Privacy

Your sessions stay on your computer

Last updated 26 September 2026.

The app

Claude Crawlers runs on your computer. The hooks it installs into Claude Code send each event — a session starting, a tool call, a question — to the app over a local socket that only your user account can open. The app also reads your session transcripts on disk to learn the model and how full the context is. None of that leaves your computer.

The app has no analytics, no telemetry and no crash reporting. It never sends your prompts, code, file paths or tool calls anywhere.

Pro licence checks

The only time the app goes online is to check a Pro licence key with Polar, who sell Pro for us: when you activate a key, every few days while it is active, and when you free a computer. Each check sends:

• the licence key, and the id Polar gave this computer's activation;
• this computer's name and operating system, so the customer portal can list your computers.

Polar answers with the key's status and the name and email address it was bought under, which the app shows in Settings. The key and that answer are kept in a file only your user account can read, in the app's own settings folder. The free app never makes these requests.

Buying Pro

Polar is the merchant of record: the checkout, your payment details, your email address and your receipts are handled by Polar under Polar's privacy policy. We see what Polar shows a seller: your name, email address, what you bought and when.

This website

claudecrawlers.com is hosted on GitHub Pages. GitHub may log your IP address when you visit, as GitHub's privacy statement describes. If you press the theme button, your choice is saved in your browser's local storage and never sent anywhere. Polar's checkout script is loaded from the jsDelivr CDN so the purchase can open over the page.

To see how many people visit and what they come for, the site uses PostHog analytics, hosted in the EU, in cookieless mode: it sets no cookies and stores nothing in your browser. It records the pages you view, the links and buttons you click (including which download and which Pro button), your browser, device type and rough location, and the page that sent you here. Your IP address is used to tell one visit from another and is not stored, as PostHog's privacy policy describes. Blocking PostHog with a content blocker does not stop the site working.

Changes

If what the app or the site collects changes, this page changes with it, and the date at the top says when.
