Facebook – How much data do Facebook applications have access to

facebookprivacy

When I allow an application to access my data, what information can it actually access?

Best Answer

It used to be that applications had full access to all your data, but now it's more restricted:

instead of granting access to all of their profile data when engaging with an application for the first time, users will now authorize only specific categories of user data – like interests, gender, or their current city, for example. With the changes, when developers want to access new profile information fields not granted in the original application authorization, they’ll need to ask for explicit permission.

So the application should ask you for permission and tell you which categories of data it wants access to. So if you're not happy about letting an application having access to your photos, for example, you should be able to tell and not install it.
