Incognito window + proxy (just because) + only looking at it behind a locked door or in an empty house = Win
Oh, and about the stuff already on my computer- You need to get through the face recognition and a password to access my account, then you need to locate my stash buried deep in a web of folders, rename a certain .jpg to a .rar, then know the password to that rar file. Then, another web of folders later, you're there!
(I once forgot where I put it and the password for it... took me 2 months to find it and get into it. Well, if I can't find it, they can't find it, right?)
