KruxOS End User License Agreement

This End User License Agreement (the "EULA" or "Agreement") is between you (the "Licensee", "you", "your") and Altvale ("Altvale", "we", "us", "our"). When Altvale is subsequently incorporated as a corporate entity, this Agreement will be reissued naming that entity as licensor and your rights under it will not be reduced by that transition.

In this Agreement:

• "KruxOS" or the "Software" means the closed-source KruxOS application distributed by Altvale, in object-code form, including any Documentation and any Updates we make available to you under this Agreement.
• "Documentation" means the user-facing documentation we publish for KruxOS (currently at docs.kruxos.com).
• "Updates" means patches, new versions, or replacements of the Software that Altvale makes available to you.
• "Extensions" means capabilities, plugins, themes, and similar components that interact with KruxOS through its published extension surfaces, whether published by Altvale, by you, or by a third party.
• "Open Extension Surfaces" means the parts of the KruxOS extension model that Altvale publishes as open-source repositories under a permissive licence (MIT or Apache 2.0, as marked on each repository).
• "Free Beta Period" means the period during which Altvale makes KruxOS available at no charge. The Free Beta Period is in effect at the Effective date of this Agreement and continues until Altvale notifies licensees otherwise as described in Section 4.

Subject to your compliance with this Agreement, Altvale grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable, royalty-free licence, valid worldwide, to:

• Install, run, and use the Software on devices that you own or otherwise lawfully control, for your personal, internal business, or research purposes;
• Make a reasonable number of back-up copies for archival purposes; and
• Use the Documentation in connection with the foregoing.

All rights not expressly granted in this Agreement are reserved by Altvale and its licensors. No licence is granted under any patent of Altvale except as is necessary to exercise the rights expressly granted in this Section 2.

Except as expressly permitted by this Agreement or by mandatory applicable law (including statutory rights of interoperability under the law of your residence), you will not, and will not authorise any third party to:

• Copy, modify, adapt, translate, or create derivative works of the Software, other than configuration and Extension work expressly permitted by the published extension surfaces;
• Reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Software;
• Sell, lease, rent, sublicense, distribute, host as a service, or otherwise commercially exploit the Software, in whole or in part;
• Remove, obscure, or alter any proprietary notice, label, mark, or notice of authorship in or on the Software or its outputs;
• Circumvent or attempt to circumvent any licence-management, access-control, or security feature of the Software;
• Use the Software to develop a product or service that is substantially similar to KruxOS, or to benchmark the Software for the purpose of publishing competitive comparisons without our prior written consent (other than legitimate journalism and independent research, which are not restricted);
• Use the Software in violation of any applicable law, including export-control, sanctions, anti-money-laundering, anti-corruption, and data-protection law; or
• Use the Software in any safety-critical context where its failure could reasonably be expected to lead to death, personal injury, or severe physical or environmental damage (including, without limitation, aircraft navigation, life-support systems, nuclear-facility operation, weapons control, or autonomous control of physical infrastructure).

During the Free Beta Period, this Agreement is offered at no charge. We may end the Free Beta Period at any time by giving at least thirty (30) days' advance notice on altvale.com/legal/kruxos-eula, in the KruxOS release notes, or by a release of the Software that displays the change on first run.

When the Free Beta Period ends:

• Versions of the Software you already have installed will continue to operate under the version of this Agreement under which they were licensed, subject to the survival of Sections 3, 7, 8, 9, 10, 11, 13, and 14.
• New versions, Updates, or features released after the Free Beta Period ends may be offered under separate paid terms, which Altvale will publish in advance. Acceptance of those new terms will be required before you install or use the relevant new version.
• Nothing in this Section retroactively imposes a payment obligation on you in respect of usage during the Free Beta Period.

Altvale publishes certain components of the KruxOS extension model — including capabilities, plugins, and themes — as open-source repositories under permissive licences (MIT or Apache 2.0, as marked on each repository). Those open-source components are governed by the licence shipped with each repository, and those licences prevail over this Agreement in respect of those components.

