Privacy policy

This page explains what personal data is processed when you visit this website, why, and what rights you have. In short: this website does not use cookies, does not measure traffic and does not embed content from other providers. The only data processed is what is technically required to deliver the pages.

1. Controller

Michael Engel
Rietheimer Str. 32
78050 Villingen-Schwenningen, Germany
Email: [email protected]

No data protection officer has been appointed, as there is no legal requirement to do so.

2. Hosting and delivery by Cloudflare

This website is hosted on Cloudflare Pages and delivered through Cloudflare’s network. The provider is Cloudflare, Inc., 101 Townsend St., San Francisco, CA 94107, USA. Cloudflare is a US company.

What data: When you open a page, Cloudflare necessarily receives connection data: your IP address, date and time, the requested URL, the amount of data transferred, the referring page (if your browser sends it), and your browser type and operating system.

Purpose: to deliver the website, secure the connection and fend off attacks.

Legal basis: Art. 6(1)(f) GDPR. Our legitimate interest is to provide the website reliably and securely.

Data processing agreement: Cloudflare processes this data on our behalf under its Customer Data Processing Addendum pursuant to Art. 28 GDPR.

Transfers to the USA: Processing may take place on servers in the USA and other countries outside the EU. Cloudflare is certified under the EU-U.S. Data Privacy Framework, so the European Commission’s adequacy decision of 10 July 2023 applies (Art. 45 GDPR). The data processing agreement additionally provides for the European Commission’s Standard Contractual Clauses (Art. 46(2)(c) GDPR).

Retention: We do not analyse or store access logs ourselves. Cloudflare determines how long it retains connection data; according to Cloudflare, this depends on the purpose of processing and legal obligations.

For details, see Cloudflare’s privacy policy: https://www.cloudflare.com/privacypolicy/

3. No cookies, no analytics, no third-party content

This website does not use cookies and does not store anything else in your browser. It uses no analytics or tracking tools and no advertising networks. It loads no fonts, scripts or other content from third-party servers; text is displayed in the fonts already installed on your device. Videos and other external content are linked, not embedded. Light or dark mode follows your device settings.

Search: The search function runs in your browser, which fetches parts of the search index from this website as needed. This only involves the connection data described in section 2.

4. Contact by email

If you email us, we process your email address, your name (if provided) and the content of your message in order to respond. The legal basis is Art. 6(1)(f) GDPR, or Art. 6(1)(b) GDPR for enquiries relating to a contract. We delete your message once your enquiry has been dealt with, unless statutory retention obligations apply. Emails are stored with our email provider, Proton AG, Route de la Galaise 32, 1228 Plan-les-Ouates, Switzerland, which processes them on our behalf (Art. 28 GDPR). The European Commission has recognised Switzerland as providing an adequate level of data protection (adequacy decision 2000/518/EC, Art. 45 GDPR).

5. Links to other websites

Articles link to sources on other websites. No data is transferred to those providers unless you click a link. Once you do, their privacy policy applies. Our links are set up so that your browser does not tell the destination site which of our pages you came from (no referrer is sent).

6. Your rights

You have the right to

• access the data stored about you (Art. 15 GDPR),
• rectification (Art. 16 GDPR),
• erasure (Art. 17 GDPR),
• restriction of processing (Art. 18 GDPR),
• data portability (Art. 20 GDPR).

Right to object (Art. 21 GDPR): You may object at any time, on grounds relating to your particular situation, to processing based on Art. 6(1)(f) GDPR.

To exercise any of these rights, simply email the address above.

Right to lodge a complaint (Art. 77 GDPR): You may lodge a complaint with a data protection supervisory authority. The authority responsible for us is:

Der Landesbeauftragte für den Datenschutz und die Informationsfreiheit Baden-Württemberg (State Commissioner for Data Protection and Freedom of Information of Baden-Württemberg)
Postfach 10 29 32, 70025 Stuttgart, Germany
Website: https://www.baden-wuerttemberg.datenschutz.de

7. Obligation to provide data; automated decisions

You are not obliged to provide any data. Without the connection data described in section 2, however, the website cannot be delivered. No automated decision-making or profiling takes place.

8. Changes

If the website or the services used change, we will update this policy. The version published here applies.
