The My Account area allows you to view your current subscription status and purchase, renew, or extend subscriptions. You can also sign out or in to your NC Software account, the same used to login to http://nc-software.com/MyAccount to sync with Logbook Pro Desktop. If renewing/extending a subscription Apple may advise you that you already purchased this subscription. You can ignore this message and proceed as NC Software will base your renewal on the expiration of your current subscription. There will be no overlap at any time so renew as you desire.
We recommend renewing and extending subscriptions from NC Software's web site and NOT in-app by visiting http://nc-software.com/subscriptions. Purchasing from other than NC Software does not give NC Software any control to assist you with purchase issues as the sale is between you and the vendor. When NC Software holds sales they only apply for purchases made from NC Software and not from in-app purchases as there is no provision for entering coupon discount codes from in-app via 3rd party vendors.
