"Facebook on Friday released its Android launcher called Home. The company also updated its Facebook app, adding in new permissions to allow it to collect data about the apps you are running. Facebook has set up Home to interface with the main Facebook app on Android to do all the work. In fact, the main Facebook app features all the required permissions letting the Home app meekly state: 'THIS APPLICATION REQUIRES NO SPECIAL PERMISSIONS TO RUN.' As such, it’s the Facebook app that’s doing all the information collecting. It’s unclear, however, if it will do so even if Facebook Home is not installed. Facebook may simply be declaring all the permissions the Home launcher requires, meaning the app only starts collecting data if Home asks it to."
