Papa's Rocket CampTerms of Use

Terms of Use

Last updated 22 August 2026

This site and the flight simulator on it were built by one person for kids and the grown-ups flying with them. These terms say what you may do with it, and what it does not promise. Plain language, on purpose.

1. Copyright

Everything here — the simulator, its flight model, the site, the writing, the artwork, and the badge — is original work and is protected by copyright. The "Papa's Rocket Camp" name and badge are used as marks of this project.

Rocket kit names, engine designations, and manufacturer data referenced in the simulator belong to their respective owners. They appear here to describe real products, and this project is not affiliated with, endorsed by, or sponsored by any of them.

2. What you may do

Use the simulator, free, as much as you like.
Use it at home, in a classroom, at a club, or at a launch.
Link to it, show it to people, put it on a screen at an event.
Print or screenshot your own flight results for your own use.

3. What you may not do

Copy, host, or republish the simulator or the site, in whole or in part, anywhere else.
Sell it, bundle it into a product, or charge anyone for access to it.
Take it apart to reuse its flight model, data, or code in another project.
Remove or alter copyright notices.
Present it as your own work, or use the name or badge in a way that suggests you built it or that it endorses you.

Any of those needs written permission from the owner first.

4. The simulator is a simulator

A simulated flight is not a real flight. Nothing here replaces a careful adult, the manufacturer's instructions, or the NAR Model Rocket Safety Code.

The flight model uses published engine data and real physics, and it works hard to be accurate. It is still a model. Real rockets meet real wind, damp field grass, a fin glued slightly crooked, and a hundred other things no simulation captures. Numbers it gives you are estimates for learning and planning, not guarantees.

You are responsible for your own launches: your equipment, your field, your weather, your local rules, and the people standing nearby. Fly under the safety code, follow the kit and engine instructions, and use your own judgment.

A green light in the simulator is not a safety inspection, a certification, or a permission slip. It means the numbers looked reasonable to a computer program. It says nothing about the rocket sitting on your pad, how it was built, or whether today is a good day to fly it.

5. You fly at your own risk

Model rocketry carries real risk. Engines misfire. Parachutes fail to open and rockets come in hard. Wind carries them onto roads, roofs, water, and other people's land. Rockets catch fire, break apart, and disappear into corn. None of that changes because a screen predicted something different.

By using this site or the simulator, you accept that every launch decision is yours alone, and you assume all risk of loss, damage, and injury arising from your launches and from anything you do with the information this site gives you — including a rocket you never get back.

6. No warranty

In plain words: this is a free program written by one person. It may be wrong. Treat every number as an estimate, never as a promise.

The site and the simulator are provided "as is" and "as available", without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement.

No altitude, speed, drift distance, descent rate, stability margin, recovery prediction, weather reading, or safety flag produced by the simulator is warranted to be correct, complete, or suitable for any decision you make about a real rocket.

7. Limits of liability

To the fullest extent permitted by law, Papa's Rocket Camp and its owner shall not be liable for any direct, indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of or damage to a rocket, engine, or equipment, loss of or damage to any other property, personal injury, or death, arising out of or relating to the use of, or inability to use, this site or the simulator — whether the claim arises in contract, warranty, tort (including negligence), strict liability, or any other theory, and even if advised of the possibility of such damage.

Because this software is provided free of charge, total liability for any claim shall not exceed zero US dollars ($0.00). A donation is a gift and does not change this.

Some places do not allow certain warranty exclusions or liability limits. Where that is true, the parts that are not allowed do not apply to you, and everything else here still stands.

8. Claims arising from your launches

If somebody brings a claim against Papa's Rocket Camp or its owner because of your rocket, your launch, or your use of this site — property damage, injury, a broken safety code, or a local ordinance — you agree to indemnify, defend, and hold them harmless, including reasonable legal costs.

9. Grown-ups are responsible for kids

This was built for a child and an adult to use together. Where a child uses the site or the simulator, the supervising adult accepts these terms on their behalf and stays responsible for what gets built, what gets flown, and who is standing nearby when it goes up.

10. Your data

There are no accounts and no sign-up. Flights you run are saved in your own browser's local storage on the device you used, and they never leave it. Clearing your browser data clears your flight log, and a log started on a tablet will not appear on a laptop.

When you look up live weather, the town you enter is sent to the Open-Meteo service to fetch a forecast. That request is subject to their terms and privacy policy, not this one.

The Donate tab uses PayPal's own donation button, which loads a script from PayPal and may set its own cookies. That part of the page is governed by PayPal's terms and privacy policy.

11. Donations

Donations are voluntary gifts toward running costs. They are not payment for goods or services, they buy no features, and they are not tax-deductible. Payments are handled entirely by PayPal under their terms — this site never sees or stores payment details.

12. Changes

These terms may change as the project changes. The date at the top says when they last did. Continuing to use the site means the current version applies.
