Welcome to Bubble, I had this question a good while a go when I first started on Bubble I messaged the legal team and this is the response I got, hopefully it will provide some clarification.
Thanks for reaching out! In accordance with our terms, specifically, Sections 6h and 2b, you may not “rent, lease, share, distribute, or sell [the template you purchased] to any third party…”
I hereby give you permission to modify and configure my templates as your own prototype outside of Bubble
This means you can’t re-sell the same template on the Bubble marketplace, outside of this scope I don’t mind whatever you’re planning to do. You can check my templates below.
There are points I don’t like as a template user. First of all, I think the option should be given for commercial purposes. In addition, it may be 20-30% more expensive and / or not allowed to reuse.
