Main Sequence Software offers a 30 day, no questions asked refund on all new subscriptions, re-subscriptions and unintentional renewals.  After 30 days from the date of purchase have passed, we will no longer provide refunds (prorated or otherwise). When a refund is issued for a new subscription, the account’s license keys will be deactivated.  When a refund is issued, for a renewal fee (existing subscriptions) or resubscription, your subscription expiry date will be reset to its original date before the refunded transaction.  Details about this can be found in our Terms and Conditions document that was (or will be) presented during the checkout and purchase process.
