In fact, you probably shouldn't be here, yet. If you're wondering about cookies and privacy and what not, we're not even up and running at present.
We use strictly the cookies necessary in order to allow the site to function; basically one token, including when a user is logged in. We don't have anyone else's cookies anywhere on this site at present. Before that changes we'll have our completed policy and consent form posted. At present, if you're not ok with us using our single functional cookie, then your option is literally to leave the site.
We don't share your information with anyone other than those entities with whom you interact while on our site, and even then it's only what you've set up to share with them: member name or alias, and any other optional stuff you include in your profile, specifically for sharing with our other members. We'll of course post a full privacy statement, cookie policy, and Terms of Service; but for right now, you know what you need to know. I mean, you shouldn't even be here right now. Go chat!
