In general, cookies are used to store small bits of data, like if you leave a comment under one of the comics, you may opt-in to save your name and email address in cookies, or check whether you have a Gravatar avatar. Also, some anonymised data goes to Google Analytics, so I can see how many of y’all there are.
This is for your convenience, so that you do not have to fill in your details again when you want to leave another comment. And honestly, I don’t look at the ding-dang things at all. So feel free to disable cookies on this site if you want. It probably won’t make any difference in your experience here.
The most effective way to do this is to disable cookies in your browser. Check out the About Cookies website which offers help on this for all modern browsers. I personally use DuckDuckGo Privacy Essentials, they’re pretty good at it too. And if you want any comments you made previously to be removed, feel free to contact me.
Have a private day!
