Protect your personal data away from third party app/Facebook
In April 2010, Facebook announced the launch of a platform called Open Graph to third-party apps. This update allowed external developers to reach out to Facebook users and request permission to access a large chunk of their personal data — and, crucially, to access their Facebook friends' personal data too. If accepted, these apps would then have access to a user's name, gender, location, birthday, education, political preferences, relationship status, religious views, online chat status and more. In fact, with additional permissions, external sites could also gain access to a person's private messages. To protect your personal data away from the third party developers, Simply follow the video guide below. As a developer strongly suggest mobile phone users use email to register for an unknown app or games.
