When this site runs in subscription mode with Stripe enabled, you complete payment on Stripe’s secure checkout page. Depending on your device and region, you may see Apple Pay, Google Pay, Link, or card fields — Stripe decides which methods to show.
Credits from your membership are added after Stripe confirms each invoice (first payment and renewals). You can buy extra credits from Profile when the operator has the Stripe credit shop configured.
Cancel or update your card: after you have subscribed, use Profile → Manage subscription & payment to open Stripe’s customer portal (the operator must enable the portal in their Stripe Dashboard).
