ChronoTrace Privacy Policy

Last updated: October 9, 2025

1. Introduction

ChronoTrace (“the App”) respects your privacy and is committed to protecting your personal information. This Privacy Policy explains what data we collect, how we use it, and how we safeguard it while providing a quality experience.

2. Information We Collect

We collect limited information in the following scenarios:

• Photos and Albums: To access photos you choose to process and their metadata (for example, capture time). Photos are never uploaded or transmitted without your permission.
• Local Preferences: We store timestamp style settings (fonts, colors, formats) so the App can restore your selections on future use.
• Anonymous Device and Usage Analytics (optional): With your consent, we may gather anonymized data such as device model, iOS version, and feature usage frequency to improve the App.

3. How We Use Information

The collected data is used to:

• Provide and maintain the core functions of ChronoTrace;
• Optimize UI rendering, timestamp processing, and user workflows;
• Analyze performance and guide future enhancements;
• Comply with applicable laws and regulatory requirements.

4. Storage and Security

• Your photos and processed results are stored locally on your device by default and are not uploaded to any server.
• Personalized preferences are kept in `UserDefaults` solely for on-device configuration recall.
• Any anonymized analytics (if collected) are transmitted via HTTPS, follow data minimization principles, and contain no personally identifiable information.
• We employ reasonable technical and organizational safeguards to prevent unauthorized access, disclosure, or destruction.

5. Sharing and Disclosure

We do not share, sell, or rent your personal information to third parties without your explicit consent, unless required by law. If we introduce third-party SDKs or services in the future, we will notify you and obtain authorization in advance.

6. Permissions

The App may request the following system permissions:

• Photo Library: To read, edit, and save photos and related metadata.
• File Access (optional): To export processed images or back up settings when needed.

You can manage permissions anytime under iOS Settings > Privacy > Photos or relevant sections. Revoking a permission may restrict associated features.

7. Children’s Privacy

ChronoTrace is intended for users aged 13 or older. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such data, please contact us using the information below so we can promptly delete it.

8. International Users

If ChronoTrace servers operate in the People’s Republic of China (PRC), your data may be processed there. By using the App from other countries or regions, you acknowledge that privacy laws may differ and consent to the transfer and processing of your data under PRC law.

9. Policy Updates

We may update this Privacy Policy periodically. Significant changes will be communicated through in-app notices, release notes, or other reasonable means. The latest version will always be available on this page. Continued use of the App indicates acceptance of the updated policy.
