Re: Question over studies of user choice re privacy/security and retention

Harry,
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.

Ilaria
