Cookies

Cookies right now

On an ordinary visit no cookie is set — not for analytics, not for advertising. The calculator itself needs none to work: it runs in your browser and stores nothing about you. There is one exception, described below rather than passed over in silence: the gr_int flag, which is written only if you deliberately open a page with ?internal=1 appended.

Google Analytics 4 is loaded on every page. It runs cookieless: no analytics cookie is set and no identifier is stored on or read from your device by Google’s tag. Loading the measurement tag does send data to Google LLC (United States) as a third party, including your IP address at the moment of connection. No advertising network is integrated, so no advertising cookie or identifier is set either.

Excluding our own visits

One exception, named here rather than passed over in silence: on every page view the measurement code checks whether the gr_int flag is present in your browser. That is our own exclusion for internal visits, so that our test traffic does not end up in the figures. It is written only when a page is opened with ?internal=1 appended — as a cookie with a lifetime of one year, and additionally in local storage. Without that, nothing is written, and nothing on this site links to it. It holds a single flag and nothing about you. You delete it by clearing this site’s data in your browser.

Consent

This site’s Consent Mode default denies advertising and analytics storage for every visitor, worldwide, and there is no consent banner here to change that default — it stays denied for everyone. That is why the measurement above runs cookieless rather than switching to a cookie-based mode, and why there is nothing for you to revoke. If a consent banner and cookies are introduced later, this page will list each one, its purpose and its lifetime, and you will be able to change your choice at any time.
