Airtame licenses are set to automatically renew at the end of the subscription cycle. If you have canceled your subscription, then your licenses will be removed and you will need to buy new ones to get access to licensed features again.
Note: Airtame is using a licensing mechanism so our customers will have fewer administration headaches. The system calculates the total days per licensed device. This means that next time you need to renew your subscription, you will need to do it once instead of per device.
