Two subscriptions options are available: one year and VIP.
One year means that you can download new program versions in the course of the year after the purchase. After the one year you can either continue working with the latest version your subcription allows, or prolong it, or uprade it for the VIP type. If you lose your setup after your subscription is over, we will provide a link for the program version your subscription allows.
VIP license is one time payment for all future versions. It is the best option if you like the program and our tech support, because we constantly develop it.
