Your photos never leave your device. All scanning, comparison, and duplicate detection happens entirely on your device. We do not collect, upload, transmit, or sell your photos.
1. Overview
LynxApps ("we," "us," "our") operates the Duplicate Photo Finder application ("App"). This Privacy Policy explains how we handle your information when you use the App. We are committed to protecting your privacy — your photos are processed only on your device using on-device AI technology.
2. Information We Collect
Photo & Video Data
The App accesses your photo library to detect duplicate and similar photos, analyze metadata (resolution, quality, format), and provide intelligent recommendations.
Important: All processing happens locally on your device. Your photos are never uploaded, transmitted, or stored on our servers.
Device & Usage Information
Through third-party services, we automatically collect:
- Device model and operating system version
- App usage data and performance metrics
- Crash reports and error logs
- Advertising identifier (for personalized ads)
Subscription & Payment Information
All in-app purchases are processed through Apple's App Store (iOS) or Google Play Billing (Android), depending on which version of the App you use. We do not collect or store payment card information. We receive only purchase confirmation, subscription status, and receipt information.
