Privacy policy

The calculators run in your browser. We do not require an account, and the measurements you enter are not sent to us by the calculator code.

Vercel Web Analytics

We use Vercel Web Analytics to understand aggregate page views and site performance. It is enabled at the site level and is intended to provide privacy-conscious, aggregated usage information without adding Google Analytics or custom tracking code. Vercel’s own policies govern any processing by that service.

Google AdSense

The site includes Google’s AdSense script for publisher verification and, if advertising is approved and configured, ad delivery. No manual ad placements are promised on this page, and the presence of the script does not mean Google has approved the site or that ads are currently serving. Google may process device, usage, or cookie information according to its policies.

Consent and cookies

Where applicable, Google’s consent controls determine whether personalized advertising or related storage may be used. You can also use browser controls to clear or block cookies. The choices and disclosures shown by Google may vary by region.

Server logs

Our hosting provider may retain routine technical logs, such as IP address, browser information, requested page, and timestamp, for security and reliability.
