2. Calculators

All calculations run locally in your browser. The numbers you enter are not transmitted to us or stored by us. We do not use cookies, analytics, advertising or tracking tools, and we do not load fonts or scripts from third parties.

3. Hosting and server log files

This website is hosted on Cloudflare Pages, a service of Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA (“Cloudflare”). When you visit the site, Cloudflare technically processes your IP address and request data (date and time, page requested, referring page, browser and system information) to deliver the website and protect it against attacks and misuse. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in a secure and reliable website). Cloudflare acts as our processor under its data processing addendum (Art. 28 GDPR). Data may be transferred to the USA; Cloudflare is certified under the EU-U.S. Data Privacy Framework (adequacy decision, Art. 45 GDPR) and otherwise relies on standard contractual clauses (Art. 46 GDPR).

Retention: Cloudflare stores this data only as long as necessary for these purposes. We do not use Cloudflare Web Analytics or any other analytics, and we do not evaluate access logs. Further information: Cloudflare privacy policy.

4. Links to shops

Some pages link to our products on the external platform Gumroad (Gumroad, Inc., USA). Data is only transferred to those platforms if you click a link; their own privacy policies apply there.

5. Contacting us

If you email us, we process your message to answer it (Art. 6(1)(b) or (f) GDPR) and delete it when it is no longer needed, unless legal retention obligations apply.

6. Your rights

You have the right to access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR), and the right to lodge a complaint with a data protection supervisory authority, for example the authority responsible for us: Die Landesbeauftragte für den Datenschutz Niedersachsen, Prinzenstraße 5, 30159 Hannover, Germany.
