2. Data Collection on This Website

Server Log Files

The website provider automatically collects and stores information in server log files, which your browser automatically transmits. These are:

  • Browser type and version
  • Operating system
  • Referrer URL
  • Hostname of the accessing computer
  • Time of the server request
  • IP address

This data is not merged with other data sources. The basis for data processing is Art. 6 (1) (f) GDPR, which permits data processing for the purposes of our legitimate interests in ensuring the technical operation and security of the website.

Contact by Email

If you contact us by email, your inquiry including all personal data (name, email address, content of inquiry) will be stored and processed for the purpose of handling your request. We will not share this data without your consent.

The processing of this data is based on Art. 6 (1) (b) GDPR if your inquiry is related to the performance of a contract or is necessary for pre-contractual measures. In all other cases, the processing is based on our legitimate interest in effectively handling inquiries (Art. 6 (1) (f) GDPR) or on your consent (Art. 6 (1) (a) GDPR) if this has been requested.

The data you send to us via contact requests will remain with us until you request deletion, revoke your consent to storage, or the purpose for data storage no longer applies. Mandatory statutory provisions, especially retention periods, remain unaffected.
