With Google Play's billing system, you can safely and securely purchase digital products and in-app content, including subscriptions. Your payment information is securely stored to your Google Account and will not be shared with app developers. If you experience an issue with a purchase made through Google Play’s billing system, you can request a refund through Google Play.
In the United States, you can use credit or debit cards, mobile phone billing, PayPal, Google Pay balance, and gift cards as methods of payment.
To add a form of payment to your Google Play account, tap your profile icon, then select “Payments & Subscriptions” > “Payment methods.” Follow the instructions to add the payment method of your choice.
