I just saw this when I logged on:

European Union laws require you to give European Union visitors information about cookies used and data collected on your blog. In many cases, these laws also require you to obtain consent.

As a courtesy, we have added a notice on your blog to explain Google's use of certain Blogger and Google cookies, including use of Google Analytics and AdSense cookies, and other data collected by Google.

You are responsible for confirming this notice actually works for your blog, and that it displays. If you employ other cookies, for example by adding third party features, this notice may not work for you. If you include functionality from other providers there may be extra information collected from your users. 

 

FYI, I don't collect any information at all.  I don't have any third party features, or functionality.  AFAIK, no cookies or data is being collected other than what Google uses, and has stated above.
