Create my own website with Singe-use license template

Design help General

Hi everyone,
I’m consider to buy a template with single-use license, but i have few questions here.

  1. I already have a web domain and web hosting, can i publish my edited version (edited at Webflow) to my website without need to charge any addition fee for this template?
  2. When i want to add more backend features, such as connecting to a database and so on, i need to export my edited version to HTML/CSS/Javascript code to continue to coding, and update future versions to my website above, so Will I have any issue in my single-use license here?
    Thanks for you help.
