Privacy

Updated 11 October 2026. KatmanKit is a free calculator. You do not need an account.

Your print jobs stay in your browser

We do not upload calculator values, job names, customer references, saved JSON files or quotes. The downloadable HTML file makes no tracking requests.

Optional usage counts

Counting is off until you choose “Allow usage counts”. We then set a random first-party browser ID in a secure cookie for up to 30 days. We store that ID, creation and expiry times, whether it is a marked test, and simple flags for calculator use, seeing the optional purchase price, downloading and your optional answer. We do not store IP addresses, browser fingerprints, full browsing history or contact details in this database. These are browser counts, not verified people.

Your allow/decline preference is stored on this device. Choose “No thanks / remove my counts” on the calculator to delete the current counting record and cookie. If counting is unavailable, retry deletion later. Clearing cookies removes the link to your previous record. Expired records stop contributing to totals and are deleted when the next new counting session is created.

Hosting

Cloudflare serves the site and processes network information such as your IP address to deliver and protect it, even when you decline our usage counts. See Cloudflare’s privacy policy. KatmanKit’s own counter does not save your IP. Aggregate counts may be published; individual records are not exposed by the public API. Payment is not available and we collect no payment information.

No third-party advertising, analytics scripts, fonts or customer login are used. If you block storage or decline counts, the calculator and download still work.
