Privacy policy concerning the use of Google +1

Collection and dissemination of data:
The Google +1 button is a way for you to share information publicly with the world. The Google +1 button enables you and other users to receive personalised content from Google and our partners. Google stores the information that you have given for +1 content, as well as information about the page you were viewing when you clicked +1. Your +1s may appear to others as an annotation with your profile name and photo in Google services, such as in search results or in your Google profile, or elsewhere on websites and ads on the Internet.
Google will record information about your +1 activity in order to provide you and other users with a better experience of Google services. In order to use the Google +1 button, you need to have a public Google Profile visible to the world, which at a minimum includes the name you chose for the profile. This name will be used across all Google services and in some cases may replace another name you’ve used when sharing content via your Google Account. Your Google Profile identity may be displayed to people who know your e-mail address or other identifying information.

Use of the collected information
In addition to the above-described uses, the information you provide to us is also used in compliance with the currently valid Google Privacy Policy. Google may publish aggregate statistics related to users’ +1 activity or share these statistics with other users and partners, such as publishers, advertisers, or connected websites.
