Hey Gordon,
We are currently working on the WordPress versions of our designs.
We will launch the WordPress themes in less than 2 months.
Now, to answer your question - you can use all our particles to build similar (or even the same) designs for your clients. But you cannot distribute the WP theme as your own product and sell it as such.
Here's what I mean - there is a big difference between developing the website for the end user (your client) and selling the theme as a product.
When you develop the website for the end user, the product is the
website and their is just one client.
While, if you sell the WP theme on your website or on a marketplace, then the product is the
theme and there might be many people who will purchase it, therefore there might be many clients.
In short, you can use all our products to build the
website for the end user. But you cannot re-distribute our products and sell them as yours.
I hope that I answered your question
