Hello,
Thanks for using XStore.
As we can see, our theme is used on https://zini.cc/
According to the ThemeForest license policy, you can use 1 license for 1 project only (dev site, production site, localhost but the same project) – https://themeforest.net/licenses/terms/regular
If you want to use our theme for a few projects you need to buy a few licenses.
Regards
