YouTube Restricted Mode is a feature provided by Google. We offer our users the ability to enforce Restricted Mode by device. Google controls which videos are filtered by their Restricted Mode. We have no control over the content allowed or blocked by this feature, but can ensure the feature is locked on, if desired.
We do provide the flexibility to keep YouTube Restricted Mode locked on during certain hours, and then lift that restriction for a family device when you know a responsible adult will be there to monitor the content. So, the YouTube Restricted Mode lock feature acts as an extra layer of filtering safety to be utilized at your command, on a schedule, by device.
