Janus Engine License

“Janus Technology” means Janus Engine as we make it available to you, including:

• Engine Code: the runtime, editor and tools, in object code and, where we provide it, source code, plus any future versions we provide under this License;
• SDKs and integrations: libraries, plug-ins, templates and command-line tools for building with Janus;
• Samples and Starter Content: example projects, code, art, audio and other content we bundle with the engine; and
• Documentation: guides and references for the above.

Any modified version of the Janus Technology that you make is also Janus Technology.

This License does not cover Janus Studio’s web tools, the Janus API or credits (see the Janus Studio & Credits Terms), our games or their content, or third-party components that come with their own licenses (see Section 7).

Subject to this License, IDFire grants you a worldwide, non-exclusive license, which you may not transfer or sublicense, to install, run, copy, modify, display and perform the Janus Technology so that you can develop, test, market and distribute games, interactive experiences, applications, linear media and other products made with it (each a “Product”), and to distribute Products as described in Section 4.

You may let your employees and contractors use the Janus Technology to work on your Products, as long as each of them has accepted this License and you remain responsible for what they do.

Janus Engine is free to download and use. You owe nothing to develop, prototype, learn or make non-commercial projects.

When you distribute a Product that earns money (a “Royalty Product”), you pay IDFire a royalty of 5% of Gross Revenue for that Product, but only on Gross Revenue above the first US$1,000,000 earned by that Product over its lifetime. The royalty rules are in the Royalty Terms in Section 5.

Royalties are separate from Janus Studio credits. If your Product calls Janus cloud services (for example, AI features that run on our servers), those services are billed separately at the prices we publish for them.

You may distribute Products to anyone, on any platform or store, under your own brand, as long as:

• the Janus Technology is included only in object code (or as compiled or packaged data) and only as an inseparable part of your Product;
• your Product does not let end users extract, reuse or modify the Janus Technology except through editors, mod tools or scripting you deliberately expose as part of the Product;
• your end-user terms are at least as protective of the Janus Technology as this License, and do not make any promises on our behalf; and
• you pay any royalties due under Section 5.

Royalty-free distribution

No royalty is due for Products that do not earn revenue, for videos, screenshots, trailers and other media that don’t contain Engine Code, for internal tools and prototypes used only within your organization, or for Products you build for a client under a work-for-hire arrangement where the client distributes them (in that case, the client owes any royalty on its own Gross Revenue).

Sharing the engine itself

You may share Engine Code, including your modifications, only with other people who have accepted this License, and only through private channels (for example, a private repository). You may not publish Engine Code publicly or distribute the Janus Technology on its own, outside a Product.

Gross Revenue

“Gross Revenue” means all revenue attributable to a Royalty Product, from anywhere in the world, before deductions for store or platform fees, payment processing or publisher shares. It includes revenue from:

• sales and licenses of the Product, in any format and on any store or platform;
• in-app purchases, downloadable content, season passes, subscriptions and virtual currency used in the Product;
• in-Product advertising, sponsorships and affiliate programs;
• payments for including the Product in a subscription or streaming catalog; and
• advances, minimum guarantees and crowdfunding tied to access to the Product or benefits in it.

Gross Revenue does not include: the first US$1,000,000 of the Product’s lifetime Gross Revenue; sales and value-added taxes collected from customers; amounts actually refunded to customers or reversed by chargeback; revenue from physical merchandise and other non-software goods (such as soundtracks on vinyl, apparel or books); and donations that aren’t tied to access or in-Product benefits.

Reporting and payment

Before you first release a Royalty Product, tell us by emailing legal@radgames.ai with the Product’s name, platforms and expected release date. Once a Product’s lifetime Gross Revenue passes US$1,000,000, report its Gross Revenue and pay the royalty for each calendar quarter no later than 45 days after that quarter closes. Payments are made in US dollars, converted at a published exchange rate. Late payments may accrue interest at the lower of 1% per month and the maximum rate the law allows.

Taxes

You are responsible for taxes on payments you make to us, other than taxes on our own income. If the law requires you to withhold tax, you will gross up the payment so we receive the full royalty, unless a tax treaty reduces the withholding and you provide the required forms.

Records and audits

Keep accurate records of Gross Revenue for each Royalty Product for at least three years. Once per year, with at least 30 days’ notice, we may have an independent accountant review those records. If the review finds an underpayment of more than 5% for the period reviewed, you pay the shortfall and the reasonable cost of the review.

