Claude Usage Tracker (Privacy Focused) von Apollox

Claude Usage Tracker is a lightweight, privacy-focused Firefox extension designed specifically for Claude Pro and Max users. It allows you to quickly check your remaining message limits without having to dig through your account settings.

How it works:
Anthropic does not provide a public API for usage limits, and counting messages locally is often inaccurate. To solve this, clicking "Fetch" in this extension briefly opens claude.ai/settings/usage in a hidden background tab, securely scrapes the exact percentages for your Session (5-hour) and Weekly limits, and instantly closes the tab.

Features:
Accurate: Grabs data straight from your official account settings.
Zero Interruption: The background tab uses an automatic kill-switch so it never interrupts your workflow or gets stuck open.
Privacy First: Your data never leaves your browser. There is no external tracking or analytics.

Note: This extension requires an active, paid Claude Pro or Max subscription to function, as free accounts do not have usage limits displayed on their settings page.
