If you want to opt out of your data being shared with Facebook, there are two ways you can do it. First, by unchecking the box you’ll see just above the ‘Agree’ button when you are asked to agree to the revised terms. Second, by going into Settings > Account > Share my account info at any time in the 30 days after agreeing the terms.
