This is a static site. The calculators run entirely in your browser; nothing you type is sent to us. We set no cookies ourselves and have no accounts or forms.

Our host may keep standard server logs (IP address, pages requested) for security. If we add advertising (e.g. Google AdSense) or affiliate links later, those partners may use cookies to serve and measure ads; this page will be updated before that happens and, where required, a consent banner shown.
