Protect your data on FacebookHere are three ways to avoid sharing your personal information with advertisers and firms like Cambridge Analytics.
[MUSIC] If you're not ready to give up Facebook, here are three ways you can protect your information. Facebook now let's you delete anything from your timeline for good. This means it won't be able to share it with third parties. Go to Settings at the top right of your screen, next click on Activity log to see an over view of everything you've done on the social network in one spot and delete as you go. Android users beware. Facebook can collect information from your messages and conversations if you're not careful. Go to Settings and click on Apps > Facebook > Permissions and make sure telephone and SMS are off. And lastly set limits on advertisers. Go to Settings > Ads And your information. Here's everything advertisers know about, so opt out of what you don't wanna share. And don't forget your categories option, too. Under ad settings you can even control the type of ads you get targeted with on Facebook. In San Francisco, I'm Vanessa Hand Orellana, CNET.com for CBS News. [MUSIC]
