Usage Tracker for Claude

Last updated: 2026-06-18

Not affiliated with or endorsed by Anthropic.

This extension helps you see your Claude.ai usage limits at a glance. We designed it to collect as little as possible. This page explains exactly what is collected, what is never collected, and where the data goes. Plain and complete, with no surprises.

WE COLLECT What we collect

Anonymous usage events. When you use the extension (open the popup, view your numbers, interact with the Pro section, etc.), we record structured analytics events describing which action happened, not your account data. Usage percentages are reported only as coarse buckets (for example 75-90), never as exact figures tied to your account.
A random install identifier. On first run the extension generates a random UUID called install_id and stores it locally. This is the only identifier attached to events, and it cannot be traced back to you. It exists so we can count installs and understand the usage funnel anonymously.
Basic technical context. Each event carries the event name, a UTC timestamp, and the extension version.
An optional waitlist email. If (and only if) you choose to type your email into the optional "Pro is coming soon" early-access field and submit it, we store that email so we can contact you about a future Pro version. This is entirely optional. The extension is fully functional without it.

NEVER What we never collect

No Claude conversation content. We never read, store, or transmit your prompts, messages, chats, or any text from your conversations.
No account identifiers. We do not collect your name, your Claude account, your email address (beyond the optional waitlist field above), your login, or any session tokens.
No personal data. We do not build a profile of you, do not track you across other sites, and do not sell or share data with advertisers.
No exact usage figures. Your precise usage percentages stay on your device; only bucketed ranges are ever sent.

How usage data is read

Usage numbers are read directly from the Claude.ai page you already have open, in your browser, and shown back to you. The extension requests access only to https://claude.ai/*. It uses the storage permission to keep your settings and the anonymous install ID on your device, the notifications permission for optional usage alerts, and the alarms permission to refresh your numbers periodically while a Claude.ai tab is open.

Analytics provider

Anonymous events are sent to PostHog (posthog.com), a product-analytics service, where they are associated only with your random install_id. If you submit the optional waitlist email, it is stored in PostHog as a person property on your anonymous profile, kept separate from the raw event stream. The email is used solely to let you know if a Pro version launches.

Data retention and your choices

You can uninstall the extension at any time to stop all future event collection. When you do, a single anonymous uninstall event may be recorded. To request deletion of the anonymous data associated with your install_id, or removal of a waitlist email you submitted, contact us at the address below and we will remove it.

Questions about this policy, or requests to delete data associated with your install_id or a submitted waitlist email, can be sent to demidchick.pavel@gmail.com.

Changes to this policy

If this policy changes, we will update the "Last updated" date above and reflect the change in the extension's store listing.
