As per Google Notification every google adsense publishers should update privacy policy within 8th April 2009. So here i present a Sample Privacy Policy - Dart Cookie so that webmasters and blog owners can refer the format and create Privacy Policy.
DoubleClick DART Cookie is a cookie stored in clients computer to identify the interest of Browsers (Users). As google adsense plans to display interest based advertisements (ads), a cookie named Dart cookie will be stored on user PC.
So you have to notify this matter on your Website or Blog. So you need to update or create privacy policy.
Please refer Privacy policy of this website as Sample.
You can modify the contents of privacy policy of this website and include in your website, blog, blogger, blogspot, wordpress etc.
I dont know adding privacy policy is mandatory or not, but adding privacy policy to website or blogspot will give a professional look for your site or Blogger or wordpress blog.
Thank You.
