For some cases facebook may need to access your private information. Facebook will use your private information that you post on your account, when you allow facebook to do that. Like your birthday information, if you set your birthday information will visible to all then facebook will send this information to all of your friends, and if you want to add some applications in your profile, facebook will inform you that it could be used for other propose.
Facebook has the right to use your data, but if you allow, only then it can be used. If you delete your account, facebook will also delete your all information automatically that you entered in your account. You can deactivate your account for 2 weeks, and if you do not facebook during this period, you account will be permanently deleted.
