“Web Beacons” (also known as web bugs, pixel tags, or clear GIFs) are tiny graphics with a unique identifier that may be included on our Services for several purposes, including to deliver or communicate with Cookies, to know if a certain page was visited or whether an email was opened, to advertise more efficiently by excluding our current users from certain promotional messages, to identifying the source of a new installation, to delivering ads to you on other websites. Unlike Cookies, which are stored on the device, Web Beacons are typically embedded invisibly on web pages (or in an email).
