Privacy Policy

Timestamp Camera (the "App") is provided by Yong Wang ("we", "our", or "us"). We are committed to protecting your privacy. This Privacy Policy explains how we handle information when you use the App.

Please read this privacy policy carefully. If you do not agree with the terms of this privacy policy, please do not access the application.

1. Information We Collect

1.1 Information You Provide

We do not require you to create an account or provide personal information to use the basic features of Timestamp Camera. The app is designed to function on your device.

1.2 Diagnostics & Analytics (Limited)

• Apple Diagnostics/Analytics: Depending on your device settings, Apple may provide aggregated and/or anonymized diagnostics information (such as crash reports and performance data) to developers. We may use this information to improve app stability and performance.
• No Third-Party Analytics SDKs: Currently, we do not use third-party analytics SDKs to track your activity across apps or websites.
• Future Analytics (Optional): If we introduce our own analytics in the future to improve performance and stability, we may collect limited, non-personal usage events (e.g., feature usage, device and app version). We will update this Privacy Policy and our App Store privacy disclosures before enabling such analytics.

1.3 Information Accessed with Your Permission

• Photo Library: Required to import images for background removal, batch processing, and other editing features, and to save processed results. We do not upload your photos to any server.

2. How We Use Your Information

We use the information we handle to:

• Provide, maintain, and improve our application
• Process your photos and videos on your device
• Respond to your inquiries and provide customer support
• Improve stability and performance using limited diagnostics information (if available)

3. Data Storage and Security

3.1 Local Processing

All image processing, including background removal, object erasure, AI uncropping, and image enhancement, is performed locally on your device using on-device AI models. Your photos never leave your device unless you choose to share them.

3.2 No Cloud Storage

We do not store your photos on our cloud servers. Your media remains on your device and under your control. AI models used for processing are stored locally on your device after initial download.

3.3 Subscription Data

If you subscribe to premium features, purchases are managed by Apple through the App Store. We do not collect or store your payment information.

4. Third-Party Services

4.1 Apple Services

• App Store / StoreKit: Handles in-app purchases, subscriptions, and purchase verification

4.2 On-Device AI Processing

The App uses Apple's Vision framework and Core ML models (such as image segmentation, inpainting, and enhancement models) to process your images. All AI processing is performed entirely on your device. No images or processing data are sent to external servers.

5. Data Sharing and Disclosure

We do not sell, trade, or rent your personal information to third parties.

We may disclose information only if required to:

• Comply with legal obligations
• Protect and defend our rights or property
• Prevent or investigate possible wrongdoing
• Protect the personal safety of users or the public

6. Children's Privacy

Our application is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided personal information, please contact us.

7. Your Rights and Choices

7.1 Access and Control

• You can revoke photo library permissions at any time through your device settings
• You can delete the app and local data at any time by removing the app from your device
• If you contact us for support, you can request deletion of those support communications

7.2 AI Model Data

AI models downloaded for on-device processing are stored locally. You can remove them by deleting the app from your device.

8. International Data Transfers

Image processing occurs on your device, so your photos are not transferred to our servers. If Apple diagnostics/analytics are enabled on your device, Apple may process related information in locations where it operates its services.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will post the updated Privacy Policy and update the "Last Updated" date. If changes are material, we will provide additional notice where appropriate.

10. California Privacy Rights (CCPA)

If you are a California resident, you have specific rights regarding your personal information under the CCPA. Because we do not sell your personal information and do not upload your media to our servers, many of these provisions have limited applicability to the app.

11. GDPR Compliance (For EU Users)

For users in the European Union:

• We aim to minimize data handling and use it only for legitimate purposes
• Media processing occurs on your device
• You can control permissions and delete local data by removing the app
• You may contact us with privacy questions or requests related to support communications
