Each child user profile may be associated with a Parent account or an independent account created by parent.

This information is typically collected through a variety of tracking technologies, including cookies, web beacons, Locally Stored Objects, log files, and all other similar technology (collectively, "all tracking technologies"), and we may use third party providers to collect this information on our behalf. These tracking technologies collect information about how you access and use the Service (e.g., referring / exit pages and URLs, how frequently you access the Service, the pages you view, the links you click, and other actions you take on the Service); information about your browser and information about the device(s) you use to access the Service  such as IP address, browser type, browser language, Internet service provider, device type, model and manufacturer, a unique ID that allows us to uniquely identify your browser, device or account, operating system brand and model, and whether you access the Service from multiple devices.
