Mobile App Privacy Policy Guide
App Store and Google Play compliance guide
Mobile apps face unique privacy requirements from both app stores and privacy regulations. This guide covers Apple's App Store requirements, Google Play requirements, device permissions disclosure, and how to properly document your data collection practices.
App Store Requirements
Apple App Store (iOS)
Apple requires all apps to submit privacy information through App Store Connect. This information is displayed on your app's product page.
Data Types to Declare
- Contact Info: Names, phone numbers, email addresses
- Identifiers: Device IDs, user IDs
- Usage Data: Product interaction, analytics
- Diagnostics: Crash logs, performance data
- Location: Precise location, approximate location
- Sensitive Info: Health data, financial info, biometrics
- Contacts: Contact information from device
- Photos or Videos: Media library access
- Audio: Audio recordings
- Gameplay Content: Gameplay data, scores
- Browsing History: Web browsing data
- Search History: Search queries
- Purchases: Purchase history
- Coarse Location: Approximate location
App Tracking Transparency
Since iOS 14.5, apps must request permission before tracking users across other companies' apps and websites. You must:
- Implement the App Tracking Transparency framework
- Present a prompt explaining why you're tracking (or not track)
- Respect the user's choice
- Only enable tracking if the user authorizes it
Google Play (Android)
Google requires apps to complete a Data Safety section in the Google Play Console.
Data Safety Requirements
- Declare what data your app collects
- Explain how data is shared and secured
- Identify if data is encrypted in transit
- State if users can request deletion
- Provide target audience and age rating
- Link to your full privacy policy
Google Play Enforcement
Google Play has strict enforcement:
- Apps without privacy policies may be removed
- Misleading data declarations can result in violations
- Apps must be honest about data collection
- SDKs must also comply with policies
Data Collection Disclosure
Your privacy policy must clearly explain what data you collect:
Data You Collect
- Account information (name, email, phone)
- Profile information (photos, bio, preferences)
- Payment and transaction data
- Location data (precise or approximate)
- Device information (type, OS version, ID)
- Usage data and analytics
- Communications (messages, support tickets)
- Content you create or upload
How You Use Data
- Provide core app functionality
- Personalize user experience
- Process transactions and payments
- Send notifications and updates
- Improve and develop the app
- Prevent fraud and ensure security
- Comply with legal obligations
- Marketing and advertising (with consent)
Third-Party Sharing
- Analytics providers (Google Analytics, Firebase)
- Advertising networks (AdMob, Facebook Ads)
- Payment processors (Stripe, PayPal)
- Customer support tools (Zendesk, Intercom)
- Cloud services (AWS, Firebase)
- Social media platforms (if social features)
- Legal authorities (if required)
Data Retention
- Account data retained while account active
- Delete upon account deletion or request
- Logs retained for limited periods
- Legal holds may extend retention
- Backups deleted within defined periods
- Anonymized data may be retained longer
Children's Privacy (COPPA)
If your app targets children under 13 (or 16 in some jurisdictions), you must comply with COPPA. This includes restricting data collection, obtaining verifiable parental consent, and not using children's data for behavioral advertising.
Privacy Labels & Nutrition Labels
Both Apple and Google display privacy information directly in the app stores:
Apple Privacy Nutrition Labels
App Store displays privacy labels in three categories:
Data Used to Track You
Lists data linked to users across other companies' apps/websites
Data Linked to You
Data that may be linked to user identity
Data Not Linked to You
Data that cannot be linked to user identity
Complete these labels accurately in App Store Connect. Apple may reject apps with inaccurate privacy information.
Google Play Data Safety Section
Google Play requires a Data Safety form with these elements:
- Is data collected?
- Why is data collected?
- Is data encrypted?
- Can users delete data?
- Target audience age rating
- Link to privacy policy
- Security practices disclosure
Google may remove apps that don't complete this section or provide misleading information.
Third-Party SDKs & Libraries
Your app likely uses SDKs that collect data. You're responsible for disclosing their practices:
Analytics SDKs
Google Analytics, Firebase Analytics, Amplitude, Mixpanel
Collect device info, usage patterns, events. Review each SDK's privacy policy and declare their data collection.
Advertising SDKs
Google AdMob, Facebook Audience Network, Unity Ads, AppLovin
Collect identifiers, location, usage data for ad targeting. Implement consent mechanisms where required.
Crash Reporting
Firebase Crashlytics, Bugsnag, Sentry
Collect device info, crash logs, stack traces. Usually considered diagnostic data.
Authentication
Firebase Auth, Auth0, AWS Cognito
Collect email, phone, identity data for authentication purposes.
Push Notifications
Firebase Cloud Messaging, OneSignal
Collect device tokens for notification delivery. May collect engagement data.
Social SDKs
Facebook SDK, Twitter SDK, LinkedIn SDK
May collect data for login, sharing, and social features. Review each provider's data practices.
SDK Responsibility
You're ultimately responsible for what's in your app, even if an SDK collects data. Maintain a current list of all SDKs and their data practices, and include them in your disclosure.
GDPR Compliance for Mobile Apps
If your app has EU users, GDPR applies. Key requirements:
Consent
Obtain clear, informed consent before collecting non-essential data. Consent must be freely given, specific, informed, and unambiguous.
Privacy by Design
Build privacy into your app from the start. Minimize data collection, use encryption, and provide user controls.
Data Subject Rights
Enable users to access, correct, delete, and port their data. Respond within 30 days.
International Transfers
If using servers outside the EU, disclose transfer mechanisms (SCCs, adequacy decisions) and ensure adequate protection.
CCPA/CPRA for Mobile Apps
California users have specific rights under CCPA/CPRA:
- Right to Know: Disclose all data collected, sources, purposes
- Right to Delete: Delete personal information upon request
- Right to Opt-Out: Allow opt-out of data sale/sharing
- Right to Correct: Allow correction of inaccurate data
- Limit Use of Sensitive Data: Get consent for sensitive data use
- Non-Discrimination: Don't penalize for exercising rights
Mobile App Considerations
Mobile apps often collect more data than websites, increasing CCPA relevance. Device identifiers, location data, usage patterns, and in-app behavior all count as personal information under CCPA.
