LockJar basically watches your Cookies directory and interrogates any changes made to it. I've broken cookie types down into four distinct categories: Spy Cookies, Suspects, Session, and Edible (OK). Spy Cookies are from websites that have been known to use gathered information to better suit their advertising amongst other things. Any cookie designated as a Spy Cookie will be promptly removed from the cookies directory by LockJar as soon as it is written. I include a small database file that includes the Spy Cookies that I currently know of from reading information on Internet Privacy sites. With LockJar, you can designate any cookie found in your cookies directory as a Spy Cookie and these will then be removed as well when they are written. Session cookies are ones that you determine to not necessarily be a spy, but you don't want it left on your machine either. These types of cookies will be deleted when LockJar is shut down (either by the user shutting it down or during shutdown of Windows). Suspects are cookies that LockJar does not know about or ones that have just been added to your cookies directory. When LockJar first starts up (given that you have the update option marked) it will interrogate your cookies directory and update the central grid with all cookies that it doesn't know about. Edible (OK) are cookies that you have designated as being trusted. These cookies will remain untouched.
