4. Server log files

Each time the website is accessed, your browser transmits technically necessary data to the server. The following is stored:

• the IP address, shortened before it is stored: for IPv4 the last byte is replaced with 0, for IPv6 only the first 32 bits are kept;
• date and time of access;
• the page or file requested, the status code and the amount of data transferred;
• the previously visited page (referrer), if your browser transmits it;
• browser type and operating system (user agent).

Purpose: secure and stable operation of the website, error analysis, prevention of misuse and aggregated visitor statistics (for example page views per day and page). The statistics use no cookies and create no user profiles.

Legal basis: Art. 6(1)(f) GDPR. My legitimate interest lies in the purposes stated.

Retention: The log files are deleted automatically after 7 days at the latest. The statistics contain only aggregated values, no IP addresses.

5. Contact by e-mail

If you send me an e-mail, I process your details (e-mail address, name if given and the content of the message) to answer your enquiry. The legal basis is Art. 6(1)(b) GDPR if your enquiry relates to a contract, otherwise Art. 6(1)(f) GDPR (interest in answering enquiries). I delete the messages once they are no longer needed, unless statutory retention obligations apply.

My mailbox is provided by GMX (1&1 Mail & Media GmbH, Brauerstr. 48, 76135 Karlsruhe, Germany).
