We may also deliver a file to your browser or device (known as a “Web Beacon”) through the Service from an advertising network we have contracted with. Web beacons allow advertising networks to provide anonymised, aggregated auditing, research and reporting for us and for advertisers. Web beacons also enable ad networks to serve targeted advertisements to your browser or device when your browser or device visits other websites. These web beacons may, for example, log that you have viewed a certain product on our Service using your browser or device, and then show you an ad for similar products when you browse to another website. Because your web browser must request these advertisements and web beacons from the ad network’s servers, these companies can set, view or edit their own cookies, just as if your browser or device had requested a web page from their site. Many ad networks participate in the Network Advertising Initiative (“NAI”), a cooperative of online marketing and analytics companies committed to building consumer awareness and establishing responsible business and data management practices and standards, and such NAI Users may allow you to opt-out of cookies or web beacons they deliver. Again, we do not control the policies of any third parties, including advertising networks.
