Where parental controls exist, give the child age-appropriate information that they are in place, and where parents can monitor activity or track location, give the child an obvious sign (such as an icon) when monitoring is active; also give parents material explaining the child's UNCRC privacy right and resources for age-appropriate discussion, with materials varying by age band.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
