Some questions about Kodular Premium

Hi, I’m about to purchase kodular premium, but before I do I have some questions:

  1. Is it possible to get a refund if something goes wrong?
  2. I’m planning to use monetization extensions. What is going to happen to them if my membership expires? Will they still work in my published apps?
  3. Is the membership going to renew automatically every month/year?

Yes it will be working in publish apps you need to again subscription if you want to update your app
