Privacy notes

Updated 24 October 2026. This is a plain description of how the site behaves, not a law-firm policy.

Calculator inputs

Numbers and project names are used in your browser to compute a result. The calculation is not sent to a server, and the site does not keep an account or a saved project. Closing or reloading the page clears what you typed. Copying a result uses your device's clipboard only if you press "Copy this result".

Cookies and analytics

The calculator itself does not set a tracking cookie.

Google Analytics is not included unless a measurement ID is set when the site is built. If that ID is present and matches Google's measurement-ID shape, the Google tag is included in the page and Google may set cookies under its own terms.

Google Search Console verification, if added at build time, is a meta tag used to prove ownership of the domain. It does not track visitors by itself.

Advertising and affiliate partnerships

This website is currently free to use and does not display advertisements. In the future, we may earn revenue through clearly identified advertising and affiliate partnerships. Our calculators will remain free to use.

No advertising script, affiliate tracking script, or advertising cookie is installed today. The ads.txt file at the site root contains no publisher record yet.

Display advertising, if added, is expected to be Google AdSense. Affiliate links, if added, will be identified as paid partnerships. Before either goes live, this page will be updated with the providers, the cookies they may set, and the consent controls required to run them.

Hosting logs

The host that serves the site may keep ordinary connection logs, such as IP address, browser type, and the page requested. That is a function of hosting, not of the calculator.

Children

The site is written for adults making household cost decisions. It does not ask for anyone's age and it is not directed at children.
