I take the protection of your data seriously. This website is a private, non-commercial project. It uses no analytics or tracking services, no advertising and no marketing cookies. The following explains which data is processed when you visit this website.
1. Controller
The controller for data processing on this website within the meaning of the General Data Protection Regulation (GDPR) is the person named in the imprint.
2. Hosting and server log files
This website is hosted in Germany by: Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany. A data processing agreement according to Art. 28 GDPR is in place with the provider.
Each time a page is requested, the web server automatically stores information transmitted by your browser:
- IP address, which the hoster anonymises before storing it (the last part is replaced with a random value), so that it can no longer be attributed to a person
- date and time of the request
- requested page or file
- referrer URL (the previously visited page)
- browser and operating system
- HTTP status code and amount of data transferred
This data is needed to deliver the website and to ensure its security and stability, for example to detect attacks. The legal basis is Art. 6 (1) (f) GDPR (legitimate interest). Because the IP addresses are only stored in anonymised form, I keep the log files permanently and evaluate them statistically to learn how the website is used. The legal basis for this is also Art. 6 (1) (f) GDPR. The data is not combined with other data sources.
3. Cookies
This website sets only one technically necessary cookie:
- Session cookie (a random string as its name): required by the content management system Joomla for the technical session, for example for language selection and search. It is deleted when you close your browser and contains no personal data.
The legal basis is ยง 25 (2) No. 2 TDDDG (German Telecommunications Digital Services Data Protection Act), as the cookie is strictly necessary to operate the website, and Art. 6 (1) (f) GDPR. No consent is required.
4. Fonts and external content
This website does not load any fonts, scripts, videos or images from third-party servers. Google Fonts and other external services are not used.
5. Search
When you use the search function, the search term you enter is processed to show matching articles. Search terms are not linked to your IP address or other data. The legal basis is Art. 6 (1) (f) GDPR.
6. Links to other websites
This website contains links to other websites. These are ordinary links: the other site is only requested when you click a link. From then on, the privacy policy of the respective provider applies. No data is transmitted to these providers before that.
7. Contact by email or phone
If you contact me by email or phone, I process the data you provide (for example name, email address, phone number and the content of your message) only to handle your legal matter. The legal basis is Art. 6 (1) (f) GDPR. The data is deleted as soon as the matter has been settled and no statutory retention obligations apply. Requests that do not concern legal matters are deleted immediately, as described in the imprint.
8. Your rights
Under the GDPR you have the right at any time to:
- access the data stored about you (Art. 15 GDPR)
- rectification of inaccurate data (Art. 16 GDPR)
- erasure (Art. 17 GDPR)
- restriction of processing (Art. 18 GDPR)
- data portability (Art. 20 GDPR)
- object to processing based on Art. 6 (1) (f) GDPR (Art. 21 GDPR)
- withdraw consent with effect for the future (Art. 7 (3) GDPR)
To do so, please use the address given in the imprint. You also have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR), for example in the country or German state where you live.
9. Encryption
For security reasons this website uses TLS encryption (HTTPS). You can recognise an encrypted connection by the padlock symbol in your browser's address bar.
10. Changes
I update this privacy policy when the website or the legal situation changes. The version published here applies.
