Does jmix need to be online to keep annual license active?

I understand jmix needs to be online at the time of license activation. My question is because I need to be offline for 6 months. I ask to find out if it works somehow like Microsoft Office, that needs a least one connection to the license server every 90 days.

Yes, Studio needs to be online when the subscription is prolonged, to get the new expiration date.
If you expect to be offline that time, it’s better to prolong the subscription to the required period beforehand, while you are online.

There are other options too, so please drop us an email at and we’ll arrange the prolongation conveniently for you.
