Privacy

The calculator

The calculator runs in your browser. The wages and days you type are not sent to us or to anyone else and are not stored. If you use “Copy link”, the figures are written into the address of the page so that you can share it; they leave your device only if you send that link to someone.

The site remembers your choice of light or dark theme in your browser (local storage). Nothing else is stored on your device by us.

Cookies and visit counter

To count visits we use GoatCounter, a privacy-friendly counter: it sets no cookies and stores nothing in your browser, builds no profiles and does not store your IP address, your full browser signature or any identifier. It keeps only aggregate numbers (page, hour or day, browser, country, screen width) on servers in the European Union and shares nothing with third parties; see GoatCounter's privacy policy. The visit counter uses no cookies; the advertising described below does.

Advertising (Google AdSense)

This site shows ads served by Google AdSense. Google and the advertising partners it works with use cookies and similar technologies (such as advertising identifiers and your browser's local storage) to show ads, limit how often you see the same ad, measure results, prevent fraud and, only if you allow it, personalise ads based on your visits to this and other websites. For these ads Google is an independent controller of the data it collects.

If you are in the European Economic Area, the United Kingdom or Switzerland, a consent message appears on your first visit. It is Google's own certified consent management platform (Google “Privacy & messaging”, certified under the IAB Transparency & Consent Framework): advertising cookies and identifiers are used only with your consent, and you can change or withdraw your choice at any time from the privacy and cookie settings link that the message leaves on the page. If you say no, you may still see ads that are not personalised. The legal basis is your consent (Art. 6(1)(a) GDPR and the ePrivacy rules on cookies).

How Google uses information from sites that show its ads: policies.google.com/technologies/partner-sites. You can turn off personalised ads from Google at any time in Google's ad settings. Google may process data outside the EU with the safeguards required by the GDPR.

Hosting

The site is hosted on Netlify, which processes technical data (such as IP addresses) to deliver pages and protect the service.

Corrections form

If you use the corrections form, we receive the page you name, your message, the source link and, only if you give it, your email address. The form is processed by Netlify Forms on our behalf. We use what you send only to check and answer the correction, and keep it only as long as that takes. The legal basis is your consent, given with the tick box; you can ask us to delete your message by sending another one through the form. There are no accounts or newsletters on this site.
