Privacy Policy

What we collect

There's nothing to log in to — this site has no accounts and no forms. The numbers you type into a calculator (a cost, a price, a rate, a clock time) are processed entirely in your browser to produce a result. They are not sent to us, not stored on a server, and not shared with anyone. Close the tab and they're gone.

The infrastructure that serves this site, Cloudflare Pages, automatically logs standard technical information with each request — IP address, browser type, the page requested — the way any web host does, to deliver pages and guard against abuse. We don't use that to identify individual visitors, and we don't run any analytics package of our own.

Advertising

This site is not currently showing ads. ads.txt is live in anticipation of Google AdSense, but the ad script itself hasn't been added, and no ad-related cookies are being set today.

If that changes, Google and its advertising partners will be able to set cookies in your browser to serve and measure ads, and this page will be updated to describe that in full before it happens. In the meantime, Google's own opt-out controls already exist independent of any one site: manage or opt out of personalized advertising at Google's Ad Settings.
