So what’s the Fuzz about: Google’s Terms of usage of Adsense by any website owner who is a “publisher” to Google and publishing and using Adsense should have an adequate Privacy Policy on the sites they use Adsense.
Why is it required? Google Adsense could ban you as a publisher if you do not have a privacy policy on your blog or site as per Google states clearly in its privacy policy here
How to get a privacy policy: Now writing a privacy policy from scratch is not easy for everyone, basically when you are not from the legal department or cyber security profile. Now if you are a wordpress blogger there is an easy plugin that could help you by just installing and using the Easy Privacy Policy
Bonus: If you are not using Adsense on your website and you want to create a generic privacy policy for your website then you could use this article I have posted earlier on creating a privacy policy for your website
