Hey there. I'm Austin Haugen a product manager on the Facebook platform team.
A/ Instant Personalization uses the same set of APIs as the rest of platform. The only thing that changes with Instant Personalization, is that when you hit FB to see if the user is connected to your application, we will return 'connected' for all logged in Facebook users, who haven't opted out.
B/ Instant Personalization follows the same data policies as data you would get through a standard Facebook application. Details can be found here in section III: http://developers.facebook.com/policy/
Hey there. I'm Austin Haugen, a product manager on the Facebook platform team. If you opt out of Instant Personalization by following the steps above, you will never receive an instantly personalized experience on these sites and we also block the sites for you, so when your friends arrive your information will not be accessible. This was a change we made in May based on user feedback.
