license purchase

Hi all,
my site is https://www.visurasubito.com
and I want to buy WooCommerce – Gravity Forms Product Add-Ons only for my site https://www.visurasubito.com with login credentials I use here….
without using wordpress org because I’m afraid that the license does not work then.
how can I do?
