Enhance your privacy
Settings (Desktop) Click at the right of the top blue bar of any Facebook page and choose ‘settings’.
Click apps. Every app listed under the heading “log in with Facebook” has access to your data, which you can change by altering the permissions. You can also delete an app completely, though this doesn’t delete data the app developers may already have about you.
your information
Now click on Ads. You will see a “your information” bar which can be unfurled to show “about you” and “your categories”.
about you
Toggle every profile field in
“about you” to off where you don’t want to receive targeted advertising in those fields.
your categories
Now click on “Your categories”. This is based on your friends list, jobs and education information and location info, which Facebook uses to add you to categories for targeted advertising. You can manually delete the categories one by one.
advertising free
Below the “your information” bar is the ad setting bar where you can opt out of being shown advertising by certain parties by clicking “no”.
your account
Finally, go back to settings and click the privacy and timeline and tagging tabs in settings and check your account is as private as you’d like it to be.
