If your app's primary purpose involves content or products legally restricted to adults (alcohol delivery, tobacco/vape marketplaces, adult-only content), Google requires an active age-verification gate in addition to the correct maturity rating.
Commonly missed by apps that set the correct content rating in the questionnaire but never actually implement an age gate inside the app itself — a rating alone doesn't satisfy this policy.
"Your app promotes or facilitates access to age-restricted products without an adequate age verification mechanism, in addition to the required content rating."
Apps whose main purpose involves products or content legally limited to adults, such as alcohol delivery, tobacco or vape marketplaces and adult-only material, need more than the correct content rating. Google expects an active age-verification step inside the app. A rating alone does not satisfy the policy, which is why apps that fill in the questionnaire but add no gate are commonly flagged.
A rating tells people and stores how suitable an app is, but it does not stop a minor from using it. When the law restricts access to a product by age, the app has a responsibility to take reasonable steps to enforce that restriction. The policy turns a label into a control, so that apps dealing in age-restricted products are not simply available to anyone who installs them.
Mechanisms that go beyond a simple tap, appropriate to the product and region.
Content restricted to adults has its own rules and may need a gate.
It also covers certain content and functionality limited by age.
