Website terms and brand policy.

Last updated April 19, 2026.

These terms govern your use of the CLUB project's public website and set out how the CLUB name and logo may and may not be used. They do not replace the Apache License 2.0, which governs the software itself, and they do not apply to self-hosted CLUB instances — each operator of a CLUB instance publishes its own terms for its users.

1. About these terms

"CLUB," "the project," "we," and "us" refer to the maintainers and contributors of the open-source CLUB software. "You" refers to a visitor to this website or anyone using the CLUB name, logo, or other brand assets. By using the website, you agree to these terms. If you do not agree, please do not use the site.

2. The software is governed by Apache License 2.0

The CLUB source code is released under the Apache License, Version 2.0. The license is the authoritative statement of your rights in the code — including the copyright and patent grants, the requirement to preserve notices in derivative works, and the disclaimers of warranty and liability. Nothing on this website expands, restricts, or replaces that license.

A copy of the license is distributed with the source at LICENSE and at apache.org/licenses/LICENSE-2.0. If there is any conflict between these website terms and the Apache License 2.0 regarding your rights in the code, the Apache License controls.

3. Website use

The content of this website — copy, images, and layout (but not the CLUB word mark or logo, covered separately in section 5) — is made available so you can learn about, evaluate, and operate the CLUB software. You may link to this site, quote short excerpts for commentary or review with attribution, and share permalinks freely.

You agree not to:

  • scrape, probe, or load-test the website in a way that degrades it for other visitors;
  • attempt to access non-public areas, bypass access controls, or exploit vulnerabilities (responsible disclosure through the project's public repository is welcome);
  • misrepresent the origin of website content, or pass off modified copies as if they came from the CLUB project;
  • use the website, or content downloaded from it, to build a competing service that implies an affiliation with or endorsement by the CLUB project when none exists.

4. Third-party services and links

Some pages link to or rely on third-party services — the project's GitHub repository, the documentation host, and the package registries and language sites the software interoperates with. Those services are operated by others under their own terms, and the CLUB project is not responsible for their content, availability, or practices.

5. Trademark and brand policy

The Apache License 2.0 grants copyright and patent rights to the software but — in section 6 of that license — does not grant permission to use the trade names, trademarks, service marks, or product names of the licensor, except as required for describing the origin of the work and reproducing the NOTICE file. The policy below explains what the CLUB project does and does not permit under that reservation.

5.1 What is reserved

The name "CLUB" used as the name of this software project, the associated word mark, the CLUB logo and full-logo lockup, and confusingly similar variants are trademarks of the CLUB project maintainers. These marks are reserved even in jurisdictions where formal registration has not been obtained. They serve to identify authentic releases of the software and the project's own communications.

5.2 What you may do without asking

  • Refer to the project by name. You may use the word "CLUB" in factual, descriptive statements — for example, "built on CLUB," "compatible with CLUB," "we run a CLUB instance," or in blog posts, talks, and articles that discuss the software.
  • Distribute unmodified binaries and source. You may redistribute the software under the Apache License 2.0 while keeping the project's name, logo, and in-product branding intact, because that is how users identify the authentic release.
  • Link to us. You may link to this website and to the project's repositories, and use the CLUB word mark as link text.

5.3 What requires prior written permission

  • Using "CLUB" (alone or as a prefix or suffix) in the name of a product, service, company, domain, app, or package — especially in a way that suggests the offering is the official CLUB project, is endorsed by it, or is its commercial edition.
  • Using the CLUB logo or full-logo lockup on merchandise, event branding, or marketing for a paid service.
  • Distributing a modified fork of the software under the CLUB name. You are free to fork under the Apache License, but a materially modified build must ship under a different name and logo so that users are not misled about what they are running.

Permission requests can be filed as an issue in the project's public repository at GitHub.

5.4 Brand usage rules

  • Always spell the name as CLUB in marketing contexts. Do not alter the letterforms, recolor, distort, or re-tint the logo, and do not combine it with other marks in a way that implies a joint venture.
  • Do not use the CLUB name or logo as a favicon, app icon, or default avatar for a non-CLUB product.
  • When describing your own offering, make the relationship to the project accurate: for example, "hosted CLUB by ExampleCo" is fine if you actually host unmodified CLUB; "CLUB Pro by ExampleCo" is not, because it implies an official edition.

6. Contributions

Contributions to the project — code, documentation, issues, or comments — submitted through its public repositories are contributed under the terms of the Apache License 2.0 as described in section 5 of that license, unless the contributor clearly marks the submission otherwise.

7. No warranty; limitation of liability

This website and the CLUB software are provided "as is," without warranty of any kind, express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, non-infringement, or uninterrupted availability. To the maximum extent permitted by applicable law, in no event will the CLUB project, its maintainers, or its contributors be liable for any direct, indirect, incidental, special, consequential, or punitive damages — including lost profits, lost data, or business interruption — arising out of or in connection with your use of this website or the software, even if advised of the possibility of such damages. Sections 7 and 8 of the Apache License 2.0 apply in full.

8. Changes

These terms may evolve as the project grows. Material changes will update the "Last updated" date at the top of this page and will be visible in the public source repository's history alongside the website content. Your continued use of the site after a change means you accept the updated terms.

9. Governing law

These website terms are governed by the laws applicable to the primary maintainer of the project, without regard to conflict-of- laws principles. Nothing in these terms overrides consumer or statutory rights you may have under the law of your own jurisdiction.

10. Contact

Questions about these terms, or trademark permission requests, can be filed as an issue in the project's public repository at GitHub. Legal notices relating to the project should reference the same repository so that they reach the current maintainers.
