Privacy
Your sessions stay on your computer
Last updated 28 September 2026.
The app
Crawwwlers runs on your computer. The hooks it installs in your coding tool send each event (a session start, a tool call, a question) to the app through a local socket. Only your user account can open this socket. The app also reads your session transcripts on disk to get the model and the context use. None of this data leaves your computer.
The app has no analytics, no telemetry and no crash reports. It never sends your prompts, code, file paths or tool calls anywhere.
Update checks
When it starts, and once a day after that, the app downloads a small file from download.crawwwlers.com that names the newest version. The request sends nothing about you or your sessions. Like any web request, it shows your IP address to the server, which Cloudflare runs for us. If a newer version is out, the tray menu offers a link to download it.
Pro license checks
Apart from the update check, the app goes online only to check a Pro license key with Polar, who sell Pro for us. It checks when you activate a key, every few days while the key is active, and when you release a computer. Each check sends:
- The license key, and the ID that Polar gave to the activation on this computer.
- The name and operating system of this computer, so the customer portal can list your computers.
Polar replies with the status of the key and the name and email address of the buyer. The app shows these in Settings. The app keeps the key and the reply in its settings folder, in a file that only your user account can read. The free app never sends these requests.
Buying Pro
Polar is the merchant of record. Polar handles the checkout, your payment details, your email address and your receipts under Polar's privacy policy. We see what Polar shows a seller: your name, email address, what you bought and when.
This website
GitHub Pages hosts crawwwlers.com. GitHub can log your IP address when you visit, as GitHub's privacy statement describes. If you press the theme button, your browser's local storage keeps your choice. The site never sends it anywhere. The page loads Polar's checkout script from the jsDelivr CDN, so the purchase can open over the page.
The site uses PostHog analytics to count visitors and see what they look for. PostHog is hosted in the EU and runs 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, your device type, your approximate location and the page that sent you here. PostHog uses your IP address to tell visits apart, but does not store it, as PostHog's privacy policy describes. If you block PostHog with a content blocker, the site still works.
Changes
If the data that the app or the site collects changes, we update this page and the date at the top.
