Claude Companion Privacy Policy

Last updated: 9 November 2026

Claude Companion is a Chrome extension that lets Claude Code, an AI coding tool running on your own computer, use your Chrome browser when you ask it to. This policy explains what the extension reads, where that goes and what it keeps.

The short version

• The extension talks only to programs on your own computer: the Claude Companion server and helper you install with it.
• We do not run any server. We do not collect, receive, sell or share your data.
• No ads, no analytics, no tracking.
• Passwords are never stored.

What the extension reads

Only when you, or Claude Code acting on your request, use one of its tools, the extension can read from the tabs it works in:

• Page content: text, links, form fields and page structure.
• Screenshots and screen recordings of a tab.
• Developer data of a tab: console messages, network requests and responses, cookies and site storage (used by the page check and debugging tools).
• The address and title of open tabs.

Where it goes

• Your own computer. What the extension reads goes over a local connection (127.0.0.1) to the Claude Companion server on your computer, and from there to your Claude Code session.
• Claude Code. Claude Code is made by Anthropic and is installed and signed in by you. What it sends to Anthropic is covered by Anthropic's own terms and privacy policy, not by this extension.
• GitHub, only when you click. If you use the bug board or task QA, an issue or comment is created on GitHub through your own GitHub CLI login, and only after you click to create it.

The extension itself sends nothing to the internet and has no remote server.

What it keeps

These stay on your computer, in Chrome's extension storage or in the Claude Companion folder:

• Your settings.
• Bugs you add to the bug board, with their screenshots.
• Recorded test steps (flows). A password typed while recording is not saved.
• Saved tab lists (addresses only) and recordings you choose to save.
• A random profile ID, used to tell your Chrome profiles apart. Your Google account is not read.

Removing the extension deletes its Chrome storage. Deleting the Claude Companion folder deletes the rest.

Permissions

The extension asks for broad permissions (all websites, debugger, native messaging) because Claude Code needs to work on any site you point it at, and to talk to the helper on your computer. They are used only for the tools described above.

Children

Claude Companion is a developer tool and is not meant for children.

Changes

If this policy changes, the new version is posted on this page with a new date.
