Privacy Policy for Mobile Apps: Requirements for iOS and Android

Why Mobile Apps Need a Privacy Policy

Mobile applications collect more personal data than most users realize. Beyond the information users explicitly provide (names, emails, preferences), apps can access device identifiers, location data, contacts, photos, camera, microphone, and browsing activity. Both Apple and Google require privacy policies for all apps distributed through their stores, and failing to provide one will result in rejection during app review or removal from the store.

Privacy laws like GDPR, CCPA, and COPPA also apply to mobile apps. Since apps often collect more sensitive data than websites (like precise GPS location or health data), the compliance stakes are higher.

Apple App Store Requirements

Privacy Policy Requirement

Apple requires all apps submitted to the App Store to include a privacy policy URL. This has been mandatory since October 2018. The policy must be accessible at the URL you provide in App Store Connect, available both within the app and on the App Store listing, and written in a way that clearly explains what data the app collects and how it is used.

App Privacy Labels (Nutrition Labels)

Since December 2020, Apple requires developers to fill out App Privacy Labels that appear on the App Store listing. These labels disclose data used to track users across apps and websites owned by other companies, data linked to the user's identity, and data not linked to the user's identity. Your privacy policy must be consistent with your App Privacy Labels. If your label says you do not collect location data but your app requests location permission, Apple will flag the inconsistency.

App Tracking Transparency (ATT)

Since iOS 14.5, apps must use Apple's App Tracking Transparency framework to request permission before tracking users across apps and websites. "Tracking" includes sharing user data with data brokers, using device advertising identifiers for targeted advertising, and linking user or device data with data from other companies. Your mobile app privacy policy should explain your tracking practices and how ATT affects the user experience.

Google Play Requirements

Privacy Policy Requirement

Google Play requires a privacy policy for all apps that handle personal or sensitive user data. This includes apps that access device permissions (camera, location, contacts, etc.), apps that collect personal information, and apps that use third-party SDKs that collect data. The privacy policy URL must be provided in the Google Play Console and must be accessible without any login requirement.

Data Safety Section

Google Play's Data Safety section requires developers to disclose what data is collected and shared, whether data is encrypted in transit, whether users can request data deletion, and whether the app follows Google's Families policy (if applicable). Like Apple's privacy labels, your Data Safety section must match your actual data practices and your privacy policy.

Permissions and Data Access

Google Play requires that apps only request permissions they actually need. Your privacy policy should explain why each permission is requested. If your photo editing app requests location permission, you need a good reason and must disclose it.

What Your App Privacy Policy Should Include

Data Collection Details

Mobile apps typically collect several categories of data. Be specific about each. Account information includes names, emails, passwords, and profile pictures. Device information includes device model, operating system version, unique device identifiers, and mobile network information. Location data includes GPS, IP-based location, Wi-Fi, and Bluetooth signals. Usage data includes features used, session times, in-app actions, and crash data. Media includes photos, videos, or audio accessed or stored by the app. Contacts include address book data if the app requests contact access. Financial data includes payment information, purchase history, and subscription details.

SDKs and Third-Party Libraries

Mobile apps commonly include third-party SDKs that collect their own data. Common examples include Firebase (Google) for analytics and crash reporting, Facebook SDK for authentication and advertising, Adjust, AppsFlyer, or Branch for attribution, Stripe or RevenueCat for payments, OneSignal or Firebase Cloud Messaging for push notifications, and Crashlytics or Sentry for crash reporting. Each SDK has its own data collection practices. Your privacy policy should identify the major categories of SDKs you use and link to their privacy policies.

Push Notifications

If your app sends push notifications, explain what types of notifications users will receive, how to opt in and out (both within the app and through device settings), and whether you use notification data for any purpose (like measuring engagement).

In-App Purchases and Subscriptions

If your app includes in-app purchases or subscriptions, disclose how payment information is handled. In most cases, Apple or Google handles the actual payment processing, but you may still receive certain transaction data.

Children's Privacy (COPPA)

If your app is directed at children under 13 (or under 16 in the EU), you must comply with COPPA (Children's Online Privacy Protection Act) and similar laws. This means obtaining verifiable parental consent before collecting data from children, limiting data collection to what is necessary for the app's functionality, not using behavioral advertising, and not using persistent identifiers for tracking. Both Apple and Google have additional policies for apps in the Kids category. Your privacy policy must address children's privacy if your app could attract users under the age thresholds.

Terms of Service for Mobile Apps

Beyond a privacy policy, your mobile app also needs Terms of Service that cover license grants, acceptable use, in-app purchase terms, and platform-specific requirements from Apple and Google.

Where to Display Your Privacy Policy

Your privacy policy should be accessible in the app store listing (required by both Apple and Google), within the app itself (typically in Settings or About), on your website, during onboarding or account creation, and before requesting sensitive permissions. Making the policy accessible within the app is important because users should not need internet access to review it after downloading.

Updates and Version History

Mobile apps update frequently, and each update can change data collection practices. When you add new SDKs, request new permissions, or change how data is processed, update your privacy policy accordingly. Include a "Last Updated" date and consider maintaining a version history so users can see what changed.
