Privacy Policy


No cookies. No analysis. No tracking. Server logfiles only (max. 5 days). Server location: Germany.


This website is provided by a web server of a provider. This provider stores the following log data when an HTML page is called or a file is downloaded. I am not interested in these logfiles and they are only needed in case of DDoS attacks or similar situations. The default is: The logfiles are deleted unseen. If there are open questions, a short e-mail is sufficient. The e-mails are also deleted if they are not longer needed. Emails are automatically deleted (via a script) after 14 days unless I archive them.

The storage period of these logfiles are normally 14 days. I think that is too long. Therefore I have reduced the period of storage to 5 days.

Content of Logfiles:

  • Your IP-Address (
  • Date/Time (29/May/2020:18:16:57 +0200)

  • User-Agent (Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:77.0) Gecko/20100101 Firefox/77.0)
