ChatGPT Brancher ("we", "our", or "the extension") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our Chrome extension.
Information We Collect
Analytics Data (Anonymous)
We use Mixpanel to collect anonymous usage analytics to improve the extension. The data we collect includes:
•
Anonymous User ID: A randomly generated UUID that is not linked to your identity
•
Event Types: Actions you perform (e.g., "Branch Created", "Settings Changed")
•
Extension Version: The version number of the extension you're using
•
Language Preference: Your selected language (English or Korean)
•
Settings: Your chosen close action (Nothing/Archive/Delete)
•
Geographic Data: Country, Region, and City (derived from IP address for geolocation purposes only; IP addresses are not stored)
What We Do NOT Collect
We explicitly do NOT collect:
•
❌ Conversation Content: We never access or store your ChatGPT conversations
•
❌ Message IDs: We do not collect specific message identifiers
•
❌ Conversation IDs: We do not track which conversations you branch
•
❌ Authentication Tokens: We do not store or transmit your ChatGPT login credentials
•
❌ Personal Information: We do not collect names, email addresses, or any personally identifiable information
•
❌ Browsing History: We do not track URLs or your browsing activity
How We Use Information
The anonymous analytics data is used solely to:
•
Understand how users interact with the extension
•
Identify and fix bugs
•
Improve features based on usage patterns
•
Track the number of active users
Data Storage
•
Local Storage: Your settings (language preference and close action) are stored locally in your browser using Chrome's storage API
•
Session Storage: Authentication tokens are temporarily stored in your browser session only and automatically cleared when the session ends to facilitate branch operations and are never transmitted to external servers
•
Analytics Storage: The anonymous user ID is stored in your browser's localStorage by Mixpanel
All data remains on your device except for the anonymous analytics data sent to Mixpanel.
Mixpanel is configured with privacy-focused settings:
•
IP addresses are used for geolocation but not stored
•
URLs and referrers are not tracked
•
No personal identifiers are collected
How the Extension Works
ChatGPT Brancher:
1.
Accesses ChatGPT Requests: The extension accesses ChatGPT’s in-browser API requests only within your browser context to identify authentication tokens required for creating branches. All operations remain entirely local—no data is transmitted externally.
2.
Local Processing (No Background Server Involved): All processing happens entirely within your local browser environment. No background server or external API operated by us receives any data.
3.
No External Transmission: Authentication tokens and conversation data are never sent to our servers or any third party
4.
Uses ChatGPT's API: Branch operations use ChatGPT's official branching functionality
Your Rights
You have the right to:
•
Opt Out: You may opt out of analytics by using a browser-level blocker (e.g., uBlock, Brave Shield) or by disabling Mixpanel tracking within your network settings.
•
Delete Data: Uninstalling the extension removes all local data
•
Access Data: The anonymous data collected cannot be tied back to you individually
Data Retention
•
Local Data: Stored until you uninstall the extension or clear browser data
•
Analytics Data: Retained by Mixpanel according to their data retention policy
