No trackers. You’re as anonymous as someone using the Internet gets. The site is written in HTML/CSS/PHP and currently has no need to know who you are. It might start storing session information (keeping track of currently open connections to it) in order to show alternate appearances correctly, when I sort out how to enable those, but right now it doesn't even do that.
There will be a login cookie eventually, but that’s a long way down the road, and it’ll be very clearly flagged.
