On your Facebook account, head to the settings cog in the top right corner of the screen, click on Privacy Settings, then Who can see my stuff, then click friends. This way only your nearest and dearest should have access. With Twitter, go to the settings cog, then Settings. In this window, you’re able to change all kinds of privacy settings, including making tweets private so only people you allow to view your tweets can see them.
