No Refunds After Download
Please note that due to the nature of digital goods, we cannot offer refunds once a product has been downloaded. This is because digital products, such as plugins, maps, and other tools, can be duplicated and used without any means to return the original item. Therefore, all sales are considered final once a download has been completed.
