Refunds and cancellations

Each product page on this website clearly displays links to samples for detailed functionality verification of the product, or to a complete set of documentation necessary for building and extending the product within your own Gemini (GEM) or Notebook environment. We have established a system that allows you to download and review these materials in advance. Please thoroughly check the product's functionality, effectiveness, and compatibility with your environment using the documentation and samples beforehand, and only submit your purchase application after you are completely satisfied with the content. Due to the nature of digital products and environment setup documentation, and because we assume that you will be fully satisfied with the samples and documentation provided beforehand, we cannot accept cancellations or refunds after payment has been completed. Please ensure you thoroughly verify the functionality beforehand.
