Draft status and covered versions
Revision 0.1 · Draft, not yet effective. These terms apply only when an authorized licensor supplies a final agreement with a specified SDK or source order. Display on this website does not change existing licenses. The current local repository and SDK still include MIT texts; package licenses, ownership and third-party notices must be reconciled before a release under the new terms.
1. Licensor and covered materials
The licensor is the rights holder identified in the accompanying package license notice and authorized to license the materials. The licensee is the person or organization using or distributing them. This agreement covers official precompiled runtimes, import libraries, static libraries and tools, plus integration headers, bindings, wrappers, examples and documentation designated in that release manifest. Engine implementation source is excluded. Section 5 governs third-party components.
2. Free use and redistribution
The licensor grants worldwide, non-exclusive, royalty-free rights to use, copy and integrate the covered materials in personal, internal and commercial projects; redistribute official precompiled materials as a standalone SDK, mirror, installer or part of an application; and supply products containing them free of charge or for payment. Official static libraries may be linked into applications, and official dynamic libraries may be shipped with applications. No license fee is based on seats, installations or application revenue, and application source disclosure is not required. Rights to a covered version remain valid while these terms are met, even if later versions use different terms.
3. Integration code and your application
Integration headers, bindings, wrappers and examples designated in section 1 may be modified for integration, adaptation and application development, and their original or modified source and compiled outputs may be distributed with the relevant license notices. Independently written HTML, CSS, Lua, application code and extensions remain owned by their rights holders. Calling KUI APIs alone does not subject that code to the engine source agreement. This provision does not reclassify engine implementation source, copied portions of it or its compiled outputs as freely redistributable integration code.
4. Notices on redistribution
Redistribution must include this agreement, applicable copyright notices and third-party licenses and notices. For static linking, these may be included in the application’s accompanying license files. Installation paths, compression and application packaging may change; modified or independently compiled engines must not be presented as official precompiled releases. Covered materials remain under this agreement downstream. Separate terms may govern the licensee’s application, without removing recipients’ existing rights to the covered materials.
5. Third-party components
Third-party components remain licensed under their own terms, which control those components. The licensee must meet applicable attribution, license-text, source-offer, relinking or other requirements for the components actually redistributed. This agreement neither restricts rights granted by those licenses nor waives their obligations. Use the notices for the particular release; components, build options and platforms may differ.
6. Reserved rights
Intellectual property in the covered materials remains with the respective rights holders. This agreement grants no right to obtain, modify or distribute engine implementation source, or to claim endorsement under the KUI brand. Engine source and materials compiled from that source require the separate commercial source agreement. The free redistribution grant for official precompiled packages remains separate from restrictions on purchased source.
7. Warranty and liability
To the extent permitted by applicable law, the materials are provided as is, without warranties of merchantability, fitness for a particular purpose, non-infringement, continued availability or freedom from defects. To the extent permitted by law, the licensor is not liable for indirect losses, lost profits or lost data arising from use or inability to use the materials. Liability that cannot legally be excluded is not excluded. Separately signed paid service or warranty commitments follow their written terms.
8. Breach and applicable text
The licensor may terminate the licensee’s grant for a material breach not remedied within a reasonable period after notice. Termination does not retroactively revoke independently acquired rights of compliant downstream recipients. Unauthorized use and distribution must cease and noncompliant copies must be addressed, without affecting records lawfully retained. The final package agreement must identify the licensor, covered versions, contact channel and dispute arrangements. This website draft does not select those unresolved items. The final accompanying document must specify the interpretation priority of the language versions.
