Data Privacy Statement
With using my web site, you agree with data collection, data processing and data usage according to the following description. My web site can be visited and used without any registration. When doing so, the following data will be collected and saved in server log files on the web server for statistical purposes. This data cannot be connected to your person directly, as the IP addresses in the log files are anonymized:
- IP address (incomplete, last octet is anonymized)
- Date and time of request
- Requested file
- HTTP status code
- Size of requested file
- URI of requesting internet page (link where from?)
- Browser and operating system of requesting system (with what?)
This data will sporadically and exclusively locally be analyzed by me, to find faults and to optimize the web site accessibility and usability. Any collected data will not be given or transferred to any third party.
Analyzing Services like Google Analytics, Google AdSense and similar, which can track user behaviour and collect information about other web sites you visit, are not being used by my web site. Neither does the web site contain any social media buttons for Facebook, Twitter or similar, as these could also track user behaviour.
Personal data, particularly name or e-mail address, will only be collected and saved if you leave an entry in the guest book or if you write me a personal e-mail. When you leave an entry in the guest book, the name and e-mail address you specify will be visible publicly to other visitors. The data will not be given actively to third parties. The collected data, particularly name and e-mail addresses, will only be used for answering you when you contact me with a question, and they will not be shared with third parties.

I appreciate links to my site, I do not have any objections against deep-linking of single pages. I'd be thankful to get a short notice to the above e-mail addreass if you set any links to my site.
Technical issues:
All pages on www.buhla.de are completely free from active content, you get the full functionality without JavaScript or Active-X controls.
All pages are checked and approved for HTML 4.01 standard compliance by the validator of the W3 consortium – therefore you will find the W3C-HTML 4.01 logo on each page.
Barrier-free:
I tried to keep the pages barrier-free and usable for people with bad sight.
