Cookies

What is stored

On an ordinary visit no cookie is set on this site — not for measurement, not for advertising. The calculators need none to work: they run in your browser and the figures you enter never leave it. 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.

The measurement tag, and why it stores nothing

The site loads Google Analytics 4 to count visits. Consent Mode is set to deny analytics and advertising storage before that tag runs, and the default is the same for every visitor in every country — there is no consent banner here, of ours or Google’s, that could change it. GA4 therefore runs cookieless: it sends aggregated pings, sets no analytics cookie, and stores no identifier on your device.

No advertising network is wired in, so there is no advertising cookie to describe. If that ever changes, this page will list each cookie, its purpose and its lifetime, and give you a way to change your choice, before any of them is set.

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.

Cookies set by others

One third-party script runs on this site: the Google measurement tag described above, which sets no cookie here because storage consent is denied before it runs. Beyond it there are no fonts loaded from another domain, no video players and no social widgets. Links to other sites are ordinary links; what those sites do is described in their own policies.
