Licensor and publisher: ITEXPERT24 LTD, a company registered in England and Wales under company number 17110917, with its registered office at 71-75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom ("ITEXPERT24", "we", "us" or "our").

1. Agreement and scope
This End User License Agreement ("Agreement") governs your installation and use of the GoldenKube command-line software, including its executable, updates, documentation, and original examination-practice content bundled with it (the "Software"). GoldenKube is free to use but proprietary and closed source. It is not released under an open-source license.
Please read this Agreement before using the Software. By selecting the acceptance option during first use, you agree to it. If you do not agree, do not use the Software and uninstall it. You may view the Agreement and use informational commands, such as the license, help and version commands, without accepting it.
The GoldenKube website and account services may also be governed by their own Terms of Use at https://goldenkube.dev/terms. This Agreement governs the downloadable CLI; where a separate service is involved, the applicable service terms also apply. Nothing in this Agreement overrides your mandatory rights under applicable law.
2. Free license and permitted uses
Subject to this Agreement, ITEXPERT24 grants you a limited, non-exclusive, worldwide, non-transferable, non-sublicensable, royalty-free license to download, install and run the Software on devices you lawfully control, for:
- personal study and certification-examination practice;
- professional skill development; and
- internal use by businesses and other organisations, including their staff's internal training and assessment.
There is no license-key fee or per-device charge for this free edition of the Software (the "Free Edition"). Users must use their own GoldenKube accounts where authentication is required. This Agreement does not grant access to paid products or features that may be offered separately in the future.
3. Ownership and restrictions
The Software, its original scenarios, task descriptions, grading logic, documentation, marks and other proprietary materials are owned by or licensed to ITEXPERT24 and its respective licensors. You receive permission to use them, not ownership of them. Your independently created files, notes, Kubernetes manifests and other original work remain yours.
Except where expressly permitted by this Agreement, a separate written permission from ITEXPERT24, a third-party license, or applicable law, you must not:
- sell, rent, sublicense, publish, distribute, rebrand or commercially redistribute copies of the Software or its proprietary content;
- offer the Software or its proprietary scenario bank to third parties as a white-label, hosted, resold or competing examination-practice service;
- reproduce or publish substantial portions of GoldenKube's original scenario bank, grading scripts, answer keys or proprietary explanations as your own product or dataset;
- modify or create derivative versions of the proprietary Software for redistribution, or remove proprietary notices; or
- bypass authentication, access controls, rate limits or technical protections, or misuse the online services or another user's account.
You may make copies reasonably necessary for lawful use and backup. Nothing above restricts acts that the law expressly permits notwithstanding contractual restrictions, including any applicable rights relating to interoperability, or permissions granted under third-party open-source licenses. These restrictions do not prevent you from discussing general Kubernetes concepts or using knowledge you acquire independently.
4. Accounts and online features
Some features require a free GoldenKube account, internet connectivity and access to GoldenKube services. You are responsible for protecting your account credentials and for activity under your account, except where that responsibility cannot legally be placed on you.
We may reasonably restrict access to online features where necessary to address security incidents, abuse, breaches of these terms or legal obligations. Where practicable, we will provide notice and a way to contact us. We do not promise that every online feature, exam catalog or account service will remain available indefinitely. Material changes to existing services will be communicated as required by applicable law.
5. Local virtual machines and third-party software
GoldenKube creates, configures, starts, stops and may delete local virtual machines and examination environments when you expressly use relevant commands. Those operations can use substantial CPU, memory, storage and network resources. Inside those virtual machines (never on your host system) GoldenKube downloads and installs third-party software from its respective distributors, including Ubuntu/Linux components, Kubernetes components and related utilities; on the host it only drives Multipass, which you install yourself.
Check the commands and available disk space, keep appropriate backups, and do not use GoldenKube on production systems as an operational management or disaster-recovery tool. Operations that delete lab environments may remove lab data. We will aim to document the effects of destructive commands clearly.
Third-party software and components are governed by their own licenses. Their notices are available in the distribution's THIRD-PARTY-NOTICES.md, where applicable, and from the relevant third-party projects. This Agreement does not restrict rights granted by those licenses.
