Introduction
Welcome to PhotoTrans. We deeply respect and protect your privacy. This privacy policy explains how we handle your information when you use our application.
Core Privacy Commitment
PhotoTrans processes all your photos entirely on your device. We do not upload, store, or access your photos in any way.
1. Information We Collect
PhotoTrans does not collect any personal information or photo data.
Specifically:
- We do not collect your name, email address, or any contact information
- We do not access, upload, or store your photos
- We do not collect your device identifiers (UDID, MAC address, etc.)
- We do not use any tracking technologies (cookies, analytics, etc.)
- We do not collect location information
2. How We Process Photos
PhotoTrans's core philosophy is "100% On-Device Processing":
- Local Processing: All AI processing happens entirely on your iPhone using Core ML technology
- No Upload: Your photos never leave your device, not even temporarily
- No Cloud: We do not use any cloud services or servers
- Offline Operation: The app works completely offline, no internet connection required
3. Photo Library Access
PhotoTrans requires access to your Photo Library to:
- Select Photos: Allow you to choose photos for processing
- Save Results: Save processed photos back to your Photo Library
Important Notes:
- Photo Library access is controlled entirely by iOS system permissions
- You can grant or revoke this permission at any time in Settings
- We only access photos you explicitly select, never your entire library
- Accessed photos are only processed locally, never transmitted
4. Data Storage and Security
Since PhotoTrans doesn't collect any data, there's nothing to store or secure. However:
- Temporary Files: During processing, temporary files may be created on your device. These are automatically deleted after processing
- App Settings: Your app preferences are stored locally on your device only
- Processed Photos: Saved to your Photo Library, managed by iOS's secure storage system
5. Third-Party Services

6. Children's Privacy
PhotoTrans is suitable for users of all ages. Since we don't collect any personal information, there are no special considerations for children's privacy. However, we recommend that parents supervise children's use of the app.
7. Your Rights
Since we don't collect any of your data, there's no data to access, modify, or delete. You have complete control over:
- App Permissions: Manage Photo Library access in iOS Settings
- Processed Photos: Delete from your Photo Library at any time
- App Data: Uninstalling the app removes all app-related files
8. International Users
