Have you ever wondered how many sites have your credit card number?  Or, have you ever wondered how many sites have a certain version of your password?  Do you think you might have reused the password you have used on your banking Web site on another site?  What if you decided that you wanted to “clean up” your personal information on some of the sites where you’ve leaked this information.  Would you even know where to start?

If you answered “yes” to any of the above questions, then Appu is the tool for you.  Appu is a Chrome extension developed by  Ph.D. student Yogesh Mundada that keeps track of what we call your privacy footprint on the Web.
