The short answer is Yes!
You can sell your products on any other marketplace, website or store you wish. We never will claim exclusivity over your files. It is important to us that your business is as successful as possible. Limiting this via exclusivity does not fit with our mission to be successful together.
Part of that success is making our marketplace the best fit for you and your products. If there's something we are missing do not hestitate to get in touch with us.
