1. Purpose and structure of this page
This page sets out the licences under which QODIQA RESEARCH AND DEVELOPMENT S.R.L., Bucharest, Romania (the ‘Company’, ‘we’, ‘us’ or ‘our’) makes the qodiqa software, the qodiqa specification and the content of the website qodiqa.com (the ‘Website’) available, and the rules for the use of the qodiqa name, logo and other marks. Open-source licences cover the software and the specification. They do not cover the Company’s names, logos and marks, or the Website’s own content and design, which are reserved to the Company except as stated below.
2. Order of precedence and interpretation
This page is a summary and policy statement. The full text of each licence, as published in the relevant repository and at the licence’s official source, governs the material it covers and prevails over this page in case of conflict. The Terms of use of the Website apply to the use of the Website and refer to this page. Where this page and a licence differ, the licence controls for the material it covers, and this page controls for the Company’s names, logos and marks.

4. Open-source software
The qodiqa software published in the Company’s public repositories is licensed under the Apache License, Version 2.0, unless a repository states otherwise. Under that licence any person may use, reproduce, modify and distribute the software, in source or binary form and including for commercial purposes, provided that the person includes a copy of the licence and the applicable notices, states significant changes made to modified files, and retains the attribution notices. The licence includes a grant of patent rights from each contributor for their contributions, which terminates for a person who brings patent litigation alleging that the software infringes a patent. The software is provided ‘as is’, without warranty of any kind, as set out in the licence. The licence does not grant any right to use the Company’s names, logos or marks except as required to describe the origin of the software and to reproduce the notice content.
5. Specification
The qodiqa specification corpus is licensed under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). Any person may share and adapt the material for any purpose, including commercially, provided that the person gives appropriate credit, provides a link to the licence, indicates whether changes were made, and does not suggest that the Company endorses the person or the use. A suitable attribution reads:
‘Based on the qodiqa specification, QODIQA RESEARCH AND DEVELOPMENT S.R.L., licensed under CC BY 4.0, https://qodiqa.com. Changes made: a description of the changes, or the statement that no changes were made.’
An adaptation of the specification is not the qodiqa specification, and must not be presented as an official version. The corpus document titled Public Specification License is kept in the corpus as a historical record and is superseded by CC BY 4.0, as stated in the corpus repository.
6. Test vectors, examples and documentation
Test vectors, examples and documentation are licensed as stated in the repository in which they are published. Where a repository states no separate licence for such material, the licence of that repository applies. Test vectors are published so that independent implementations can check themselves against the same results; reuse of them within the terms of their licence is encouraged.
7. Website content and design
Except for material published under an open-source or Creative Commons licence, the content of the Website, including its text, diagrams, graphics, layout and visual design, is the property of the Company or its licensors, and all rights are reserved. A visitor may view the Website, link to it and quote short excerpts with attribution and a link to the source. Reproduction of the Website as a whole, or of its design, diagrams or graphics, requires the Company’s prior written permission.
8. The qodiqa name, logo and marks
The name ‘qodiqa’, the qodiqa logo and the Company’s other names, logos, wordmarks and distinctive signs (together the ‘Marks’) are the property of the Company, whether or not registered. The open-source licences and the Creative Commons licence described above do not grant any right in the Marks. In particular, section 6 of the Apache License 2.0 does not permit use of the Company’s trade names, trademarks, service marks or product names, except as required for reasonable and customary use in describing the origin of the work and in reproducing the content of the notice file.
9. Uses that do not require permission
The following uses do not require the Company’s permission, provided that they are accurate and do not suggest endorsement, sponsorship, certification or affiliation: (a) referring to the project, the software or the specification by name in text, including in articles, academic papers, documentation, presentations and comparisons; (b) stating that a product or service is built with, integrates with, or implements the qodiqa software or specification, where that is true; (c) linking to the Website and to the Company’s public repositories; (d) distributing unmodified copies of the software under its licence, using the name only as it appears in the licence and the notices; and (e) reproducing the logo in unmodified form in editorial, academic or news contexts that report on the project.
