License depends on subscription plan that you purchase:

Basic – Full plugin that can be used only for one domain or project – price $59.

If your multiple sites are sub-sites of the same domain, and apply to the same project, you can use one license.

Pro – Full plugin that can be used for 3 domains – price $109.

Developer – Full plugin that can be used on unlimited number of domains – price $249.

These prices are all based on a yearly subscription and all licenses include support and monthly updates the whole time subscription lasts, unlimited tables, unlimited charts, conditional formatting and separate database support.

If you cancel subscription after one year, plugin will still work properly and you will have all your settings. You will not have new updates and customer support.
