No page of the site sets a cookie, advertising or otherwise. The calculators run in your browser and keep nothing once the tab is closed.

Anonymous stability monitoring

To find broken pages, script errors, slow loading and buttons that do not respond, the site loads Microsoft Clarity, from Microsoft Ireland Operations Limited, in its cookie-free mode. Clarity then sets no cookie (no _clck, _clsk, MUID or CLID), gives every page view a one-off identifier and does not link visits. The price, state and buyer details you enter, and page content, are masked before anything is sent. As nothing is stored on your device, there is no cookie banner. Blocking the clarity.ms domain stops this monitoring without affecting the calculators.

The privacy policy explains who receives the monitoring data and for how long.
