Simple Card Sort is a subscription based service. You pay to use the service for a period of time. During that time you can create unlimited card sort projects, and have an unlimited number of participants for your card sort - once your subscription ends, participants will not be able to complete the card sort. After your subscription ends you can still access your card sort project and results information.
We have chosen PayPal for all payment processing. For your protection we do not store any credit card information - only confirmation of payment. Time purchased on an already active account will be added to the end of your current end date.
Subscriptions do not renew automatically.
