Cookie Policy

The calculators themselves run entirely in your browser and don't require cookies to function — there is no login and no saved preferences. The only thing this site stores itself is your cookie consent choice (accept or decline), kept in your browser's local storage rather than a cookie, so we don't have to ask you again on every visit.

If you accept the cookie banner shown on your first visit, Google Analytics sets the following cookies to distinguish you as a returning visitor for aggregated usage statistics:

• _ga — distinguishes unique visitors. Expires after roughly 2 years.
• _ga_<container-id> — used by Google Analytics 4 to persist session state. Expires after roughly 2 years.

None of these cookies are set until you click "Accept" — declining, or simply not choosing, means no analytics cookie is ever placed. See our Privacy Policy for what this data is used for.

This site does not currently use any advertising cookies. If that changes, this page will be updated first to describe exactly what is set, why, and how you can control it.

Beyond the consent choice above, your browser also lets you view, block, or delete cookies from any site at any time through its own settings, if you'd like to manage this directly.
