With each request to bfluhr.com a log line is written to a log file. This logline records the first three bytes of your IP address (the least significant byte is omitted), the HTTP request method and the protocol’s version in use. It further documents the requested URL, the status code of the response, the number of bytes transferred with the response, the referer and your user agent. The resulting log files are then analyzed using Webalizer and while the resulting statistics may be kept indefinitely the original log files are deleted after at most five months.


My notes are available in different formats, one of them HTML. For the HTML version I use the MathJax CDN. If you access my notes in HTML your browser will make additional HTTP requests to cdn.mathjax.org which may in turn result in additional records about the transaction. Further MathJax makes use of cookies. If this is a concern I recommend downloading the PDF version instead. (The PDF and HTML versions contain the same content.)


If you use multidoc-rules with it’s default options for typesetting mathematical documents, then any time you build a document from scratch you download normalize.css from GitHub. Therefore GitHub’s privacy policy applies. Further multidoc’s HTML output references MathJax as well and thus the above applies to HTML files created with multidoc as well.
