Terms and Conditions

Last updated: April 4, 2026

These Terms and Conditions govern your access to and use of the SToFU Systems website and related public-facing communications. They are written to be practical: clear enough to be enforceable, broad enough to protect both sides, and specific enough to fit the way this site is actually used.

1. Acceptance of These Terms

By accessing, browsing, or using this website, submitting an inquiry, or otherwise interacting with the public-facing services made available through it, you agree to be bound by these Terms and Conditions and by our Privacy Policy.

If you do not agree with these Terms, you should not use the website or any public-facing functionality made available through it.

2. Who We Are

This website is operated by SToFU Systems S.L. (“SToFU,” “we,” “us,” or “our”), a company operating from Spain. The public site is intended to present our engineering services, technical articles, selected product information, and ways to contact us.

3. Scope of the Website

The website is informational and operational in nature. It may include:

• descriptions of engineering services and specialist capabilities;
• articles, blog content, and technical materials;
• contact and qualification flows;
• references to third-party tools, publications, partners, or external resources;
• information about products, SDKs, methods, and possible engagement models.

Nothing on the public website, by itself, constitutes a binding commitment to provide services, accept a project, achieve a technical outcome, reserve capacity, or enter into a commercial relationship. Any actual engagement requires separate mutual agreement.

4. Eligibility and Authority

You may use the website only if you are legally capable of entering into a binding arrangement under applicable law. If you interact with us on behalf of a company, fund, institution, or other organization, you represent that you have authority to do so or are otherwise authorized to make the relevant inquiry.

5. Permitted Use

Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable right to access and use the website for lawful purposes such as:

• learning about our services, products, and technical areas;
• reading public technical materials and blog content;
• contacting us about potential business cooperation or technical questions;
• evaluating whether SToFU may be a fit for your engineering needs.

This right is limited to normal website use. It does not include any right to resell access, mirror significant portions of the website, scrape the site at scale, use the site for competitive intelligence gathering through abusive means, or interfere with the site’s operation.

6. Prohibited Conduct

You agree not to:

• use the website in violation of any applicable law, regulation, sanction, or court order;
• attempt unauthorized access to the website, its infrastructure, or related systems;
• interfere with the website’s availability, stability, or security;
• circumvent or probe anti-spam, anti-abuse, or security controls;
• submit malicious code, exploit material, credential dumps, or harmful payloads through the public website;
• use bots, crawlers, or automation in a way that creates disproportionate load or disrupts operation;
• copy, frame, reproduce, republish, or systematically extract protected content except as allowed by law or our prior written consent;
• misrepresent your identity, your organization, or the purpose of your contact;
• submit personal data or confidential information about third parties without appropriate authority.

7. Contact Forms, Inquiries, and Pre-Contract Communications

The website may allow you to send inquiries, request technical review, or initiate a conversation about a potential engagement. When you use those features, you agree to provide accurate information and to use them in good faith.

Submitting an inquiry does not guarantee a response, acceptance of a project, pricing proposal, timeline commitment, or obligation to enter into negotiations. We may decide, in our sole discretion, whether to respond, continue a conversation, request more detail, refer you elsewhere, or decline the opportunity.

We may use reasonable anti-spam and anti-abuse measures to validate form submissions, and we may reject, throttle, or ignore traffic that appears automated, malicious, or otherwise inconsistent with legitimate use.

8. Confidentiality and Sensitive Submissions

We understand that many serious engineering conversations begin before full contracting. At the same time, the public website is not intended to serve as a substitute for a negotiated confidentiality framework.

Unless we explicitly agree otherwise in writing, your use of the public website or contact form does not by itself create:

• a non-disclosure agreement;
• a fiduciary duty;
• a legal advisory relationship;
• a managed security engagement;
• a formal client, vendor, contractor, or partnership relationship.

If you need to share material that is confidential, export-controlled, regulated, or otherwise sensitive, the correct path is to request an NDA or other suitable framework before transmitting such material. We ask that you do not send secrets, credentials, payment data, or personal data that is unnecessary for initial qualification through the public website.

9. Intellectual Property Rights

Unless otherwise stated, the website, its structure, design, text, graphics, branding, code elements, compilations, and original content are owned by SToFU Systems S.L. or its licensors and are protected by applicable intellectual property and unfair competition laws.

You may not, without prior written consent, except where applicable law allows otherwise:

• copy substantial portions of the site for republication or commercial use;
• modify, adapt, translate, or create derivative works from protected site content;
• remove copyright, trademark, attribution, or proprietary notices;
• use our name, branding, or visual assets in a misleading or approval-implying way.

Public technical articles and references may discuss third-party technologies, tools, platforms, libraries, or companies. All third-party names, marks, and logos remain the property of their respective owners.

10. Feedback and Suggestions

If you send us feedback about the website, service descriptions, content quality, product ideas, or general suggestions, you agree that we may review and use that feedback without any obligation to compensate you, provided that doing so does not override a separate written agreement between us.

