I don't collect any personal information about this website's visitors.
I use some third party services that may set cookies. In particular, I use Google AdSense (to display ads) and Google Analytics (so I can see how much traffic the website receives, pages visited, the numbers of visitors from different countries, etc). These services provide aggregate data, and I do not collect any personal information about this website's visitors from those services.
You can also choose to disable cookies using your web browser's settings. If you do choose to disable cookies, some parts of this website (and other websites) may not work as expected.
As with most websites, data is collected in the web server log files. This is a commonly accepted practice and includes data such as web pages requested, date and time of request, the type of web browser used, the visitor's IP address, the web page that referred the user to this website (if any), etc.
This information can be used for determining things such as how popular the website is, whether traffic is increasing or decreasing over a period of time, which pages visitors find useful, the websites the traffic is coming from etc. It can also be used for diagnostics purposes (for example, troubleshooting an error), and it can be used for security purposes (for example, analyzing unusual traffic in the event of a DDOS attack, etc).
