Artbees is an exclusive Envato author, so the Jupiter theme license follows the Standard licenses. The only point is Jupiter has become GPL licensed and Extended license is not available now.
In this article, we explain the Regular license for the Jupiter theme.

Regular License
Almost all users need to buy this type of license for use on a single domain. You can read more about the Regular License on the ThemeForest website.
License Registration in the Artbees Portal
Upon theme purchase from ThemeForest, you’ll receive a license key. Use the key to generate an API key for theme registration in the Artbees portal.
Artbees API allows you to register your theme only on a single domain (including subdomains and subfolders).
