Before asking for a refund regarding a technical issue or any other problem, please open an inquiry as early as you can and let us know what the issue is. We would like to meet the needs of you or your students. Detailed feedback can help me optimize these tools to improve them.

Ideally, individual users will discover any issues within 24 hours. Groups and classes might take three days. Depending on the specific issues we can discuss how best to solve problems.

If for some reason we cannot make these tools serve the needs of you or your group, we will process a refund.
