Privacy Policy

Last Updated: April 14, 2026 App: Marmot ID Photo (土拨鼠证件照)
Core Commitment: Your photos and facial data never leave your device. All processing happens locally (On-Device).

1. Zero Data Collection & Local Processing

Marmot ID Photo is designed with privacy at its core. We are committed to protecting your personal information. Our primary policy is simple: we do not collect, store, or share your photos or personal data.

2. Facial Data & Recognition

To provide ID photo features, the app uses on-device facial detection technology.

3. Permissions

The app requests the following permissions only when necessary:

You can manage or revoke these permissions any time in iOS Settings → Privacy & Security → Marmot ID Photo.

4. Third-Party AI Services

We DO NOT use any third-party cloud AI services. All AI-driven features (person segmentation, facial landmarks, matting) are powered by Apple's on-device technologies (Vision and CoreML), ensuring your data remains private and local.

5. Advertising (Google AdMob)

The app displays a single rewarded-interstitial advertisement when you save a photo. This helps fund development. Ads are served by Google AdMob, which may collect limited data:

For users in the EEA, UK, and Switzerland, Google's Consent Management Platform (UMP) presents a choice screen on first launch. You can change your consent any time via App menu → Privacy Choices.

6. Data Retention Policy

Since no photo or facial data is ever uploaded to our servers, we retain none of it. Preference data such as language selection, appearance, and export quality is stored locally on your device and is deleted when the app is uninstalled.

7. Children's Privacy

Our app does not collect any personal data and is safe for users of all ages. We do not knowingly collect any information from children under the age of 13 (or 16 in certain jurisdictions). If you believe a child has provided personal information to us, please contact us immediately.

8. Your Rights (GDPR / CCPA / LGPD)

Because we collect no personal data, the rights of access, rectification, deletion, and portability are automatically satisfied. If you wish to verify this, email us using the contact below — we will respond within 30 days.

9. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in the app or regulatory requirements. Updates will be reflected by the "Last Updated" date at the top of this page.
