Cookies are small text files that are stored on your browser or device by websites, apps, online media, and advertisements that are used to remember your browser or device during and across website visits. We also utilize other technologies that may identify you or the devices you use. For example, "pixel tags" (also called beacons) are small blocks of code installed on (or called by) a webpage, app, or advertisement which can retrieve certain information about your device and browser, including for example: device type, operating system, browser type and version, website visited, time of visit, referring website, IP address, advertising identifiers, and other similar information, including the small text file (the cookie) that uniquely identifies the device. Pixels provide the means by which third parties can set and read browser cookies from a domain that they do not themselves operate and collect information about visitors to that domain, typically with the permission of the domain owner. "Local storage" refers generally to other places on a browser or device where websites, ads, or third parties (such as HTML5 local storage and browser cache) can store information. "Software Development Kits" (also called SDKs) function like pixels and cookies, but operate in the mobile app context where pixels and cookies cannot always function. The primary app developer can install pieces of code (the SDK) from partners in the app, and thereby allow the partner to collect certain information about user interaction with the app and information about the user device and network information.
