Calculator inputs

Every calculator on this site runs entirely in your browser. The numbers you enter are never sent to us, stored, or shared — there is no server receiving them, and there are no user accounts.

Hosting logs

This site is served by a static hosting provider (Cloudflare Pages). Like any web host, it may process standard technical information — such as IP address, browser type, and pages requested — to deliver the site and protect it from abuse. We do not use that information to identify or profile visitors.

Cookies and advertising

This site itself sets no tracking cookies. If third-party advertising (such as Google AdSense) is added in the future, those providers may use cookies to serve and measure ads, including personalised ads where consent rules require it. This policy will be updated, and any required consent notice added, before advertising is switched on.
