Google runs the play store. The play store requires a credit card. No one under the COPPA age can legally own a credit card. We should have been done there. And if we're talking purely gmail, a binding "please confirm you are over <age>. Note: this is a legally binding answer and Google reserves the right to delete your account if provided with incorrect information" should be more than enough. Google does not need a full date of birth. But boy howdy do they want it for advertisement purposes.

The Play Store doesn't require a credit card, at least not in the U.S. I have a Google account that I use for testing on an Pixel phone. When I go to install a new (free) app, it nags me to add a payment method to my account. But I can skip the prompt and download the app.

Play store requires a credit card to verify age for apps like tinder.

if you've never bought an app on the App store, you're not really using your modern pocket computer to its fullest. Most of the good apps, and good games, cost money.

(as they should)
