ExifMate 隐私政策

1. Information We Collect

1.1 Information actively collected

None. The app does not collect any personal information, including but not limited to:

• No device information (model, hardware identifiers, advertising IDs, etc.);
• No location data;
• No personal data of any kind beyond the media files you choose to open (no contacts, messages, call logs);
• No account registration or sign-in;
• No advertising, analytics, or behavioral tracking components;
• No uploading of user content.

1.2 Data processed locally

The images/videos you open, and their metadata (EXIF tags, file names, timestamps), are processed only in the app's memory and on your local disk to deliver its core features (viewing, editing, restoration). This data never leaves your device. To support the "operation history & one-click restore" feature, the app keeps a local operation-history database (SQLite) — see Section 6.

1.3 Passively collected information

The app contains no networking code, so no passive data collection of any form exists (no cookies, web beacons, device fingerprinting, or telemetry).

2. Permissions

The app works through the file picker and accesses only the files and folders you actively choose to import:

• Access is limited to the paths you explicitly select in the file dialog; the app never scans other locations;
• The app does not request location, camera, microphone, contacts, calendar, or any other device/personal permissions;
• You can manage app permissions in system settings; restricting file access will affect core features.

3. How Information Is Used

The app collects no personal information, so none is used. The files you open and edit are used solely for the actions you initiate (view, compare, edit, rename, restore) and remain entirely on your device — never uploaded, transmitted, or synced anywhere.

4. Third-Party Components

The app is built on the following open-source components. Each performs only local computation inside this app — none performs network communication or collects data:

Full license texts ship with the app in the LICENSES/ folder and are also viewable in the in-app About page.

The app contains no advertising, analytics, push, social-sharing, or payment SDKs of any kind.

5. Information Sharing

• The app itself has no networking capability (see Sections 1 and 4);
• It connects to no cloud services;
• External links (open-source project websites, the store listing) in the About page or upgrade entry open in your system browser only when you click them; that is ordinary browser behavior and transmits no data from the app.

6. Data Storage Location and Retention

• Location: All data stays on your device. The only local data file is the operation-history database at %APPDATA%\ExifMate\exif.db (reachable via Settings → Open data folder). It records: paths and file names of processed files, before/after metadata snapshots, file hashes, and operation times — used solely for the operation-history & restore feature, for no other purpose.
• View & delete: You can inspect the file at any time; deleting it does not break the app, but you lose the ability to restore past operations.
• Uninstall: When you uninstall the app from Microsoft Store, this local data is removed along with the app's data. Back it up first if you want to keep it. Media files you edited or saved with the app are not affected by uninstalling.
• Retention: Media files remain entirely under your control; the history database is kept until you delete it or uninstall the app.

7. How We Protect Information

All processing happens locally, so there is no network-transmission exposure. We recommend you: keep your device secure with a screen lock; back up important files regularly; download and update the app only from the Microsoft Store. The app includes built-in integrity verification — if program files are tampered with, write operations are automatically locked to protect your files.

8. Your Rights

• Informed choice: decide whether to use the app after reading this policy;
• Permission control: grant or restrict file access at any time in system settings;
• Data management: view, back up, or delete the local history database at any time, and manage your media files through the file manager;
• Freedom to uninstall: remove the app and its local data at any time.

9. Children's Privacy

The app is not directed at children under 14 (or the applicable legal age in your jurisdiction) and does not collect children's personal information in any way. If you are a guardian and believe a child used this app without your consent, contact us via Section 11.

10. Changes to This Policy

• Material changes (for example, if a future version adds networking features) will be announced via Microsoft Store update notes or in-app notices;
• Minor textual updates will be made directly to this page; see the "last updated" date;
• We encourage you to review this policy periodically.

Appendix: Permission Summary (for Microsoft Store review)

1. File system access (user-selected files/folders), read/write: to open the user-designated images/videos, read their EXIF metadata and file attributes (file name, creation/modification times), and — only on explicit user action — write metadata changes, sync file timestamps, and batch rename. Access is limited to paths the user actively selects.
2. The app requests no other permissions (no location, camera, microphone, contacts, etc.), has no networking capability, and contains no advertising/analytics/tracking SDKs. The bundled open-source components and their licenses are listed in Section 4 and in the LICENSES/ folder.
