GPT Master Web Extension – Privacy Policy

Effective Date: September 22, 2025

This policy explains how GPT Master Web Extension handles your information when you use the Chrome extension and related services.

Single Purpose

Extension Purpose: GPT Master Web Extension has a single, focused purpose: to enhance the ChatGPT user experience with productivity tools including smart follow-up suggestions, conversation organization (folders, starring/pinning), message timestamps, and conversation management features. The extension does not perform any other functions beyond enhancing ChatGPT productivity and organization.

1. What We Collect

• Local Extension Data: Folder names, conversation mappings, and settings stored locally in your browser (chrome.storage.local or localStorage). This data never leaves your device.
• Anonymous Usage Data: GA4 collects anonymized usage stats (extension version, browser type, events, errors) with no personal data or conversation content.
• Web Browsing Activity: We do not collect, access, or monitor your web browsing activity, browsing history, or any content you view on websites. The extension only operates within the ChatGPT interface and does not track your general web browsing.
• ChatGPT Content: We do not access, read, or collect the content of your ChatGPT conversations. The extension only manages organizational features (folders, labels) without accessing conversation content.

2. How We Use Data

• Provide and improve features
• Monitor performance and fix issues
• Analyze trends in aggregate

We do not sell your data, use it for targeted ads, or access your ChatGPT content.

2.1. Limited Use Policy

We limit our use of your data to the practices disclosed in this policy. We do not use your data for any purpose other than providing and improving the GPT Master Web Extension service.

3. Data Sharing

• Google Analytics 4: We share anonymous usage statistics (extension version, browser type, feature usage events, error reports) with Google Analytics 4. This data is anonymized and does not include personal information, conversation content, or browsing history. Google Analytics 4 is subject to Google's privacy policy.
• No Other Third Parties: We do not share your data with any other third parties, advertisers, or marketing companies.

4. Data Storage & Security

• Local Storage: All extension data (folders, settings, tokens) is stored locally on your device using Chrome's secure storage APIs. This data never leaves your device and is not transmitted to our servers.
• No Account Data: We do not collect account data as no login is required to use the extension.
• Encryption: Local data is stored using Chrome's built-in security mechanisms. We rely on Chrome's storage APIs to protect your information.

5. Data Retention

Data stored locally in the extension remains on your device until you uninstall GPT Master or manually clear Chrome storage. Since we do not store data on external servers, uninstalling the extension removes all stored data. Users can also clear stored data through Chrome's extension site settings.

6. Your Rights & Choices

• Access & Control: You can manage or delete your data at any time through Chrome's extension storage tools.
• GA4 Opt-Out: Disable analytics by removing GA4 credentials from the extension’s configuration file.
• Uninstall: Removing the extension deletes all stored data from your browser.

7. Children's Privacy

GPT Master Web Extension is not intended for children under the age of 13. We do not knowingly collect personal information from children.

8. Changes to This Privacy Policy
