Application Privacy
Many of you are annoyed to find friends to talk about all the things they’re doing, which is why Facebook makes it immediately clear that you can set the privacy settings for each application. In the dialog box it is clear who can see it :

You can then choose to only close friends can see what music you are listening, or if anyone can see that you are practicing a sport, if only a few friends (the “Custom) can see what you are reading or cooking, and so on.
The list of applications you have added to the Timeline, with their privacy settings are available at your account settings, the applications tab.
And the games?

The games behave like applications, and are shown in box on your Timeline and is communicated to your friends (or whoever you want) when you are playing. The full list of games (and requests for applications) can be found on the dashboard: http://www.facebook.com/games
