How many sites can I use the theme or plugin on?
As many as you like. The plugins and themes are 100% GPL licensed so you can use them as often as you like on as many sites as you like.
Do you provide updates to the items?
Yes! The items are daily updated. After I am notified about an upgrade, I download it from the original authors and update it on the website. Provided that you have an active subscription then you’ll have access to the upgrades.
