- Facebook doesn’t track everybody the same way. It uses different methods for members who have signed in and are using their accounts, members who are logged-off and non-members.
- The first time you arrive at any Facebook.com page, the company inserts cookies in your browser. If you sign up for an account, it inserts two types of cookies. If you don’t set up an account, it only inserts one of the two types.
- These cookies record every time you visit another website that uses a Facebook Like button or other Facebook plugin — which work together with the cookies to note the time, date and website being visited. Unique characteristics that identify your computer are also recorded.
- Facebook keeps logs that record your past 90 days of activity. It deletes entries older than 90 days.
- If you are logged into a Facebook account, your name, email address, friends and all of the other data in your Facebook profile is also recorded.
