Also identify any privacy practices mentioned: The LEGO Group offers to its users a range of sites, channels and applications, some of which are primarily targeted at families with users of all ages and others which are targeted at children. Our sites, channels and applications offer a variety of activities, including activities that may include collection of information from children. Below we summarize potential instances of collection and outline how and when we will provide parental notice and/or seek parental consent. In any instance that we collect personal information from a child, we will retain that information only so long as reasonably necessary to fulfil the activity request or allow the child to continue to participate in the activity, and ensure the security of our users and our services, or as required by law. In the event we discover we have collected information from a child in a manner inconsistent with COPPA's requirements, we will either delete the information or immediately seek the parent's consent for that collection."}, {'role': 'assistant', 'content': 'This clause is fair.