You are free to write, modify, publish, and distribute Extensions for KruxOS, including under any licence of your choice, provided that:

• You comply with the relevant Open Extension Surface licence in respect of any code you derive from it;
• You do not represent your Extension as being made or endorsed by Altvale unless we have agreed otherwise in writing; and
• Your Extension does not, by design, defeat any restriction in Section 3 of this Agreement.

Altvale claims no ownership over Extensions you author independently of Altvale source code, and no ownership over any data, configuration, prompts, or outputs that you produce by using KruxOS or its Extensions.

Your data. KruxOS runs on your machine. Inputs you provide (including prompts, files, and credentials), data the Software reads from your filesystem or network, and outputs the Software produces are yours. Altvale does not receive them in connection with this Agreement.

Third-party services. KruxOS can be configured to communicate with third-party services — for example, large-language-model providers, source-control hosts, productivity tools, and other APIs. Those services are not provided by Altvale, are governed by their own terms and privacy policies, and may charge fees independently. You are responsible for your use of and compliance with those services, including the lawful sourcing and handling of any data you submit to them.

AI outputs. Where KruxOS produces output generated wholly or partly by a machine-learning model (whether run locally or routed through a third-party service), those outputs may be inaccurate, incomplete, biased, or otherwise unfit for a particular purpose. Outputs are not professional, legal, medical, financial, safety, or other expert advice, are not warranted in any respect, and must not be relied upon without independent verification by a qualified person. You are solely responsible for any decisions or actions taken on the basis of any output of KruxOS.

Telemetry. At the Effective date of this Agreement, KruxOS does not transmit usage data, prompts, completions, file contents, or any other operational data to Altvale's infrastructure. If a future version of KruxOS introduces any such transmission, it will be disclosed in the Privacy Policy and gated behind an explicit opt-in.

Altvale may, at its discretion, release Updates to the Software. You are not obliged to install Updates, but Altvale may discontinue support for older versions and may publish security advisories that affect the safe usability of older versions.

Altvale offers no service-level commitment, support obligation, or response-time guarantee in respect of the Software during the Free Beta Period. Best-effort security correspondence is available at [email protected].

The Software is licensed, not sold. Altvale and its licensors retain all right, title, and interest in and to the Software, the Documentation, and all related intellectual-property rights, including all improvements, modifications, and derivative works thereof. "KruxOS", "KruxOrchestrate", "KruxAssist", and "Altvale" are unregistered trade marks of the operator. Use of those names or marks beyond fair use (such as factual reporting and legitimate commentary) requires our prior written permission.

Feedback. If you choose to send Altvale suggestions, ideas, or bug reports, you grant Altvale a perpetual, irrevocable, worldwide, royalty-free, sublicensable licence to use that feedback for any purpose, without attribution or compensation. You are not obliged to provide feedback.

THE SOFTWARE AND DOCUMENTATION ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, ALTVALE AND ITS LICENSORS DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, COMPLETENESS, QUIET ENJOYMENT, NON-INFRINGEMENT, OR THAT THE SOFTWARE WILL OPERATE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT DEFECTS WILL BE CORRECTED.

WITHOUT LIMITING THE FOREGOING, ALTVALE MAKES NO WARRANTY THAT THE OUTPUTS OF KRUXOS WILL BE ACCURATE, COMPLETE, OR FIT FOR ANY PURPOSE, AND MAKES NO WARRANTY IN RESPECT OF ANY THIRD-PARTY SERVICE TO WHICH YOU MAY DIRECT THE SOFTWARE.

