Cookie Policy

We use as few cookies as possible — and none for advertising.

Essential cookies

A small number of cookies may be needed for the site to work correctly, such as remembering your preferences within a session.

We may use privacy-friendly, aggregated analytics to see which pages and calculators people find useful. These do not identify you.

We do not use advertising or cross-site tracking cookies, and we do not sell data to third parties.

You can block or delete cookies in your browser settings. Blocking all cookies may affect how parts of the site behave.
