What the extension does
Claude Usage Monitor reads your Claude.ai usage statistics — session percentage, weekly percentage, and reset times — and displays them in your browser toolbar. It fetches this data directly from Claude's internal API using your existing login session.
No data ever leaves your device to any server other than claude.ai itself — the same server your browser already talks to when you use Claude.
Data collected and stored
- Session usage percentage and reset time
- Weekly usage percentage and reset time
- Timestamp of the last successful refresh
- Your Claude organization ID (cached to avoid repeated API calls)
All of this is stored exclusively in chrome.storage.local — on your device, in Chrome's local storage. It is never synced to Google's servers, never sent to us, and never shared with any third party.
Network requests
The extension makes requests exclusively to https://claude.ai/api/… — the same origin as the Claude.ai web app. These requests use your existing browser session cookies and are authenticated as you.
No requests are made to any other domain. There are no analytics, no telemetry, no crash reporting services, and no ad networks.
Permissions explained
