Privacy Policy — Claude Usage Tracker

Last updated: June 2026

Claude Usage Tracker does not collect, transmit, or share any personal data with any third party, with the exception of optional license key verification handled by Gumroad, and anonymous in-extension click/usage analytics handled by Google Analytics (see below). All core data processing occurs locally on the user's device.

Data Handling

Data	Where it stays	Sent externally?
Usage metrics (session %, weekly %, reset times)	Device only (`chrome.storage.local`)	No
User settings (thresholds, language, notification preferences)	Chrome sync storage (`chrome.storage.sync`)	Synced across the user's browsers via their Google account; not transmitted to any external servers by the extension
Claude.ai session cookies	Not accessed, read, or stored by the extension	No — handled automatically by the browser
Supporter license key	Device only (`chrome.storage.local`)	Sent to Gumroad API for one-time verification only
Supporter tier	Device only (`chrome.storage.local`)	No
Anonymous usage analytics (e.g. button clicks, settings changes, panel opens)	Anonymous random ID stored locally (`chrome.storage.local`)	Sent to Google Analytics 4 — no personally identifiable information included

What the Extension Does

Fetches usage data from claude.ai using your existing browser login session.
Displays usage metrics locally in the browser toolbar badge and popup.
Sends optional browser notifications (toast or system notifications) based on user preferences.
All processing happens on the user's device. The extension does not operate any backend server.

Optional: Supporter License Verification

If you choose to activate a Supporter license key, the extension sends that key to the Gumroad license verification API (api.gumroad.com/v2/licenses/verify) for a one-time validation. No other personal data is included in this request.

Optional: Anonymous Usage Analytics

The extension records a small set of anonymous interaction events (such as clicking refresh, opening a panel, or changing a setting) to understand which features are used, via Google Analytics 4 (Measurement Protocol). Each event is tied only to a randomly generated identifier stored on your device — never your name, email, Claude.ai account, or any content you work on. No personally identifiable information is ever included.

Google's privacy policy governs this interaction: https://policies.google.com/privacy

What the Extension Does Not Do

Does not access, read, store, or transmit authentication credentials or cookies.
Does not track browsing history or website content.
Does not collect personally identifiable information through analytics.
Does not execute remotely hosted code.