This section is not a claim to ownership over your confidential business materials, project documents, or protected client data. It is intended to address general unsolicited suggestions and website-related feedback.

11. Third-Party Links and Tools

The website may contain links to third-party services, including external scheduling tools, social profiles, partner resources, public documentation, or other websites. Those services are controlled by third parties, not by us.

We are not responsible for the availability, content, security, accuracy, terms, or privacy practices of third-party websites or services. Your use of those services is governed by the terms and policies of the relevant third party.

12. Website Availability and Security

We may modify, update, suspend, restrict, or discontinue any part of the website at any time, with or without notice. We are not obligated to keep the site, any page, or any feature continuously available.

We reserve the right to implement protective controls, including request filtering, rate limiting, security checks, content moderation, abuse detection, or temporary blocks, in order to maintain service integrity and reduce malicious activity.

13. Disclaimers

The website is provided on an “as is” and “as available” basis. To the maximum extent permitted by law, we disclaim all warranties, conditions, and representations, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, availability, and accuracy.

Public technical content, blog articles, summaries of services, case-like examples, and engineering observations are provided for general informational purposes only. They are not guaranteed to be complete, current, suitable for your exact environment, or sufficient as a substitute for project-specific review, professional judgment, formal advice, or independent validation.

In particular, when the website discusses security, performance, reverse engineering, low-level systems, AI infrastructure, blockchain systems, HFT, or other complex domains, you should assume that context matters. The fact that a method, practice, or engineering pattern is described publicly on the site does not mean it is safe or appropriate for your environment.

14. Limitation of Liability

To the fullest extent permitted by applicable law, SToFU Systems S.L. and its officers, directors, employees, contractors, and affiliates will not be liable for any indirect, incidental, special, exemplary, punitive, or consequential damages, or for any loss of profits, revenue, business opportunity, goodwill, data, anticipated savings, or business interruption, arising out of or related to your use of or inability to use the website.

To the fullest extent permitted by law, our aggregate liability in connection with the website and these Terms will not exceed the greater of:

• one hundred euros (€100); or
• the amount, if any, that you paid directly to us solely for access to the specific website functionality giving rise to the claim, during the twelve months preceding the event that gave rise to the claim.

Because the public website is generally informational and not a paid SaaS product, this cap will in most cases be very low. Nothing in these Terms excludes liability that cannot legally be excluded under applicable law.

15. Indemnity

You agree to indemnify, defend, and hold harmless SToFU Systems S.L. and its officers, employees, contractors, and affiliates from and against claims, liabilities, damages, losses, costs, and expenses, including reasonable legal fees, arising out of or related to:

• your breach of these Terms;
• your misuse of the website;
• your violation of applicable law;
• content, data, or materials you submit through the website;
• your infringement or misappropriation of the rights of another person or entity.

16. Suspension and Termination

We may suspend, restrict, or terminate your access to the website, in whole or in part, at any time and without liability, especially if we believe that you have violated these Terms, created risk for the site, engaged in abusive behavior, or attempted unauthorized activity.

Termination or suspension does not affect provisions of these Terms that by their nature should survive, including provisions on intellectual property, disclaimers, limitations of liability, indemnity, governing law, and dispute resolution.

17. Compliance, Export, and Restricted Use

The subject matter presented on this site may relate to cybersecurity, low-level software, system internals, performance-sensitive infrastructure, reverse engineering, or other technically sensitive topics. You agree not to use the site or any information obtained from it in a way that violates export control laws, sanctions programs, anti-corruption laws, cybercrime laws, or other applicable legal restrictions.

You also agree not to request, use, or attempt to derive services from the site for unlawful surveillance, unauthorized intrusion, malware operations, credential theft, exploit deployment against unauthorized targets, or other improper activity.

18. Governing Law and Jurisdiction

These Terms and any non-contractual obligations arising from or related to them are governed by the laws of Spain, without regard to conflict-of-law rules.

Unless mandatory law requires otherwise, the competent courts of Spain will have exclusive jurisdiction over disputes arising out of or related to these Terms or the website.

19. General Provisions

19.1 Changes to These Terms

We may update these Terms from time to time. When we do, we will update the “Last updated” date at the top of this page. Continued use of the website after changes become effective means you accept the updated Terms, to the extent permitted by law.

19.2 Severability

If any provision of these Terms is held unenforceable, invalid, or unlawful, the remaining provisions will remain in full force to the maximum extent permitted by law.

19.3 Waiver

Our failure to enforce a provision of these Terms is not a waiver of that provision or any other provision.

19.4 Assignment

You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign these Terms in connection with a merger, reorganization, sale of assets, corporate restructuring, or transfer of the website or relevant business function.

19.5 Entire Agreement for Website Use

These Terms, together with the Privacy Policy and any other legal notice expressly incorporated by reference, form the complete agreement governing your use of the public website. Separate written agreements govern separate services and relationships.
