Cookies
How we would use analytics and advertising cookies, if introduced: consent starts denied by default for every visitor, in every country — not just the EEA, the UK and Switzerland — and no cookie would be set without your action. Right now the site sets no analytics or advertising cookie at all.
Cookies this site sets
On an ordinary visit, none. The calculators run entirely in the browser and keep nothing; we use no session cookies and no preference cookies.
Google Analytics loads on every page, but the Consent Mode v2 block ahead of it denies storage to every visitor, in every country, and there is no notice on this site that could grant it. The tag therefore runs without writing a cookie and without keeping an identifier.
One exception, named here rather than passed over in silence: the gr_int flag, our own exclusion for internal visits, so that our test traffic does not end up in the figures. It is written only when you deliberately open a page with ?internal=1 appended — as a cookie with a lifetime of one year, and additionally in local storage — and the measurement code reads it on every page view. On an ordinary visit nothing is written, and nothing on this site links to it. It holds a single flag and nothing about you, and you delete it by clearing this site’s data in your browser.
Requests that leave this domain
The only one is the Google Analytics tag (G-EPBKX0SKVV), loaded from googletagmanager.com. Fonts and images are served from this domain.
There is no Google AdSense and no other ad network: no third party sets a profiling cookie here.
Staying in control
There is no consent to withdraw, because storage is denied by default already. If you would rather block the request to the tag entirely, you can do so from your browser or from Google’s settings:
Blocking measurement does not affect your use of the site in any way. The legal basis is legitimate interest: measurement neither writes nor reads information on your device, so it needs no consent under Article 5(3) of the ePrivacy Directive.
