@aubrey @soderling They can save it, it's pointless, it's just a valid age verification token. The critical point is the authentication system that by law and governance, would be made in a way where you only authorise an age verification not sharing private data with the digital service OR logging on the government side what site you're trying to use. There are more technical steps available for privacy like key pairs, blockchain, owning your data I would prefer first but it is possible.
