[Solved] JD logs,cfg,archives explanation

Anonimity and privacy are serious concerns to me.

Jownloader is saving records of all my links and download activity in several different places on my computer; including log files and zip files. Perhaps also in other areas, as I have not found clear information on what information they are logging and where they are storing it.

Why would any one want this and how do I keep it from happening?

I'd also like to know where all my download information files they are leaving trails of on my computer are located so I can remove them.
