Your companion for Claude.ai

Privacy Policy

Last updated: April 21, 2026

ClaudeMate is a browser extension for Claude.ai that adds a context counter, session/weekly usage bars, Copy as Markdown buttons, and right-click integration. This policy explains what data the extension handles.

The short version: ClaudeMate does not collect, transmit, sell, or share any of your personal data. Everything the extension does happens inside your own browser. No external servers are involved.

What data ClaudeMate accesses

1. Claude.ai page content (on-page only)

When you visit claude.ai, the extension reads the visible conversation content in order to count tokens, render the Copy as Markdown button, and calculate word and reading statistics. This reading happens locally in your browser and is never transmitted anywhere.

2. Your Claude usage statistics (fetched from Claude's own API)

The extension makes authenticated requests every 2 minutes to:

These requests use your existing Claude.ai browser session — the same way the official claude.ai/settings/usage page fetches data. The results are displayed in the badge and popup; they are not sent anywhere else.

3. Selected text (for right-click "Ask Claude about this")

When you highlight text on any webpage and use the right-click menu, the selected text is placed into a new claude.ai tab's composer. The text is stored briefly in your browser's local storage to pass it between tabs, and is automatically deleted immediately after being inserted.

What data ClaudeMate stores locally

All local data is stored via the Chrome extension storage API on your device only:

None of this leaves your device.

What ClaudeMate does NOT do

Permissions explained

The extension requests the following Chrome permissions:

Third-party services

ClaudeMate does not use any third-party analytics, tracking, or advertising services.

The only external service the extension communicates with is Claude.ai itself (claude.ai/api/*), using your already-authenticated session.

Changes to this policy

If the extension's data handling ever changes (for example, if a future feature adds cloud sync), this policy will be updated and users will be notified via the extension's changelog before the change takes effect.
