You can update your payment method and check your billing history from the Account page. While logged in, go to the Account page and click on the Billing tab. If you don’t see a Billing tab that means you are on the Free Forever plan so you have not been billed.
You can check and update which payment method you are using. You can change your payment method by clicking on the pen icon to the right of your payment information. You can delete your billing information at any time, but your account may lapse if you do not enter new payment details. If your account lapses it will revert to the Free Forever plan and features if you do not update your payment method.
