ChatBridge Privacy Policy

Last updated: October 29, 2026.

ChatBridge is a browser extension that saves your ChatGPT and Claude conversations into a searchable library inside your own browser. This policy explains what the extension handles and where it goes.

Summary

ChatBridge has no servers. The developer does not receive, collect, sell or share any of your data. Everything the extension saves stays in your browser on your device.

What ChatBridge reads

• Chats you sync. When you start a sync, ChatBridge opens a separate browser window on chatgpt.com or claude.ai and reads the chat list and the text of each conversation from the page, using the session you are already logged in with. It reads what you could see yourself on those pages. It does not read or store passwords, cookies or session tokens.
• Files you import. When you choose a ChatGPT or Claude data export file, ChatBridge reads it inside the browser. The file is not uploaded anywhere.

ChatBridge runs only on chatgpt.com and claude.ai. It does not run on other websites and does not read your browsing history.

What ChatBridge stores

Conversation titles, message text, timestamps, links back to each original chat, and the tags, projects, titles and summaries you create or that the extension generates. Tags and titles are generated on your device. No AI service is called.

This data is kept in your browser's IndexedDB storage. Your light or dark theme choice is kept in the extension's local storage. None of it is synced through your Google account.

What ChatBridge sends

Nothing. The extension contains no analytics, telemetry, crash reporting, advertising or remote code. Its content security policy blocks extension pages from connecting to any outside address, and every release is checked for code that could send data off the device.

Your control

• Export: Settings > Your data > Download backup creates a file you save yourself.
• Delete: Settings > Your data > Delete all data erases everything ChatBridge has stored.
• Uninstall: removing the extension deletes its stored data.

Permissions

• unlimitedStorage: lets a large chat library fit in local storage.
• Site access to chatgpt.com and claude.ai: needed to read your chats during a sync.

Children

ChatBridge is not directed at children under 13 and does not knowingly handle their data.

Changes

If this policy changes, the updated version will be posted at the same address with a new date.
