01Subscription billing
Contributor membership is billed in advance each year. Founder membership is billed in advance each month. Paid memberships renew automatically unless canceled before the next billing date shown in your Kairn membership page or Stripe billing portal.
Each Founder payment also grants or extends Contributor access for 12 months from that payment. Ending Founder renewal does not remove that included Contributor access before its displayed expiry date.
02How to cancel
Open Dashboard → Membership → Manage billing and cancel the relevant subscription in Stripe's secure customer portal. Cancellation normally takes effect at the end of the paid billing period, and you may continue using the applicable access until that date.
Removing a payment method, deleting the Kairn account, or no longer using the service does not by itself cancel an active subscription. If you cannot access the billing portal, contact [email protected] from your registered email address before renewal.
03Refund eligibility
Membership fees are generally non-refundable once a billing period begins because digital access and capacity become available immediately. Kairn will review requests involving duplicate charges, unauthorized charges, an incorrect amount, or a material technical failure that prevented use of the purchased service.
Submit the request promptly with the account email, charge date, amount, and explanation. Approval is not automatic and may require verification. Any rights or remedies that cannot be excluded under applicable consumer law remain unaffected.
04Plan changes and failed payments
Canceling Founder renewal leaves the account on its remaining Contributor access after the Founder period ends. Canceling Contributor renewal leaves the account on Free access after the Contributor period ends, unless another valid entitlement remains.
A failed, disputed, reversed, or refunded payment may result in access being paused or adjusted and related platform benefits being reversed. Stripe and your payment provider may take additional time to return an approved refund.
