YouTube allows you to embed videos with the possibility of not collecting information about the viewer unless he plays the video.
When you turn on privacy-enhanced mode, YouTube won't store information about visitors on your website unless they play the video.
To display videos in this mode, add the parameter cookie=off behind the permanent link as in example below. Also, do not forget to set autoplay to 0.
