When you plug in your iphone to itunes can you see items in the apps?

Hi well yesterday i just updated my iphone and afterwards it put my phone into a weird connect to itunes thing. But the thing I'm worried about is that my dad needs to connect my phone to his computer and i have the spy calc app that has pictures that i don't want him to see. With the phone being connected to itunes would he be able to open the app to see what's inside? And with other apps would he be able to see account information at all? Any advice would be greatly appreciated!

No he won't be able to. He will be able to see what apps you have on your phone, but he would have to physically unlock the phone and open the app to see the photos, himself.
