Cookies & advertising choices

Updated October 21, 2026

Calculator operation

The calculators do not require advertising cookies or a user account. Current calculator inputs are held in browser memory while you use a page. Hosting and security services may use their own necessary technologies to deliver and protect the site.

Advertising and consent

Google advertising is optional and disabled by default in this application. If the operator enables it, Google or its partners may use cookies or similar storage for advertising, measurement and fraud prevention. Where a consent message is shown, use its choices before agreeing and its privacy-options control to change or withdraw your choice. A privacy notice or this page is not itself a consent-management platform.

If advertising appears and you cannot find or reopen its privacy-options control, contact cindercalc@gmail.com with the page address and your region. The calculators remain usable without advertising consent. Withdrawing consent stops new application-controlled ad units; the consent provider and Google must also apply the relevant vendor signals. Clearing browser storage can remove locally stored identifiers, but does not erase information already processed by a provider.
