If customers experience difficulties that are caused by problems within the control of ecocalc.com or its hosting provider, the normal course of redress will be to reactivate the customer's subscription. ecocalc.com will only reactivate subscriptions in the cases where its records show that the simulation did not complete for reasons within the control of the ecocalc.com or its hosting provider, providing the visitor notifies (as per instruction in the welcome email sent at the time of subscription) ecocalc.com of the problem within 7 days of the subscription.

ecocalc.com will not store the simulation results for a period longer than one month. However, it will store the simulation set-up data for a period of 6 months, or longer by special request.

ecocalc.com will not refund subscriptions in cases other than where the simulation did not complete for reasons within the control of the ecocalc.com or its hosting provider, providing the visitor notifies (as per instruction in the welcome email sent at the time of subscription) ecocalc.com of the problem within 72 hours of the subscription and there is a verifiable reason rendering the reactivation of the simulation valueless to the visitor.
