Token Counter privacy policy

Last updated: October 8, 2026

Token Counter is a browser extension that shows your Claude usage limits. This policy describes exactly what it does with data — which is very little.

What the extension collects

Nothing. The extension does not collect, store on any server, sell or share any personal data, browsing history, conversation content or usage statistics. It has no accounts, no tracking and no third-party analytics inside the extension.

What stays in your browser

The extension keeps a small amount of data in your browser's local extension storage (chrome.storage.local): your settings (plan, whether the bar is shown, which number the toolbar icon shows), the latest usage percentages and reset times read from claude.ai, a short local log used only as a fallback estimate, and the state of the rating prompt — up to five dates on which you used the extension and whether you have answered or dismissed the prompt. This data never leaves your device and is deleted automatically when you remove the extension.

Network requests

The extension talks to exactly one site: claude.ai. It reads the same usage endpoint that Claude's own settings page uses, authenticated by your existing claude.ai session — through an open claude.ai tab when there is one, otherwise from its background service worker — to show your official session and weekly limit percentages on the toolbar icon, in its tooltip, in the popup and in the bar under the chat. It checks about once a minute while your usage is changing and about every five minutes otherwise, and also when you open the popup or a Claude reply finishes. The latest percentages and reset times are kept only in your browser's local extension storage. No request is ever sent to any other server, and nothing about you is transmitted to the extension's developer.
