Buy a plan
Choose a plan, enter your email and the domain of your shop. You then pay on Stripe's secure page; your license key appears here afterwards and is sent to your email. The plan renews every month: your card or payment method is charged automatically every month, in US dollars, for the monthly price of the plan you chose, until you cancel.
Cancel any time on the Manage your subscription page: no further payments are taken, and your license keeps working until the end of the period you paid for. Refunds: see the Refund policy.
No account and no password. Your license key comes by email; you manage your subscription with the email you bought with.