6. Privacy and data
Use of account-connected features involves processing personal data such as account identifiers, authentication information, examination attempts and progress data, as explained in the GoldenKube Privacy Notice at https://goldenkube.dev/privacy and in any CLI-specific privacy notice made available through the installation materials.
This Agreement is not consent to optional analytics or marketing. Where consent is legally required, it must be requested separately. For privacy requests, contact hello@goldenkube.dev.
7. Free Edition and future commercial offerings
The GoldenKube CLI Free Edition covered by this Agreement is supplied without a software license fee. We may offer optional paid editions, subscriptions, team features or commercial licenses in the future. We will not begin charging you automatically for the Free Edition without a separate transaction or clear affirmative agreement.
Any future paid offering will have its own pricing and applicable terms. An update or new service may have different availability or eligibility conditions. Changes will not retrospectively remove non-excludable rights that you already have.
8. Updates and changes to this Agreement
We may issue updates, corrections, security patches or new versions. We are not promising any particular update schedule. Some online features may require a compatible version to remain secure and operational.
For material changes to this Agreement affecting your future use, we will provide reasonable notice and request renewed acceptance where appropriate. Merely publishing a revised text will not itself amount to your acceptance of material new terms. The version of this Agreement accepted for a particular release will be recorded where reasonably necessary to administer the license.
9. Examination and affiliation disclaimer
GoldenKube provides independent practice environments, sample tasks and automated grading. Examination objectives, formats, permitted tools and passing requirements may change. The Software and its results are not official examination materials and do not guarantee certification or examination success.
GoldenKube is independent and is not affiliated with, endorsed by or sponsored by the Cloud Native Computing Foundation (CNCF) or The Linux Foundation. Kubernetes, Linux Foundation, CNCF and certification names are used for factual identification of relevant technologies and examinations; the respective names and marks belong to their owners.
10. Warranty and liability
The Software is provided free of charge and may contain errors, incomplete materials or features identified as previews. We do not promise uninterrupted availability, freedom from all defects, or any particular examination result. To the extent permitted by law, no additional warranties are given beyond those expressly stated or legally required.
Consumers. Nothing in this Agreement excludes or limits consumer rights that cannot legally be excluded or restricted, including applicable remedies for damage to a device or other digital content caused by a failure to exercise reasonable care and skill. We remain responsible for reasonably foreseeable loss or damage caused by a breach of our legal obligations, as required by applicable law. We do not exclude or limit liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or any other matter that the law does not allow us to exclude or limit.
Business users. To the fullest extent permitted by law, neither party is responsible to the other for indirect or consequential losses, or for loss of business profit, revenue or anticipated savings arising out of use of the Free Edition. Subject to the preceding exclusions for liability that cannot legally be restricted, ITEXPERT24's aggregate liability to a business user arising out of or in connection with the Free Edition will not exceed GBP 100. The enforceability and reasonableness of this business limitation must be confirmed by legal review before publication.
11. Suspension, termination and effect
This Agreement remains in effect until terminated. You may terminate your license at any time by ceasing use and removing copies of the proprietary Software in your possession. We may terminate the license for a material breach that remains unremedied after reasonable notice, unless immediate action is reasonably necessary to prevent security harm, misuse or unlawful activity.
Termination does not affect accrued rights, statutory remedies or the terms necessary to give effect to ownership, liability, dispute resolution and other provisions that by their nature survive termination. Removing the Software does not automatically remove any local virtual machines or delete your online account or progress; use the documented cleanup and account-deletion procedures.
12. Governing law and disputes
This Agreement is governed by the laws of England and Wales. If you are a consumer resident elsewhere, this clause does not deprive you of mandatory consumer protections that apply in your country of habitual residence, or of any right to bring proceedings in a court made available by mandatory law. Business disputes will be subject to the courts of England and Wales unless mandatory law requires otherwise.
13. General terms and contact
If a provision of this Agreement is found unenforceable, the remaining provisions continue to apply to the extent legally permitted. A failure to enforce a right immediately does not necessarily waive that right. This Agreement does not assign ownership of any third-party software to ITEXPERT24.
