Privacy policy

As of 10 November 2026

In short:
  • No account, no login, no cookies, no analytics, no advertising.
  • Your salary and all other inputs are calculated only in your browser. They are never sent to us or to any server.
  • Your inputs are kept in your browser's session storage only so that the four pages can share them while you click around. They are deleted automatically when you close the tab or window.
  • We don't count or log visitors – and our host doesn't record IP addresses either.
  • We know nothing about who you are or what you entered.

1. Who is responsible

[Name, postal address and e-mail of the site operator – to be added before the site is shared publicly]

2. What happens to the data you enter

All calculations (taxes, social insurance, charts, the past and future comparisons) run as JavaScript on your own device. No form is submitted and no input is transmitted over the network.

To keep your inputs when you switch between “Overview”, “Past”, “Now” and “Future”, the site writes them to sessionStorage in your browser (keys salaryState and lang). This storage is not a cookie, is never sent to a server, is only visible to this site in this tab, and is erased by the browser as soon as the tab is closed. You can also clear it at any time by closing the tab.

3. No third-party services

The site loads no external fonts, scripts, trackers or embedded content. All charts are drawn by the site's own code, and the map of the German states is delivered from this site itself. Links to sources (e.g. the Bundestag or the Federal Ministry of Finance) are only opened when you click them; from then on the privacy policy of that website applies.

4. Hosting

The site is hosted by statichost.eu (Variable Object Assignment, c/o Knackeriet, Svartmangatan 9, 111 29 Stockholm, Sweden). Processing takes place within the EU/EEA.

To deliver the pages, the host's servers necessarily process your IP address for the duration of each request. According to the provider, visitors' IP addresses are not logged, no personal data about website visits is stored and no third-party processors are used for website data. We therefore have no access logs and do not count or track visitors. All pages are delivered encrypted (HTTPS). The values you type into the calculator are not part of these requests.

Legal basis for this technically necessary processing: Art. 6(1)(f) GDPR (legitimate interest in providing a working, secure website). [Data processing agreement with the host: to be concluded]

5. Your rights

Under the GDPR you have the right to access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR). Because we do not store any personal data about you, there is usually nothing we can show or delete. You also have the right to lodge a complaint with a data protection supervisory authority, e.g. the Berlin Commissioner for Data Protection and Freedom of Information.

6. Changes

If a feature is ever added that sends data to a server or counts visits, this policy will be updated before the feature goes live. Any such transfer would be encrypted, stored only for as long as the calculation needs it and deleted immediately afterwards.
