Do I need a second license for my local development ?


I am not sure if this is the right place to post this, but I have a question as a potential customer of a specific Joomla-Template on I can imagine that this topic is discussed a hundred times before my post, but I can’t find the answer in this forum, in the license descriptions or in the FAQ area.
I am planning to develop my website locally (for example with Xampp) and when I finished with that, I would move all of it to a real webserver and delete the local content. At no time I have two installations of the proposed template running ?
How many licenses do I need for this approach ? Do I need two or is one license enough ?

Thank you for your time.

For localhost, you don’t need any other license
