None of the sites privacy policies really differed that much. They all needed the same basic contact information: name, email, password. Some of the sites like sugarsync and box needed payment information and address. None share information with 3rd party websites. Most gave you the option to make your personal information exactly that; personal. They allow you and only you to see it or you can make some information public. Most all the categories in the privacy policy were almost exactly identical though.
