Online Privacy Shield shows you the personal information that you're sharing with well-known web services (and any apps linked to them) such as Facebook, Twitter, Google+, Dropbox, Instagram, Yahoo, LinkedIn, Flickr, and Foursquare.
For each service analyzed the app indicates the type of shared data: basic information, location, access to media, inbox, contacts, and so on.
You can report some apps on trust or deauthorize those which are suspicious or invasive to your privacy.
