Facebook has been trying to pacify users over privacy issues that have cropped out on the most popular social networking site in the world.
Late last month, Facebook had unveiled simplified privacy controls for users, and today they have rolled out new simplified permissions for third-party applications that need to access your data on Facebook.
As you can see from the above image, third-party apps will now clearly mention what type of information they will access and ask you to grant permission to them. According to Facebook, the application will only be able to access the public parts of your profile by default. To access the private sections of your profile, the application has to explicitly ask for your permission.
This makes it really transparent and easy to understand as to what information is being shared with third-party apps. If you do not want information to be shared with apps or with search engines, you can change your privacy settings here. More info on this at the official Facebook blog.
