Privacy options
By this time, most active Internet users have a profile on at least one social networking sites. While you can choose your privacy settings and limit the types of personal information that certain contacts can view, there are third-party applications which can access and collect your information. Once you give permission to the developers of these applications to view your personal details, it will not always be possible to find out what they will do with the information and to whom these will be shared, unless the uses are outlined and specified. Think twice before adding that app and keep your sensitive information to a minimum. You never know who’s looking.
