Google ads have the ability to put the DART cookie on your web-browser. This is nothing to worry about, most likely you already have 100's of cookies tracking you every day. You can go into firefox privacy settings and "remove private data" and delete all cookies as well as manage your cookie profile.
I, Jacob Wagner, the owner of Zenchess.com will not specifically track any personal data about you other than what is tracked naturally through forums/chat rooms/etc. I will not be holding information about your email address or giving your information to spammers. If you have legitimate proof that I have given your information to spammers and can prove it in a court of law I will grant you the right to slap me (1) times.
All that being said, I plan to make Zenchess.com the coolest, most responsible, most awesomenessnessest website ever made. Thank you and goodnight.
