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

Device Permissions

Mobile apps commonly request various device permissions. Each requires disclosure:

Camera

Used for: Taking photos, recording videos, video calls, barcode scanning

Disclosure: Explain why you need camera access and what you do with captured media. Note if photos are stored locally or uploaded to servers.

Microphone

Used for: Voice recording, voice commands, video recording with audio

Disclosure: State what audio is recorded, how long it's retained, and whether it's sent to servers or processed on-device.

Location

Used for: Navigation, location-based features, geo-tagging, proximity features

Disclosure: Distinguish between precise (GPS) and approximate (network-based) location. Explain if location is tracked continuously or only when using specific features.

Contacts

Used for: Finding friends, referrals, contact syncing

Disclosure: Explain what contact data is accessed, how it's used, whether it's stored, and if it's shared with third parties.

Photos/Media

Used for: Saving images, accessing photo library, uploading media

Disclosure: Specify which photos are accessed, whether you can read or write, and how media is processed.

Bluetooth

Used for: Connecting to devices, peer-to-peer features, beacons

Disclosure: Explain device pairing purposes and any data exchanged via Bluetooth.

Notifications

Used for: Push notifications, reminders, updates

Disclosure: Note types of notifications sent and whether they can be disabled.

Device ID & Call Info

Used for: Analytics, fraud prevention, user identification

Disclosure: Explain what identifiers are collected (Advertising ID, device ID), why they're used, and how long they're retained.

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.
