Privacy policy

Principle

Protecting your data matters to us. This site is deliberately data-minimising: the calculators run entirely in your browser, and your inputs are neither transmitted to us nor stored.

Controller

The controller under the GDPR is the provider named in the legal notice.

Server log files

When you access the site, the hosting provider processes technically necessary data (e.g. IP address, time, page requested, browser type) to deliver and secure the site. The legal basis is Art. 6(1)(f) GDPR. The server is located in Germany.

Fonts

Fonts are served locally from our own server. There is no connection to third-party servers such as Google Fonts.

Analytics (only with consent)

For anonymous reach measurement we use the self-hosted software Matomo — only after your explicit consent. Without consent, no analytics script is loaded and no access to your device takes place (§ 25 TDDDG). The legal basis is Art. 6(1)(a) GDPR. You can withdraw your consent at any time with future effect by clearing your browser’s site data.

Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and objection, and you may lodge a complaint with a data protection authority.
