Keymark End User License Agreement

Version 1.0 · Effective October 7, 2026

This End User License Agreement ("Agreement") is between you and KEY LAB TECHNOLOGY S.A.S. ("Key Lab", "we", "us"), a Colombian company with NIT 902.055.710-1 and its registered address at Calle 28 No. 84-195, Medellín, Antioquia, Colombia. It governs your use of the Keymark desktop application, including its updates, documentation and the components installed with it (the "Software").

Please read it before installing. By installing, copying or using the Software you accept this Agreement. If you do not accept it, do not install or use the Software. If you accept it on behalf of a company or other organization, you confirm that you are authorized to bind it, and "you" means that organization.

In plain words

You can install and use Keymark on your own devices, for personal or work purposes.
Keymark is licensed, not sold. Key Lab keeps all rights to the Software.
Don't copy, resell, redistribute or reverse engineer it, except where the law allows you to.
Your documents are yours. Keymark processes them on your device; we don't get them.
Keymark is in beta and its AI can be wrong. Keep backups and check important answers.
Colombian law applies. Your rights as a consumer under mandatory law are not affected.

This summary helps you read the Agreement; the numbered sections below are what bind you and us.

1. License

1.1. Subject to this Agreement, Key Lab grants you a personal, worldwide, non-exclusive, non-transferable and non-sublicensable license to install and use the Software in object-code form on computers that you own or control, for your personal use or for the internal purposes of your organization.

1.2. Some features or editions of the Software may require a paid license, a license key (such as a "Founder Key") or a subscription. Those will be offered under additional terms that you accept when you buy them. If they conflict with this Agreement on that subject, the additional terms prevail.

1.3. Key Lab may change, add or remove features in new versions. Key Lab's Core Promise, published on the Keymark website, describes the features that will remain free.

2. Ownership

2.1. The Software is licensed, not sold. Key Lab and its licensors own all rights, title and interest in the Software, including copyright, trade secrets and other intellectual property rights. All rights not expressly granted to you are reserved.

2.2. The source code of the Software is confidential and a trade secret of Key Lab. This Agreement does not give you any right to it.

2.3. "Keymark", the Keymark logo and "Key Lab" are trademarks of Key Lab. This Agreement grants no right to use them.

2.4. If you send us suggestions or feedback, we may use them without obligation to you. You keep ownership of anything you send us; you just let us use the idea.

3. Restrictions

Except as expressly allowed by this Agreement, by the license of a third-party component (Section 6), or by applicable law that cannot be waived by contract, you may not:

a) copy the Software, except for the installation copies allowed by Section 1 and reasonable backups;

b) reverse engineer, decompile, disassemble, decrypt or otherwise try to derive the source code, structure or algorithms of the Software, including extracting its application code or resources from the installed bundle, except and only to the extent that applicable law expressly permits it despite this restriction (for example, to achieve interoperability);

c) modify, translate, adapt or create derivative works of the Software;

d) distribute, publish, sell, rent, lease, lend, sublicense, transfer or otherwise make the Software available to others, including as a hosted service, as part of another product or through download sites;

e) remove, alter or hide any copyright, trademark, license or other notice in the Software;

f) bypass, disable or interfere with license keys, code signing, update signatures or other technical protections of the Software;

g) use the Software to develop a competing product by copying its non-public features, design or code; or

h) use the Software in breach of applicable law, including export control and sanctions laws.

4. Your documents and data

4.1. Your content stays yours. Key Lab claims no rights over the documents, notes, questions or other content you open, write or create with the Software ("Your Content").

4.2. Local processing. The Software reads, indexes and analyzes Your Content on your device, including with its built-in AI model. Key Lab does not receive Your Content unless you send it to us yourself (for example, attached to a support email).

4.3. Features that use the internet. Some features connect to the internet: checking for and downloading updates, downloading optional AI models from Hugging Face, optional anonymous usage statistics, loading images that your documents reference on the web, opening links, and AI servers that you configure yourself. The Keymark Privacy Policy explains each of them. Offline mode turns them off, except opening a link, which hands it to your web browser.

4.4. AI servers you configure. If you connect the Software to an AI server that is not on your device, the text you ask about (for example, a document, a selection or your question) is sent to that server. That server's operator, not Key Lab, is responsible for it, and its own terms and privacy policy apply.

4.5. Backups. You are responsible for keeping backups of Your Content. The Software is designed never to write into your folders except when you save or export, but no software is free of errors.

5. AI features

5.1. The Software includes AI features that run a language model on your device (and, if you choose, on servers you configure). AI output can be inaccurate, incomplete, outdated or inappropriate, even when it cites sections of your documents.

5.2. You are responsible for how you use AI output. Check it before relying on it, especially for legal, medical, financial, safety or security decisions. AI output is not professional advice.

