2. Overview
This website is purely informational. We do not use any analytics or advertising tools, do not embed any third-party content, and load fonts and images exclusively from our own server. We only process personal data to the extent necessary to operate the website or to handle your enquiry.
3. Hosting and server log files
The website is hosted by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany. A data processing agreement pursuant to Art. 28 GDPR is in place with the provider.
When you visit the website, the server automatically processes the following data transmitted by your browser:
- IP address of the requesting device
- date and time of access
- page or file accessed
- referrer URL (previously visited page)
- browser and operating system used
This processing is necessary to deliver the website and to ensure its security and stability. The legal basis is Art. 6(1)(f) GDPR; our legitimate interest lies in the secure and error-free operation of the website. By default, the log files are deleted after eight weeks (about two months) at the latest, unless they are needed to investigate a security incident. IONOS anonymizes visitors' IP addresses in the log files.
4. Contact by email or phone
If you contact us by email or phone, we process the information you provide (such as name, company, contact details and the content of your enquiry) in order to handle your request.
The legal basis is Art. 6(1)(b) GDPR where your enquiry relates to a contract or pre-contractual measures. In all other cases, the processing is based on our legitimate interest in responding to enquiries (Art. 6(1)(f) GDPR).
We delete the data once your enquiry has been fully dealt with, unless statutory retention obligations apply, for example under commercial or tax law.
5. Cookies and storage on your device
This website does not set cookies and does not access information on your device that is not strictly necessary for the operation of the website (Section 25(2) of the German Telecommunications Digital Services Data Protection Act, TDDDG). Consent is therefore not required, and no cookie banner is displayed.
