Hello!
Sorry, I write through the translator!
The question is under license "Starter". It is not clear.
1. I can download 3 templates and install them on 3 domain?
For example:
"Bistro" - 1 website
"hi-fi" - 1 website
"Bike" - 1 website

2. Or each template separately, I can put on 3 domain?
For example:
"Bistro" - 3 website
"hi-fi" - 3 website
"Bike" - 3 website

This is the right one:

"Bistro" - 1 website
"hi-fi" - 1 website
"Bike" - 1 website

But you can download "all" template and test them on local Server.

Thanks for the reply! Can I remove your Copyright with free templates?
