I assume you mean GA.
No, I meant piwik. In fact there are at least two types of cookies. One keeps track of repeat visitors, so it contains information on how you first entered the site. (A bizarre consequence is that piwik thinks I first entered my own site via Yandex search, because I happened to be trying something out :)) The other is the "do not track" cookie.
piwik unlike GA lives on your own site-- or at least one of them, if you're tracking multiple sites-- so there's no third-party cookie involved.
If scripting is off, all you get is the administrative gif. I don't think there's any way to disable this from the user end. But, of course, you're just giving the same information that's already in the regular logs.
