How can I make my Facebook profile completely private?
I don't want people to be able to see me.
Go to your privacy settings page and change everything to
Friends. Each of the sections have areas that need to be changed:
Friends for each of the three choices)
Friends for each of the three choices with drop downs
Friends within each of the settings or remove apps that you don't want to use
Your name, gender, username, and user ID (account number), along with your profile picture, cover photo, and networks (if you choose to add these) are available to anyone. This is because this information is essential to helping you connect with your friends and family.
So anybody can see those details—your friends, friends of your friends and pretty much anybody who has the direct link to your account. And if you didn’t turned off the public search feature, anybody who finds your profile by searching you on a search engine (e.g. Google).
