Hi there, @Arctico !
Welcome to the Community! Definitely a great place to gather some input regarding anything about the platform!
Are you able to tell us more about your business model? The more information we get, the better understanding we have of your situation. However, based on what you described in the intial thread, which is a typical dropshipping model, products you source from said apps/suppliers are legally allowed to be sold.
For information about dropshiping, give these resources a look over as they provide all the essential information when it comes to this business model:

Definitely looking forward to hearing from you.
