Just a couple of more things , few weeks ago i came to know the news that Facebook android app ( i myself don't use it ) have access to all of your SMS and MMS , and can send the emails to guests without the owner's' knowledge , so be careful using it (i think kaspersky revealed it )
also if someone had buyed any adobe product online from their credit or debit card their info has been leaked as their adobe accounts got hacked ( old news ) , almost half of them got hacked or maybe more...
And yeah respect the privacy .... the biggest con of internet is Privacy!
