ok clever clogs..
it says..
So does that mean you have to set whether it targets children on a country basis?
If your app doesnt target children, i guess you cant really stop a kid using it.
So if you have 20 games/apps on the store you have to complete the section regardless if if you target kids?
This is a huge deal then, so even if you specify 18+ for your target audience they can decide that your icon or screenshots appeal to children and stop you updating your app?
There's really not much that can be said about this.
Targeting children in one country but not in another is nonsense. You know your target audience, and you know whether it includes children. If it does, it's your responsibility to keep your app suitable for children.
Whether children end up using your app even though they're not part of the target audience is irrelevant and the responsibility of their parents, not yours.
What you have to specify where is not something the GMC can tell you. It's a question for the platform you intend to publish on, so you should ask it over there.
If you're unsure about your app being suitable for children, do as you were instructed on the page you linked and consult your legal counsel, not the GMC.
