Privacy Policy

Qingsao (轻扫) is a tool for organizing photos locally on your iPhone. Photo processing and similar-photo analysis take place on your device. We do not upload your photos, automatically collect personal data, require an account, or integrate third-party analytics or advertising.

1. Developer and scope

This policy applies to the Qingsao (轻扫) app developed by Digital Rabbit Technology Service and to this privacy policy webpage. Contact email: support@digitalrabbit.app.

2. Photo library access and photo processing

Qingsao uses Apple PhotoKit to access photos and necessary photo information within the scope of your permission, for browsing, jumping to a date, filtering screenshots, displaying Live Photos, and organizing your photo library. Similar-photo detection uses Apple Vision to process photo thumbnails and generate features for comparison on your device. Photos, thumbnails, features, and detection results are not uploaded to our servers or third-party analytics services.

Actions such as adding or removing favorites and deleting photos are performed through the system photo library APIs. You can change or revoke photo library access at any time in iOS Settings. Restricting access may make some features unavailable.

If you use iCloud Photos, Apple PhotoKit may download the required photos or thumbnails from iCloud according to your system settings. This is part of Apple’s photo library service and does not mean that Qingsao uploads photos to the developer. Apple’s privacy policy applies to this processing.

Only when you choose to open the details of a photo that contains a capture location does Qingsao use Apple’s reverse geocoding service to send the photo’s existing latitude and longitude to Apple to look up a city, district, street, or landmark name. This lookup does not upload photos, photo files, or similarity analysis results to Apple or the developer, and it does not access your device’s current location. The service requires a network connection and is subject to Apple’s privacy policy. If the lookup fails, the original latitude and longitude are displayed.

3. Local cache and progress

To improve performance and allow you to resume after an interruption, Qingsao stores necessary data locally on your device, including your browsing position, pending-deletion queue, photo identifiers, similarity analysis features, groups, and scan progress. This data is used only for app functionality, not to track users, and is not sent to us. When you uninstall the app, the system removes its local data. This does not delete photos in the system photo library.

Retrieved place names are cached locally by coordinates and system language to reduce repeated requests. Successful results are retained for up to 30 days, with a maximum of 128 entries. Failed results are retained only briefly in memory. The location cache is not sent to the developer.

4. Deletion requires your confirmation

Swiping up on a photo only adds it to the pending-deletion area, and you can undo this action. Similar-photo results and “Recommended to keep” provide organizational suggestions only; detection does not automatically delete photos. Qingsao asks the system photo library to delete photos only after you explicitly confirm clearing the queue. The system may ask for confirmation again. Recovery options and retention periods for deleted photos are determined by Apple’s Recently Deleted feature and your system settings.

5. Data collection, accounts, and third-party services

Qingsao requires no registration or sign-in, does not automatically collect personal data, does not use third-party analytics, advertising SDKs, or cross-app tracking, and does not sell or share your photos or analysis results.

If you voluntarily send feedback by email or TestFlight, we may receive the email address, text, screenshots, or diagnostic information you choose to send. We use these only to respond, troubleshoot issues, and improve the app. Please avoid sending unnecessary personal information in your feedback. Apple manages the transmission of TestFlight feedback and diagnostics, which is subject to Apple’s applicable policies.

Hosting and network providers, such as Vercel and Cloudflare, may process IP addresses and technical access logs to serve the webpage, provide security, and operate and maintain their services. This is separate from on-device photo processing in the app.

7. Your choices and how to contact us

You can adjust photo library permissions, undo pending photo deletions, or uninstall the app. If you have questions about this policy, feedback you have voluntarily submitted, or privacy matters, please contact support@digitalrabbit.app.

8. Policy updates

If features or data processing practices change, we will update this policy and the date above. If we introduce new data processing in the future, we will explain it to you and obtain the required authorization where applicable.
