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.
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.
The extension makes authenticated requests every 2 minutes to:
https://claude.ai/api/organizations — to identify your organizationhttps://claude.ai/api/organizations/[your-org-id]/usage — to read your session and weekly usageThese 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.
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.
All local data is stored via the Chrome extension storage API on your device only:
None of this leaves your device.
The extension requests the following Chrome permissions:
storage — to save your settings and future library data locally on your deviceclipboardWrite — to copy Markdown content to your clipboard when you click the Copy buttoncontextMenus — to add the right-click "Ask Claude about this" menunotifications — to show a one-time welcome message on installscripting and activeTab — to read the active tab's content for the extension popup statshost_permissions: https://claude.ai/* — the extension only runs on claude.ai, nowhere elseClaudeMate 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.
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.
