Privacy policy

The figures you type into the calculator are processed on your own device — they are not sent to us and we do not store them. For general usage statistics the site uses Google Analytics 4, which collects aggregate visit data, never your salary. The site sets no advertising cookies and sells no data. There is one exception, and only if you ask for it: the gr_int flag, our own exclusion for internal visits. 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. It holds a single flag and nothing about you, and you delete it by clearing this site’s data in your browser.
