 ## Cookie Privacy
 
-Prebid websites don't set their own cookies, but vendor products we use do. So we use the OneTrust CookiePro library to pop up a cookie banner. If the user hasn't consented to setting cookies, they will find reduced functionality on the site -- they won't be able to view JSFiddle examples or example videos.
