We have done studies related to users's choices for smartphone apps. We found that people change their mind once they understand the kind of data that is accessed [1], [2].

You might also want to check some of Adrienne Porter Felt, Lorrie Cranor (nudges), Acquisti and Jennifer Goldbeck' s research since they are also relevant. 

I hope it helps.
