What does Operating-system user profile mean?
An operating-system user profile is a platform-level environment for a device user, distinct from an account label inside one player. Where supported, it can separate a broader collection of app data and settings rather than only a content-source selection.

Availability and privacy boundaries differ across phones, televisions and computers. Do not assume a television device offers the same multi-user controls as an Android phone. A device owner may still have administrative access, so borrowed hardware is not an ideal place to retain sensitive credentials. Review platform family settings separately from player parental controls.
