Privacy Policy

Your data stays on your device

This extension does not collect, transmit, or share any personal information. Everything it reads stays local.

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

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

scripting Allows injecting a parser script into an already-open Claude usage page as a fallback when the API is unavailable.
storage Saves usage data locally between browser sessions so your toolbar badge persists after restarting Chrome.
alarms Schedules an automatic data refresh to keep the badge current based on your chosen interval.
claude.ai Host permission required to query the Claude.ai usage API and read usage data from the settings page.

No tracking, no accounts

The extension has no user accounts, no sign-up, and no registration. It does not track usage patterns, browsing history, or any personally identifiable information. It does not use cookies of its own.

Changes to this policy

If this policy changes, the updated version will be posted at this URL. The extension version number in manifest.json will also be incremented.
