How do I update my payment card?

In My Profile → Subscription → Payment method. This opens the secure payment portal, where you can add a new card, change the default one, or remove an old one. The change is applied instantly and will be used for the next charge.

Why this is done there and not in Kluppy: your card details are managed directly by the payment gateway. We never see or store your card number at any time, which is why the change is made in their portal and not on our own form.

If you have a pending failed payment, updating your card there usually resolves it on the next automatic retry.
