All our licenses are perpetual. They come with 1 year of software updates and technical support. Afterwards you can use the last editor release that was available to you for lifetime without any extra payments, but you will no longer have access to the latest software updates.
If you wish to continue getting the latest software updates, you can choose to renew the license, and if you do so 1 month before the update rights and support period expire, you will get a 25% discount off of the prices listed on our website at the moment of renewal.
