Premium is a membership billed monthly or annually at the prices shown on the pricing page. It is separate from the one-time $499 Portfolio Checkup.
Your plan status — active, trialing, past due, in its grace period, ending at the period end, expired or free — is read from the shared account service and shown on your account page. We never decide your plan from a web address, a saved browser value or a payment-confirmation screen.
No Premium payment price is authorized for this app yet, so upgrading shows a truthful 'not available yet' state instead of a checkout that would fail. Nothing is charged.
When Premium billing opens, payment, renewal, cancellation and refunds are handled by the shared payment service. Cancelling keeps access until the end of the period you already paid for.
