Sign-in asks GitHub only for your public profile and email address.
Questions
Before you buy
Can I try it before buying?
Yes, and you should. The whole game runs free in your browser at pinionfall.com, and the documentation is public. What you see there is what the source builds. Because everything can be evaluated first, purchases are final.
What exactly is licensed?
One legal entity (you, or your company including its employees and individual contractors) may use and modify the engine and ship an unlimited number of products built with it, commercial or not, with no royalty. The source itself may not be shared outside that entity, published or resold, in whole or in any part.
How is it delivered?
You sign in with GitHub, pay once, and your GitHub account is invited to the organisation’s four private repositories as a read-only collaborator as soon as the payment is confirmed. Accept the invitations on GitHub; an invitation can be resent from your account page.
Are updates included?
Yes. Each release is a snapshot commit on a linear history, so git pull works, plus a GitHub Release with the asset bundles. There is no subscription.
Is there a refund?
No refunds for a change of mind: delivery is immediate, you ask for it at checkout, and the product can be fully evaluated beforehand. If you never received access, write to us and we restore it; a duplicate purchase is refunded, and your statutory rights are not affected. A refund, chargeback or dispute ends the licence. See the refund policy.
What about the character animations?
They are included. Every clip was generated with Meshy (paid tier), from its action library or with text to motion, or derived from such a clip, then retargeted onto the engine’s own characters. Each records its source, the build checks it, and the clips ship under the licence. No third-party account or extra setup step is needed.
Which machines run it?
A browser with WebGPU. The engine is developed in Chrome and Edge on Windows; iOS and iPadOS Safari run a reduced-memory path; other WebGPU browsers are not tested. A discrete GPU is strongly recommended for development.
Who handles payment and tax?
Checkout is run by Stripe, whose Link service acts as the merchant of record: it charges the price shown, handles VAT and sales tax, and issues your receipt.
Where is Pinionfall sold?
Currently only to customers located in the countries and territories where the merchant of record collects and remits VAT, GST or sales tax on the sale: the United States, Canada, the United Kingdom, Switzerland, every EU member state and 50 more. The full list is in the country menu at checkout and in section 4.5 of the terms of sale. If your country is missing, the licence is not available there yet. A purchase whose billing address is outside the list is declined and refunded in full automatically.
Can the licence move to another company?
Yes. The whole licence can be transferred to one other person or company, for example when a business is sold. Write to support@pinionfall.com naming the new holder, with their acceptance of the licence; the transfer takes effect when we confirm it, and access moves to their GitHub account.
