Welcome to the iMatonia Refund Rules. Because we are a platform, these rules outline what you can expect from the authors of the items you buy. They apply to all authors and customers.
The products that authors sell on the platform are digital goods and cannot be "returned", so your entitlement to a refund is designed with this in mind. Of course, in addition to these rules, each country has its own laws surrounding refunds, and these local laws are not excluded if they apply to you.