10. Uses that require written permission or are not permitted
Without the Company’s prior written permission, no person may: (a) use the Marks, or a confusingly similar sign, as or within the name of a company, product, service, package, repository, application, domain name or social media account; (b) use the logo in a product, on packaging or in marketing, or alter, animate or recombine the logo; (c) state or imply that the Company has certified, approved, audited, endorsed or sponsored a person, product, service or conformance claim; (d) distribute a modified version of the software under the name ‘qodiqa’ or under a name that is likely to be confused with it, and modified versions must be clearly identified as such and carry a distinct name; or (e) register or apply to register the Marks, or confusingly similar signs, as trademarks, domain names or business names. Requests for permission may be sent to legal@qodiqa.com.
11. Statements about conformance
There is no certification body for the qodiqa specification, and the Company does not issue certificates, seals or attestations of conformance. A person who wishes to publish a statement about conformance with the specification may do so only if it is accurate, describes itself as a self-assessment, identifies the specification version and the profile assessed, gives the date of the assessment and links to the specification. Terms such as ‘certified’, ‘approved’ or ‘endorsed by qodiqa’ must not be used. The Company may ask for the correction or removal of a statement that does not meet these conditions.
12. Contributions
Unless a repository states otherwise, a contribution that a person intentionally submits to a public repository is licensed under the licence of that repository, as provided in section 5 of the Apache License 2.0 for the software repositories. The repositories do not require a contributor licence agreement or a Developer Certificate of Origin sign-off. Contributors retain the copyright in their contributions and confirm that they have the right to submit them. A contributor who has not obtained any necessary permission from an employer or other rights holder should not submit the contribution.
13. Third-party components, names and assets
The software and the Website use or reference third-party components and assets, including libraries, fonts, icons and the names and logos of AI providers, standards bodies and regulatory frameworks. Each is subject to its own licence or terms, which are indicated in the relevant repository, in the dependency licence information or on the owner’s site. Third-party names, logos and marks belong to their respective owners, appear for identification only and do not indicate affiliation with or endorsement by them or by the Company.
The Website self-hosts the Geist, Geist Mono and Inter typefaces under the SIL Open Font License 1.1, and bundles the @noble/curves and @noble/hashes libraries under the MIT licence; the licence texts ship with the files. Its brand icons are single-path glyphs from the Simple Icons set, which is dedicated to the public domain under CC0 1.0, and the framework logos and the flag of Europe are used only to identify the framework concerned; a public-domain or CC0 dedication of artwork does not grant any right in the underlying trademark. The integration strip and the Integrations page show the marks of Kubernetes, Helm, Prometheus and OpenTelemetry, taken unaltered from the Simple Icons set (the icon files are CC0 1.0; the marks remain the property of their owners) and used only to identify the technology, and identify every other integration by a monochrome glyph, a generic icon or, on the Integrations page, a first-letter monogram; the sources and the brand guidelines consulted are recorded in the file assets/logos/RIGHTS.md of the Website source. The Website’s third-party notices file records each component, its version and its licence. The qodiqa-gateway distribution includes third-party components under their own licences, including an Apache-2.0 base embedding model and, loaded dynamically, libvips under LGPL-3.0, as listed in its NOTICE file.
14. Reservation of rights; no implied licence
All rights that are not expressly granted by the licences described in this page are reserved by the Company and its licensors. No licence or right is granted by implication, estoppel or otherwise, and the grant of a licence for one item does not extend to any other item.
15. Reporting misuse and infringement
Suspected misuse of the Marks, misleading conformance statements, or infringement of the Company’s rights may be reported to legal@qodiqa.com. The Company may take the steps that the law and the applicable licences allow, including requesting correction or removal, without prejudice to any other right or remedy.
16. Changes to this page
The Company may update this page from time to time. The version and effective date shown at the top identify the current version. Updates do not retroactively alter the terms of a licence that the Company has already granted for a published release of the software or the specification.
17. Governing law
This page and the use of the Marks are governed by Romanian law, and disputes are subject to the jurisdiction stated in the Terms of use, without prejudice to the governing-law provisions of the licences themselves and to any mandatory rights.
