Terms of service

Plain-English terms for BigBrain product subscriptions (godspeed, ash, alice, conjure, boltzmann), operated by BigBrain LLC.

The deal

• BigBrain products are licensed, not sold: one monthly subscription covering the products you chose (see pricing). Founders keep their price for as long as their subscription stays active; each product’s price doubles for new subscribers at its 1.0.
• One subscription = one person. Install your products on the machines you personally use — a license key works on any supported OS and moves between your computers freely.
• Everything you make with our products is yours — no claim on your work, no telemetry of it. That is unconditional and it does not expire with your subscription. Artwork you create in godspeed is yours outright: meshes, textures, materials, scenes and anything else you author stay yours to use, sell and license anywhere, forever, whether you subscribe or not. We claim nothing on them, ever.
• The one thing that is not free forever is running our runtime, which is a separate matter from what you made with it — see the runtime below. While you subscribe, it costs nothing.

The keys

• Each product in your subscription has its own license key. Your keys are yours; do not publish or resell them. A key that leaks into public circulation may be revoked (we will re-issue to the legitimate owner).
• Changing your product mix is a plan switch in the Stripe billing portal; keys for added products arrive by email, keys for removed products deactivate at the switch.
• Cancel any time from the Stripe billing portal link in your receipt emails; your products keep working until the paid period ends, plus a short grace window.

The runtime

• Every BigBrain product runs on the godspeed runtime, which is included with every subscription and is not sold separately.
• You owe nothing until a product earns $1,000,000. Below that, ship what you build on the runtime, sell it, charge whatever you like: no royalty, no revenue share, and no reporting obligation of any kind. You will not hear from us.
• Once a product passes $1,000,000 in lifetime gross revenue, it carries 1% of the gross above that first million — gross meaning what your users pay you, before your own costs, platform fees and taxes. The threshold is measured per product, across its whole commercial life. The first $1,000,000 is never charged.
• The royalty attaches to shipping on the runtime, not to whether you are still subscribed. Your subscription buys runtime updates and the right to produce new builds; the 1% is the price of distributing on the runtime, and it applies either way.
• Artwork is exempt. The 1% attaches to running our runtime, never to what you made with our tools. Selling meshes, textures, materials or scenes you authored in godspeed carries nothing, ever.
• Non-profits and federally funded government research are exempt entirely.
• Reporting and payment, once a product is past the threshold: quarterly, on the calendar quarter ends. Each quarter’s 1% is due before the following quarter date, which gives you three months to pay it.
• Why this exists: people build on the runtime and then depend on it for years. Keeping it working — ported, patched and secure — costs us something whether or not the people relying on it are still subscribers, and the 1% above a million is that cost. For comparison, Unreal Engine charges 5% at the same $1,000,000 threshold.

The fine print

• The software is provided as-is, without warranty; our total liability is capped at the fees you paid in the last 12 months.
• Payments are processed by Stripe; we never see or store your card number.
• These terms may evolve with the product; material changes are announced by email.
