Terms of use
Last updated: November 6, 2026
By using projectmoonpi.com you agree to these terms. They're written to be read.
The site
Project Moon Pi makes hobby hardware, software and games. The information on this site is provided for general interest. Projects marked "coming soon" or "in development" are not finished, and their details may change before they're released.
Free downloads
Free software offered here is provided under the licence included with it (for open-source projects, usually the MIT licence). Unless that licence says otherwise, it is provided "as is", without warranty of any kind. You use it at your own risk.
Hardware designs and projects
Hardware described on this site, including boards, wiring and installation guides, involves electrical systems and machinery. Hardware marked "in development" has not been field-tested. Anyone building or installing it is responsible for doing so safely, for checking it suits their equipment, and for following the equipment maker's instructions and local rules. Project Moon Pi is not responsible for damage to equipment or injury resulting from building, installing or using it.
Games
Aviator Trail is a game, made for entertainment, and a work of fiction and parody. It is not flight training and does not take the place of real training. Nothing in it is career, financial, legal, medical or flight-training advice, and it gives no training credit. For real decisions, use official sources: the FAA, 14 CFR, your aviation medical examiner, your instructor and the employers themselves.
Paid products
Paid products are sold by Lemon Squeezy, our authorised reseller and merchant of record, under its terms of sale, shown at checkout. Each purchase gives you a licence to use the product on up to the number of computers stated for it; the licence key is for you, not for sharing or resale. Our refund policy applies.
Content and names
The site's text, images, logos and the Project Moon Pi badge belong to Project Moon Pi unless stated otherwise. Please don't copy them for commercial use without asking. Other names are covered on the trademarks page.
Limitation of liability
To the fullest extent the law allows, Project Moon Pi is not liable for any indirect, incidental or consequential loss arising from use of this site or anything downloaded from it.
Governing law
These terms are governed by the laws of the State of Arizona and applicable United States federal law, without regard to conflict-of-law rules. Nothing here limits any consumer rights you have under the law where you live.
Changes
We may update these terms; the current version is always on this page. Questions: support at projectmoonpi dot com.
