Privacy policy

What data we process

This site has no account, no sign-up and no form to collect personal data, and the calculator runs in your browser — the amounts you enter are never sent anywhere.

Google Analytics 4 does run on every page, though. The tag itself writes nothing to your device — every storage signal, including analytics, is denied by default for every visitor — and because on an ordinary visit nothing is stored, no cookie consent is sought here. Google still receives an aggregated record from every page view: the page address, the page you came from, an approximate location derived from your IP address, and your device or browser type.

One exception is ours and is named here rather than passed over in silence: the gr_int flag, our own exclusion for internal visits. It is written only if 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. It holds a single flag and nothing about you, and you delete it by clearing this site’s data in your browser.

The final privacy policy, naming the controller and your GDPR rights, is being prepared.

The full content of this page is still being written.
