PATorganiser is a subscription based product. When you cancel your subscription, you will be able to finish out your paid term, but your account will not auto-renew. For example, let’s say you have a Monthly subscription and your purchased it on January 1 2017. Come July 15, 2017, you decide you don’t need PATorganiser at the moment. If you cancel your subscription, then your auto-renewal stops. BUT you will still be able to use PATorganiser for the remainder of July. This is true for annual licenses as well, except in those cases your term is a year.
