Effective October 7, 2026
Privacy Policy
This policy explains how the Pheng Shui app for iPhone handles your information. The short version: the developer collects no data. Your photos and everything the app stores stay on your device.
No data collected
Pheng Shui does not collect, store or share any personal data with the developer or anyone else. The app has:
- No account and no sign-in
- No analytics and no crash reporting by the developer
- No ads and no tracking
- No third-party SDKs
The app does not run its own servers. Nothing you do in the app is sent to the developer.
Photo access
Pheng Shui asks for access to your photo library so it can show, sort and delete the photos you choose. You decide whether to grant full or limited access, and you can change this at any time in Settings → Pheng Shui → Photos.
Your photos are processed only on your device. They never leave it and are never uploaded by the app. If you use iCloud Photos, iOS may download a full-size original from your own iCloud library when the app needs it. That transfer is handled by Apple between your device and your iCloud account.
Duplicate detection
Finding similar photos runs entirely on your device. The app compares small visual fingerprints of your photos locally. No photo, fingerprint or result is sent anywhere.
Data stored on your device
To remember where you left off, the app saves the following locally on your device only:
- Sorting progress
- Your list of photos marked for deletion
- Simple statistics, such as the number of photos sorted and deleted
- Duplicate scan results
- Your app settings
This data is not sent to the developer. It is removed when you delete the app.
Deleting photos
Photos are deleted only after you confirm, using the standard iOS Photos deletion flow. Deleted photos move to the Recently Deleted album in the Photos app, where you can recover them for up to 30 days.
Pheng Shui Pro
Pheng Shui Pro is a one-time in-app purchase. The purchase is processed entirely by Apple through the App Store. The developer does not receive your name, payment details or Apple Account information. Purchases can be restored on devices signed in with the same Apple Account.
Apple's handling of purchases is covered by Apple's Privacy Policy.