Some jurisdictions do not allow the exclusion of certain warranties; in those jurisdictions, the foregoing exclusions apply only to the maximum extent permitted by law, and any non-excludable warranty is limited in duration to the minimum permitted by law.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL ALTVALE OR ITS LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, BUSINESS OPPORTUNITY, OR ANTICIPATED SAVINGS, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE SOFTWARE, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, STATUTE, OR ANY OTHER LEGAL THEORY, AND REGARDLESS OF WHETHER ALTVALE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

ALTVALE'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE SOFTWARE, FROM ALL CAUSES OF ACTION AND UNDER ALL THEORIES OF LIABILITY, WILL NOT EXCEED (A) THE TOTAL AMOUNT YOU PAID TO ALTVALE FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED US DOLLARS (USD 100), WHICHEVER IS GREATER. THE PARTIES AGREE THAT, GIVEN THAT THE SOFTWARE IS PROVIDED FREE OF CHARGE DURING THE FREE BETA PERIOD, THIS CAP IS A REASONABLE ALLOCATION OF RISK.

Nothing in this Section excludes or limits liability that cannot be excluded or limited under applicable law, including liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; and (c) any other liability that cannot be lawfully excluded or limited.

To the maximum extent permitted by law, you will indemnify and hold Altvale harmless from any third-party claim, demand, or damages (including reasonable legal fees) arising out of (a) your use of the Software in breach of this Agreement, (b) your infringement of any third-party right in connection with your use of the Software or its outputs, or (c) your use of any third-party service to which you direct the Software. We will give you prompt notice of any claim and cooperate reasonably in its defence.

This Agreement starts when you first install or use the Software and continues until terminated.

You may terminate at any time by ceasing to use the Software and deleting all copies in your possession or control.

Altvale may terminate this Agreement, or your licence under it, immediately on notice if you materially breach this Agreement (including any breach of Section 3) and either the breach is incapable of cure or, where capable of cure, you fail to cure within fourteen (14) days of notice. Altvale may also terminate at any time on at least thirty (30) days' notice for any reason or no reason; in such case, the licence terminates at the end of that notice period.

On termination, your licence ceases, and you must delete all copies of the Software in your possession or control within a reasonable period. Sections 1, 3, 5 (in respect of Extensions you have already published), 6, 8, 9, 10, 11, 13, and 14 survive termination.

You will comply with all applicable export-control, sanctions, and trade-restriction laws in your use of the Software. You represent that you are not located in, ordinarily resident in, or a national of a country or region subject to comprehensive sanctions by the United Nations, the United States, the United Kingdom, or the European Union, and that you are not on any government list of prohibited or restricted parties under those laws.

If the Software is acquired by or on behalf of a government entity, the licence is granted on the same terms as set out in this Agreement, with no additional or different government-specific rights granted.

This Agreement and any non-contractual obligations arising out of or in connection with it are governed by the laws of England and Wales, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Any dispute arising out of or relating to this Agreement may be brought before the competent courts of England and Wales, which shall have non-exclusive jurisdiction. Nothing in this Section prevents either party from seeking urgent injunctive or other equitable relief from any court of competent jurisdiction in respect of a breach or threatened breach of intellectual-property rights or confidentiality obligations.

Where you are a consumer resident in a jurisdiction whose mandatory consumer-protection law would, in the absence of this clause, give you the right to bring proceedings in your local courts under the law of your residence, nothing in this Section deprives you of that right.

Entire agreement. This Agreement, together with the documents it references, is the entire agreement between you and Altvale concerning the Software and supersedes any prior agreement on the same subject.

Severability. If any provision is held unenforceable, the remainder remains in effect.

No waiver. Failure to enforce any provision is not a waiver of that provision.

Assignment. You may not assign this Agreement without our prior written consent. We may assign this Agreement to any successor entity (including any corporate entity that succeeds the current sole-trader operation), or in connection with a merger, acquisition, or sale of substantially all of our assets.

Force majeure. Neither party is liable for failure or delay caused by events beyond its reasonable control.

Changes to this Agreement. We may revise this Agreement by publishing a new version on this page with a revised Effective date and a bump to the version number. Material changes will be summarised in the Plain summary banner for at least thirty (30) days. Continued use of new versions of the Software after the effective date of a change constitutes acceptance of the updated Agreement; the previously-licensed version continues under the version of the Agreement under which it was licensed.
