Lets3dPrintTerms of Use
Last updated: 6 October 2026
Licence
Lets3dPrint is licensed to you under Apple's Licensed Application End User License Agreement (the standard App Store EULA). These terms add details about subscriptions and the open-source software inside the app.
Lets3dPrint Pro
- Monthly ($0.99 per month) and Yearly ($6.99 per year) are auto-renewing subscriptions. Prices are shown in your local currency in the App Store before you buy.
- Each subscription starts with a one-week free trial if you have not used one before. If you do not cancel during the trial, the first payment is charged when it ends.
- Payment is charged to your Apple Account when you confirm the purchase (or when the trial ends). Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; the renewal is charged within 24 hours before that.
- You can manage or cancel a subscription in your App Store account settings. Cancelling stops the next renewal; Pro stays active until the end of the paid period.
- Refunds are handled by Apple at reportaproblem.apple.com.
- Modelling, saving and opening projects are free and do not require Pro.
Your designs
You own everything you design in Lets3dPrint. We claim no rights to your projects or exported files.
No warranty for printed parts
Lets3dPrint is a design tool. Check dimensions, tolerances and strength before you rely on a printed part, especially for anything load-bearing or safety-related.
Open-source software
Lets3dPrint's geometry kernel is our own code. It uses two small open-source libraries, compiled into the app:
- Manifold 3.5.4, © the Manifold authors, licensed under the Apache License 2.0.
- Clipper2 1.5.4, © Angus Johnson, licensed under the Boost Software License 1.0.
Their full licence texts are included in the app (Acknowledgements.txt in the app bundle).
