Charges other than the price
You need an internet connection to use the website and the API. Fees charged by your carrier or internet provider are paid by you. We do not charge shipping.
Payment method
Credit card, through Stripe Checkout. Trading Card Studio does not collect or store the full card number. Checkout and the customer portal are hosted by Stripe. From the dashboard, a paid plan or the Builder trial opens Stripe Checkout, and an existing subscription is managed in the Stripe customer portal.
When payment is charged
Paid plans are billed monthly in advance in US dollars and renew automatically each billing period. A Hobbyist subscription, and a Builder subscription that does not start as a trial, are charged when the subscription starts, at confirmation in Stripe Checkout. The Builder trial has no charge on the day it starts. A payment method is required before the trial begins. Unless you cancel before the 7-day trial ends, the Builder subscription starts automatically and the first charge is made then. Each account can start the Builder trial only once.
When the service is provided
This is a digital service. There is no physical shipment. After payment succeeds, API access for that plan, including the ability to create an API key, is available immediately. During a Builder trial, Builder access is available when the trial starts, before the first charge.
Cancellation and refunds
You may cancel at any time in the Stripe customer portal opened from the dashboard. Cancellation takes effect at the end of the current billing period. The plan stays available until that time. During a Builder trial, cancel before the trial ends if you do not want the paid subscription to start. We do not refund fees for a partial billing period, because the service is digital, except where the law requires a refund.
Operating environment
A current modern web browser, with HTTPS, for this website and the dashboard. The API is called over HTTPS at https://api.tradingcardstudio.com.