You may not, and may not allow anyone else to:

• rent, lease, sell or sublicense the Janus Technology, or offer it as a hosted service, except as part of a Product;
• use the Janus Technology, or content or data extracted from it, to train, fine-tune or evaluate an artificial-intelligence or machine-learning model, or to build a game engine or development tool that competes with Janus Engine;
• combine the Janus Technology with code under a license that would require the Janus Technology to be disclosed, licensed for free or distributed in source form (such as some copyleft licenses);
• remove or bypass license checks or other technical protection measures in the Janus Technology;
• remove or alter copyright, trademark or other notices in the Janus Technology;
• claim that the Janus Technology infringes a patent, or grant a security interest in it; or
• use the Janus Technology in violation of law, including export-control and sanctions laws, or to create Products that break the content rules in our Community Rules if you distribute them through our services.

You own your Products and everything you create in them, other than the Janus Technology itself. We own the Janus Technology and all intellectual-property rights in it. This License is a license, not a sale, and grants no rights except those stated.

Attribution

If your Product has credits, include the line “Made with Janus Engine. Janus Engine © IDFire Technologies Inc.” in them. You may say, factually, that your Product was made with Janus Engine. You may not otherwise use our names or logos, or suggest that we endorse your Product, without written permission.

Third-party software

The Janus Technology includes open-source and other third-party components. Their own license terms, listed in the third-party notices included with the engine, apply to those components, and nothing in this License limits your rights under those licenses.

Feedback and contributions

If you send us feedback, suggestions, bug fixes or code contributions for the Janus Technology, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use, modify and distribute them for any purpose, including in future versions of Janus Engine. You confirm that you have the right to grant that license.

Cloud features

When you use Janus features that run on our servers, you let us process the data you send solely to provide the feature to you. That processing is covered by our Privacy Policy and the Janus Studio & Credits Terms.

If the standard terms don’t fit your project (for example, you need a different royalty structure, a buy-out, source access, dedicated support, or terms for a large studio, a public institution or a platform holder), contact us at legal@radgames.ai. A signed custom license replaces this License to the extent it says so.

Changes

We may offer an updated License with new versions of Janus Engine. Updates apply only to versions released with them or later, and to services you access after accepting them; the License you accepted continues to govern versions you already have. We will tell you about material changes by email or in the engine or on janusengine.com.

Eligibility

If you are under the age of majority where you live, you may accept this License only with the consent of a parent or guardian. You may not use the Janus Technology if you are subject to US sanctions or located in a comprehensively sanctioned country or region.

Termination

You may end this License at any time by stopping all use of the Janus Technology. We may end it if you materially breach it and don’t fix the breach within 30 days after we notify you (or immediately, for a breach that can’t be fixed, such as distributing Engine Code publicly). After termination, you must stop using and distributing the Janus Technology, but Products that were already distributed to end users can continue to be used by them. Royalties already owed remain payable.

Support

Under this License, we have no obligation to provide support, updates or bug fixes, though we often do. Support and service-level commitments are available under custom licenses.

To the fullest extent permitted by law, the Janus Technology is provided “as is” and “as available”, with all faults. IDFire and its affiliates, licensors and service providers disclaim all warranties, express or implied, including implied warranties of merchantability, non-infringement, title and fitness for a particular purpose, and any warranty that the Janus Technology will be error-free, secure or uninterrupted.

To the fullest extent permitted by law, IDFire will not be liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill, arising out of or relating to this License or the Janus Technology. IDFire’s total liability under this License will not exceed the greater of the royalties you paid us in the 12 months before the claim and US$1,000.

Nothing in this License limits liability that cannot be limited by law.

You will defend and compensate IDFire and its affiliates against third-party claims, and related losses and reasonable legal costs, arising from your Products, your modifications of the Janus Technology, or your breach of this License, except to the extent the claim is caused by the unmodified Janus Technology.

This License is governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. The UN Convention on Contracts for the International Sale of Goods does not apply. Any dispute will be heard only in the state or federal courts located in Delaware, and both parties consent to their jurisdiction. Either party may seek an injunction anywhere to protect its intellectual property.

To the extent the law allows, disputes under this License are brought only on an individual basis, not as a class or representative action.

• Export. The Janus Technology is subject to US export-control and sanctions laws. You will not export or provide it in violation of those laws.
• US government users. The Janus Technology is “commercial computer software” and is licensed to government users only under this License.
• Assignment. You may not assign this License without our written consent, except to a buyer of all or substantially all of the business that develops the relevant Product, who must accept this License in writing. We may assign it to an affiliate or successor.
• Relationship. We are independent contractors. This License does not create a partnership, joint venture or agency.
• Entire agreement; severability; no waiver. This License, and any documents it references, is the whole agreement about the Janus Technology. If a provision is unenforceable, the rest remains in effect. Not enforcing a provision is not a waiver.
• Survival. Sections on royalties, ownership, disclaimers, liability, indemnity and governing law survive termination.
• Language. English is the controlling language of this License.
