"We may deliver a file to you through the Services (known as a "web beacon") from an ad network. Web beacons allow ad networks to provide anonymized, aggregated auditing, research and reporting for us and for advertisers. Web beacons also enable ad networks to serve targeted advertisements to you when you visit other websites. Because your web browser must request these advertisements and web beacons from the ad network's servers, these companies can view, edit, or set their own cookies, just as if you had requested a web page from their site."
Third-party ad networks can set their own cookies and track users via web beacons embedded in the service. FunCraft also shares data with affiliated businesses, agents like Google Analytics, and advertising partners.
