This is solely for AdSense publishers. Everyone knows Google and DoubleClick have a venture together, so here are the changes for AdSense publishers in their privacy policy.
It’s all about the cookies set by DoubleClick ads for visitors. All you have to mention is that:
Google is a third-party vendor of your site that uses cookies to serve advertisements on your site.
Google’s use of the DART cookie enables it to serve ads to your users based on their visits to your sites and other sites on the Internet.
Users may opt out of the use of the DART cookie by visiting the Google ad and content network privacy policy.
Just update your site policy to avoid hasty decisions from Big G.
