Thank the limitations of the HTTP protocol.
I hate cookies, so I do not manually utilize them myself. Instead, I use server-sided sessions which essentially "identify" a visitor by their browser or client's user-agent and IP address. This is done to save any preferences that you may (or may not) select during your visit to the site, such as the website's language or its display mode. Unfortunately, due to the limitations of the HTTP protocol, sessions are stored on the client in the form of a cookie.
While there are a couple of alternatives to using cookies to store the server-sided sessions, they pose a far greater security risk and are far less reliable. Unless and until a better solution becomes available, I am afraid there is nothing else I can do. So if you have an issue with cookies, you can either disable them via your browser, or simply deal with it.
Collection of Personal Information
Seeing as there are over 7.7 billion people on planet Earth, any of which could be visiting this site at any given time for any particular reason, I could truly care less who each person is. I appreciate your visit, but I will not make it my mission to find out your life biography just because you visited my site. Even if I wanted to, I do not possess the resources to even do such a thing.
The only data collected from your visit to this website is the standard information that is transmitted via the TCP/IP and HTTP protocol. This will always include your IP address as a bare minimum, and will usually include other supplemental information such as a user-agent string that identifies your browser and/or client. This information is usually logged to an operational server log, along with an HTTP status code that indicates result of whether or not the request could be successfully served or not.
The aforementioned data above may be tracked for purposes of website analytics, to help me get a better understanding of the traffic of the website. For example, I may wish to see the page with the highest number of visits, or wish to see what page(s) visitors spend the most time on. This data is something only I can view; it is not sold or redistributed to anyone else. This website does honor the "Do Not Track" request that can be sent with most browsers. If you do not wish to be tracked, please be sure to configure your browser as appropriate.
