Facebook is about sharing information with others —
friends and people in your networks — while providing you
with controls that restrict other third parties from accessing
your information. We allow you to choose the information
you provide to friends and networks through Facebook. Our
network architecture and your privacy settings allow you to
make informed choices about who has access to your
information. We do not provide contact information to third
party marketers without your permission. We share your
information with third parties only in limited circumstances
where we believe such sharing is 1) reasonably necessary to
offer the service, 2) legally required or, 3) permitted by you
(Facebook).
