​Hi,

Thanks for your interest in Metronic.
If you purchase a license from <a href="https://1.envato.market/EA4JP">Themeforest<a/> you can use it for one project/deployment without needing to renew the license in the future. The license fee is paid once and used with no expiration.

​if your app does not charge the end users then you can go with the regular license, if you charge the end users as SaaS does, then you will need the extended license.

Regards.
