Terms of service
Last updated November 15, 2026
These terms are an agreement between you and MD Space LLC, which runs MD Space STEM. By creating an account or buying a program, you agree to them.
Who can use the site
Accounts are created by parents and legal guardians aged 18 or older. A parent can add accounts for their own children aged 9 to 14, who then sign in with a username. You are responsible for your account, your children’s accounts, and keeping their passwords private.
Programs and access
- A program is bought once, for one child. The price is shown before you pay and includes every lesson, the quizzes, an instructor’s review of the final project, and a certificate when the program is completed.
- Lessons open in order. After a child finishes a program, they can keep watching its lessons for 90 days.
- Packages marked “coming soon” cannot be bought yet. We may change prices for future purchases; a price you already paid does not change.
Payment and refunds
Payments are processed by Stripe. All sales are final, as explained in our refund policy.
Final projects and certificates
Your child keeps ownership of the work they hand in. You allow us to store it, show it to our instructors and to you, and keep it with your child’s account. We do not publish it. A certificate is issued after an instructor approves the final project. We may withdraw a certificate that was earned with work that is not the child’s own, and anyone checking its ID will then see that it was withdrawn.
Building projects at home
Some lessons ask children to build things with everyday materials, such as balloons, string and eggs. Please supervise these activities. Follow the safety notes in each lesson, and do not let children use tools or materials that are unsafe for their age.
Using the site fairly
- Do not share an account or let more than one child use a child’s account.
- Do not copy, download, record or share the lessons, games or materials outside your family.
- Do not upload anything unlawful, harmful or that belongs to someone else.
- Do not try to get around payment, open locked lessons, or break the site.
We may suspend an account that breaks these rules. If we close an account for a reason other than a breach of these terms, we will tell you why.
Our content
The lessons, games, narration, figures and design belong to MD Space LLC. Some films use footage from NASA, which is in the public domain; NASA does not endorse this program.
Availability and changes
We work to keep the site available, but it may sometimes be down for maintenance or problems outside our control. We may improve or change lessons over time. If we change these terms, we will update the date at the top; continuing to use the site after that means you accept the change.
Disclaimers and limits
The site is provided “as is”. To the extent the law allows, we are not responsible for indirect or unexpected losses, and our total responsibility to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits rights you have that the law does not allow us to limit.
Law
These terms are governed by the laws of the State of Texas, United States. Before starting any legal claim, please write to us so we can try to resolve it.
