain both permission models even though your code handles them through a single React Native API.
Data passes between JavaScript and native layers via the bridge. This architecture means data collection patterns differ from pure native apps. Your policy needs to explain how data moves between JS and native modules on each platform.
Expo EAS Update and CodePush let you push code changes without store review. If an OTA update changes data collection, your privacy policy must be updated immediately and users notified in-app — before the store even knows about the change.
Your React Native privacy policy must address platform-specific requirements. Here is how iOS and Android differ on every major privacy concern.
| Category | iOS (App Store) | Android (Play Store) |
|---|---|---|
| App Tracking | ATT framework required. Must show tracking permission dialog before accessing IDFA. | Google Advertising ID (GAID) available by default. User can opt out in device settings. |
| Privacy Labels | Privacy Nutrition Labels in App Store Connect. Must declare all data types collected. | Data Safety section in Play Console. Must declare data collection, sharing, and security. |
| Location Access | NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription required. | ACCESS_FINE_LOCATION, ACCESS_COARSE_LOCATION, ACCESS_BACKGROUND_LOCATION permissions. |
| Push Notifications | Automatic system prompt. Expo Notifications or APNS direct. | POST_NOTIFICATIONS permission (Android 13+). FCM or Expo push service. |
| Camera/Photos | NSCameraUsageDescription, NSPhotoLibraryUsageDescription strings mandatory. | CAMERA and READ_MEDIA_IMAGES permissions. Scoped storage on Android 10+. |
| Data Deletion | Account deletion required since June 2022 for apps with account creation. | Data deletion option required in Play Console since December 2023. |
PolicyForge generates a single policy that satisfies both columns — no manual reconciliation needed.
Every npm package that touches native APIs collects data. Your privacy policy must disclose each one. Here are the most common React Native modules and what they require.
Data collected: GPS coordinates, altitude, speed, heading. Background location if enabled.
Required disclosure: Must explain foreground vs background tracking, data frequency, and third-party sharing.
Data collected: Photos, videos, camera metadata (EXIF data including location if embedded).
Required disclosure: Explain if media is uploaded to servers, stored locally, or processed by third-party AI.
Data collected: Push tokens stored on Expo infrastructure. Notification interaction analytics.
Required disclosure: Disclose Expo's role as a third-party processor and link to Expo's privacy policy.
Data collected: Names, phone numbers, emails, addresses from device contacts.
Required disclosure: Explain purpose, whether contacts are uploaded to servers, and data retention.
Data collected: Encrypted key-value data stored in iOS Keychain / Android Keystore.
Required disclosure: Explain what sensitive data is stored (tokens, credentials) and encryption method.
Data collected: Events, user properties, device info. IDFA on iOS, GAID on Android.
Required disclosure: Platform-specific identifier disclosure. Link to Google Firebase privacy policy.
Data collected: Crash logs, stack traces, device state, OS version, app version.
Required disclosure: Explain automated crash reporting and what device info is sent to Google.
Data collected: Error reports, breadcrumbs, device context, user sessions.
Required disclosure: Disclose Sentry as a processor, what context data is captured, and data retention.
