Claude Usage Tracker runs entirely in your browser. It reads the usage percentages and reset times that claude.ai already shows you, and stores them only on your device. If you turn on the optional auto-refresh (off by default), it asks claude.ai for the same figures using your own logged-in session; requests go only to claude.ai, never to us or any third party. It never reads your conversations and collects no personal data. The optional Pro license key is saved only on your device. Payments are handled by Stripe on threadturbo.com.
