So far so good! – MyPermissions Privacy Cleaner Review

Not sure what happens after 90 days, but for now it helped to remind me of apps that I had granted permissions to on Facebook that shouldn't need them anymore. Took my Facebook from 100% at risk to 0%. I don't use Twitter, Google+ or Dropbox, so I can't rate it based on those. So the 5* covers Facebook only.
