All purchases at confdays.com via FastSpring (our reseller) are covered by our "14 days No Questions Asked Refund Policy". So we issue refunds for Confdays subscription within 14 days of the original purchase of the subscription.
Refunds are not applicable after 14 days from the date of your subscription purchase. That means refunds are not applicable on subscription renewals.
To request a refund, contact us via the support interface available in your conference website administration area and click on the dedicated link.
