In most (all, I think) US, contracts with children are generally legally valid, but voidable by the child. This means the child (or the child’s guardian) mau cancel the contract before performing any obligation. It does not mean that once completed, the exchange can be retrowctively invalidated, though.
It’s presented as a contract mutually agreed between you and the service provider - you get the service; the provider gets the data. A legal contract.
But, in all systems of law that I’m aware of, you can’t make enforceable contracts with children.
This exists as a way of protecting children from making disadvantageous agreements that they don’t yet have competence to understand.
So, the service provider can’t use any contract as justification for handling personal data of children.
This leaves the service provider without legal justification and then calls their ethics into question.
