To help determine your age, we process the date of birth you provide. We also process information about your activity in our services, both when you’re signed in to a Google Account or signed out, and use machine learning technology to determine if you are likely over 18. In certain cases, if we cannot confirm that you are old enough to use our services by other means, we can request other information to verify your age, like your government ID, credit card, a photo of you, or your phone number.
