Lifetime IDM license will work even if you decide to not pay for updates unlike one year license that stop working after one year.
You may not update IDM at all. Many users even now, when they have free updates option, use 2-3 years old IDM versions and are happy because they do not have tasks that require regular updates.

2. IDM one-year license
This license expires in one year after purchasing IDM. It means that IDM stops working and asks to enter a new product key in one year unless the license is paid and extended for another year. In general this license is one-time payment as well, unless you decide to make it a subscription during purchase process.
