A lifetime license is a one-time purchase — you own Foxel forever. It includes one year of updates, and you can add more years later with optional update extensions. Even if you don’t renew updates, you can keep using your current version indefinitely.
A subscription, on the other hand, is a recurring plan (monthly or annual). As long as your subscription is active, you always have access to the latest version and all updates. When the subscription expires, Foxel enters view-only mode — you can still open your files, but editing is disabled until you renew.
