The problem remains though that, since the laws this feature was created to comply with put the onus on Google to verify the user's age and not on the device owner (e.g. the parents), the method they use to determine the user's age to feed into this API is terrible from both a privacy and freedom perspective: they force you to send them a copy of your government ID, and delete your account if you don't comply.[3]