5.3. The Software never runs commands for you. Features that extract tasks or shell commands from documents (such as the Run sheet) only show them; if you run a command yourself, you do so at your own risk.

5.4. You must not use the AI features to break the law or to violate the rights of others.

6. Third-party components

6.1. The Software includes components owned by third parties, such as open-source libraries, fonts, the llama.cpp runtime and the Qwen3 4B Instruct 2507 AI model, branded in the app as "Keymark AI" (Apache License 2.0). Each one is licensed under its own terms, listed in the third-party notices included with the Software (THIRD_PARTY_NOTICES.md, available from the app) and on request at [email protected].

6.2. Those licenses govern those components. Nothing in this Agreement limits the rights that a third-party license gives you over the component it covers, and if this Agreement conflicts with such a license on that component, the third-party license prevails for that component only.

6.3. Optional AI models you download through the Software are provided by their authors under their own licenses, which the Software shows before you download them. Key Lab does not provide them and is not responsible for them.

7. Updates

7.1. Key Lab may provide updates, but is not obliged to. Updates are signed by Key Lab and are covered by this Agreement unless they come with other terms.

7.2. The Software checks for and installs updates as described in its settings and in the Privacy Policy. Older versions may stop receiving fixes, and Key Lab may block versions with serious security issues from being offered as updates.

8. Pre-release software

8.1. The Software is currently pre-release software ("beta", including the Founders Beta). It may contain errors, lose or corrupt data, change significantly or be discontinued, and it may not work on every device.

8.2. Use pre-release versions at your own risk, keep backups, and do not rely on them where failure could cause significant harm.

9. Warranty disclaimer

9.1. To the maximum extent permitted by applicable law, the Software is provided "as is" and "as available", with all faults and without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, quiet enjoyment and non-infringement. Key Lab does not warrant that the Software will be uninterrupted, error-free or secure, or that AI output will be correct.

9.2. Consumer rights. Nothing in this Agreement excludes or limits rights that you have as a consumer under mandatory law, including, where applicable, Colombia's Estatuto del Consumidor (Ley 1480 de 2011). Where such law applies, the disclaimers and limits in Sections 9 and 10 apply only to the extent that law allows.

10. Limitation of liability

10.1. To the maximum extent permitted by applicable law, Key Lab and its shareholders, directors, employees and suppliers will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, profits, revenue, business or goodwill, arising out of or related to the Software or this Agreement, even if advised of their possibility.

10.2. To the maximum extent permitted by applicable law, Key Lab's total liability arising out of or related to the Software or this Agreement is limited to the greater of (a) the amount you paid Key Lab for the Software in the twelve (12) months before the event giving rise to the claim, and (b) fifty U.S. dollars (USD 50) or its equivalent in Colombian pesos.

10.3. These limits do not apply to liability that cannot be limited under applicable law, such as liability for willful misconduct (dolo) or gross negligence (culpa grave), or for personal injury caused by Key Lab's fault.

11. Term and termination

11.1. This Agreement applies from the moment you accept it until it ends.

11.2. You may end it at any time by uninstalling the Software and deleting your copies.

11.3. It ends automatically, without notice, if you materially breach it (in particular, Section 3). Key Lab may also end it by notice if required by law.

11.4. When it ends, you must stop using the Software and delete it. Sections 2, 3, 4.1, 6, 9, 10, 11.4, 12 and 13 survive. Ending this Agreement does not affect Your Content, which stays on your device.

12. Governing law and disputes

12.1. This Agreement is governed by the laws of the Republic of Colombia, without regard to conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

12.2. Before going to court, please write to [email protected] so that we can try to solve the problem directly.

12.3. The courts of Medellín, Colombia, have jurisdiction over disputes arising from this Agreement. This does not prevent you, if you are a consumer, from bringing a claim before the Superintendencia de Industria y Comercio or the courts of your domicile when the law allows it, or from enjoying the protection of the mandatory laws of the country where you live.

13. General

13.1. Entire agreement. This Agreement, together with the Privacy Policy and any additional terms under Section 1.2, is the entire agreement between you and Key Lab about the Software.

13.2. Changes. Key Lab may update this Agreement. The new version applies to versions of the Software released after it is published; Key Lab will show it in the app or on its website, and if you keep using those versions you accept it. If a change is material and you do not accept it, you may stop using the Software.

13.3. Severability and waiver. If a provision is found invalid or unenforceable, it will be limited to the minimum extent necessary and the rest remains in effect. Failing to enforce a provision is not a waiver.

13.4. Assignment. You may not transfer this Agreement without Key Lab's written consent. Key Lab may transfer it as part of a merger, acquisition or sale of assets, with notice to you.

13.5. Language. This Agreement is available in Spanish and English. If they differ, the Spanish version prevails.
