ClearGuard: AI Photo Cleaner (referred to as "the App", "we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and share information when you use our iOS application.

1. Information We Collect

1.1 Information You Provide Directly

The App does not require you to create an account or provide personal information to use its core features. However, we may collect:

• Contact information: If you contact our support team, we collect your email address and the content of your message.

1.2 Device and Usage Information

We automatically collect certain technical information when you use the App:

• Device identifiers:
  • IDFV (Identifier for Vendor) - a unique device identifier for this app
  • IDFA (Advertising Identifier) - only collected if you grant App Tracking Transparency (ATT) permission
  • Adjust Device ID (ADID) - generated by our analytics partner
• Device information: Device model, operating system version, language settings, and timezone
• App usage data: Features you use, actions you take within the app, session duration, and app version
• Subscription data: Purchase transaction IDs, subscription status, and product IDs (no payment card information is collected - all payments are processed by Apple)
• Crash and diagnostic data: Stack traces, error logs, and app performance metrics to identify and fix bugs

1.3 Local Device Data Access

The App requests permission to access the following data stored on your device. All processing happens locally on your device - we do not upload this data to our servers:

• Photo Library: To analyze and identify duplicate, similar, or low-quality photos and videos. Photos are processed on-device using computer vision algorithms.
• Contacts: To identify duplicate or incomplete contact entries. Contact data is analyzed locally and not transmitted.
• Calendar: To identify and help clean expired calendar events. Calendar data remains on your device.

1.4 Biometric Data

If you enable the Private Space feature, the App uses Face ID or Touch ID to authenticate access. Biometric data is processed by iOS and never leaves your device or becomes accessible to us.

2. How We Use Your Information

We use the collected information for the following purposes:

2.1 To Provide and Improve the App

• Enable core features (photo analysis, duplicate detection, storage optimization)
• Analyze usage patterns to improve app performance and user experience
• Debug crashes and fix technical issues
• Develop new features based on how users interact with the app

2.2 To Manage Subscriptions

• Verify subscription status and entitlements
• Process refunds and billing issues
• Prevent subscription fraud and abuse
• Analyze subscription retention and churn patterns

2.3 For Marketing Attribution and Analytics

3. Third-Party Services and Data Sharing

We use the following third-party services that may collect or process your data:

3.4 Apple App Store

When you purchase a subscription, your payment information is processed by Apple. We receive only the transaction ID and subscription status - we never have access to your credit card or payment details.

4. Data Storage and Security

4.1 Local Storage

The following data is stored on your device:

• Subscription status cache (to improve app launch time)
• Analysis results (duplicate photos, similar photos) to avoid re-processing
• App preferences and settings

Device identifiers, subscription events, and attribution data are stored on our secure servers using industry-standard security measures:

• Data transmission is encrypted using TLS 1.3
• Servers are protected by firewalls and intrusion detection systems
• Access to our systems is restricted to authorized personnel only
• We use AES-256 encryption for data at rest

4.3 Data Retention

• Active subscriptions: Data is retained as long as your subscription is active

• Device data: If you do not use the app for 24 months, associated device data is automatically purged
• Support emails: Retained for 24 months, then deleted
