Pre-sales question

If you read the whole page, it also says:

The table above says “Pay once, use forever”, but the prices are listed per year. The price is indeed a yearly subscription, but if you don’t renew the subscription, the plugin will not stop working. You just won’t get new updates. You get a working plugin and by paying just once, you can keep on using the version you have as long as you want to. In order to get support and upgrades, you need to have an active subscription.
