I think for the country I live in, most of this isn't even legal.
I suspect your argument would be that none of the information you keep on these minors is of the type that could be exploited. If that's the case, then the policy is extremely misguided, and says a lot that doesn't need to be said in such haphazard terms.
There is a heightened level of diligence that needs to be put into a service that caters to minors. This needs to be aligned with something that can be underwritten, or it is potentially very harmful.
I didn't look deeply at anything else on offer, because this was a full-stop right off the bat. Your policy shouts "Stranger Danger" big time. The rest looks fine and really useful, but not worth looking at under such a policy.
The intent is to create a friendly environment for kids 13+ where their privacy is fully protected!
There is no plan to take away privacy while using the service. The verbiage will be revisited. Thanks again for this constructive feedback.
