We use a minimal set of cookies. Analytics and marketing cookies load only after your explicit consent.

1. What a cookie is

A cookie is a small text file that a site stores in your browser to remember a preference or to measure how the site is used.

2. Which cookies we use

We group cookies into three categories:

  • Strictly necessary: for form security and protection against automated requests. No consent required.
  • Preferences: remember the language and the currency selected in the calculator.
  • Analytics: anonymously measure which pages are read. Loaded only after consent.

3. Managing consent

You can withdraw consent at any time from your browser settings or by deleting the cookies for this site.

Blocking strictly necessary cookies may break the enquiry form.

4. Third-party cookies

If an analytics service is enabled, it may set its own cookies under its own policy. We do not use advertising cookies for cross-site tracking without consent.

What we do not do

We set no advertising cookies and take part in no cross-site tracking networks.

We use no analytics cookies without consent. If we add analytics in future you will see a consent request before it loads, and you will be able to refuse without that limiting your use of the site.

We neither sell nor share data about your behaviour with third parties.

If you want to clear what the site has left on your device, do it from your browser settings under site data. You will lose only the chosen theme and the calculator's currency.

Which cookies are set

The full list. If something is not here, we do not set it.

The first two are not technically cookies but entries in your browser's local storage. They never leave your device and we do not read them.
