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

• HealthKit: Optional. Used to write mindfulness session data and sleep analysis to Apple Health. We only write data — we do not read your other health data. HealthKit data is never shared with third parties or used for advertising.
• Notifications: Optional. Used to send local reminders for daily meditation, streak warnings, and trial expiry. All notifications are local — no data is sent to external servers.

2. How We Use Your Information

We use the information we handle to:

• Provide meditation timer, breathing exercises, sleep sounds, and journaling features
• Store your meditation sessions, mood entries, and journal locally on your device
• Write mindfulness and sleep data to Apple Health (with your permission)
• Send local notification reminders (with your permission)
• Process subscription purchases through Apple's StoreKit

3. Data Storage and Security

3.1 Local Processing

All meditation sessions, breathing exercises, sleep records, mood entries, and journal content are processed and stored locally on your device using Apple's SwiftData framework.

3.2 No Cloud Storage

We do not store your photos or videos on our cloud servers. Your media remains on your device and under your control.

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
• HealthKit: Writes mindfulness session and sleep analysis data to Apple Health (with your explicit permission)

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 HealthKit or notification permissions at any time through your device settings
• You can delete the app and all 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 HealthKit

HealthKit integration is optional. The app functions fully without HealthKit access. You can revoke HealthKit permissions in Settings → Health → Data Access.

8. International Data Transfers

All data processing occurs on your device. We do not transfer your meditation data, mood entries, or journal content to any server. 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
