Last updated: June 20, 2025

Simple Summary

ChatChain does not collect, store, or transmit any of your personal data. Everything works locally in your browser.

1. Information We Collect

We collect NO personal information. The ChatChain extension:

  • Does not collect any personal data
  • Does not track your browsing activity
  • Does not store your ChatGPT conversations
  • Does not transmit any data to external servers

2. Local Storage

The extension stores only these settings locally on your device:

  • Enabled/Disabled state: Whether timestamps are currently active
  • Format preference: Your chosen timestamp format (time-only or date+time)

This data never leaves your browser and is only used to remember your preferences.

3. Permissions Used

The extension requests these permissions for functionality:

  • storage: To save your timestamp preferences locally
  • tabs: To open support website when user clicks footer link
  • Host permissions: To access ChatGPT website to add timestamps to user messages

4. Data Processing

All processing happens locally in your browser:

  • Timestamps are generated using your local system time
  • Text modification occurs only in your browser's memory
  • No data is sent to ChatChain or any third parties
  • No analytics or usage tracking is performed

5. Third-Party Services

The extension does not integrate with any third-party services or APIs. It works entirely offline within your browser.

6. Data Security

Since we don't collect any data, there's no risk of data breaches or unauthorized access to your information. Your ChatGPT conversations remain private between you and OpenAI.

7. Children's Privacy

Our extension does not collect any information from anyone, including children under 13.

8. Changes to This Policy

If we ever change this privacy policy, we will update the date at the top of this page. Since the extension doesn't collect data, any changes would likely be to clarify our practices, not to change them.

9. Open Source Transparency

ChatChain is developed with transparency in mind. The code is straightforward and can be inspected through Chrome's extension developer tools.

Bottom Line

Your privacy is completely protected. We don't want your data, we don't collect your data, and we don't need your data to provide this service.
