Terms of
Service.

Stelvox Technologies ("Stelvox", "we", "us", "our") is an engineering studio registered in the United Kingdom. We provide software engineering and consulting services across AI, automotive software, custom applications, and cybersecurity.

Contact: hello@stelvox.com.

By placing an order, configuring a build, booking a Strategy Session or Discovery Sprint, or otherwise engaging our services, you ("the Client", "you") agree to these Terms of Service ("Terms").

We offer engineering services in four verticals: AI, Automotive, Applications, and Security. Specific deliverables, timelines, and acceptance criteria are described in:

• →The public configurator at /configure (productised services with fixed prices);
• →Each Statement of Work (SOW) executed under a Master Services Agreement (MSA) for larger engagements;
• →The Strategy Session and Discovery Sprint product pages for standalone consults.

Where a configurator order exists alongside a SOW, the SOW prevails for that engagement.

All prices are stated in GBP unless agreed otherwise, and are converted at render time for display in EUR, USD, AED, or TRY where appropriate. The amount charged is the GBP equivalent at the merchant of record's exchange rate at checkout.

Payments for productised services are processed through our merchant of record (Paddle.com Market Limited or, where listed, Lemon Squeezy / Squarespace Inc.). The merchant of record is the seller of record for VAT/sales-tax purposes and will appear on your statement and invoice.

Enterprise engagements may instead be invoiced directly under NET 30 or NET 60 terms (see /enterprise). Invoices are due from issue date; overdue invoices accrue interest at the Bank of England base rate + 4% per annum, calculated daily.

The first milestone is paid in advance. Subsequent milestones are paid on completion of the previous milestone, per the SOW.

Our refund terms are described in detail in our Refund Policy at /refund. In summary:

• →We offer a first-milestone money-back guarantee if the deliverable does not match what was scoped in the configurator or SOW.
• →Strategy Session and Discovery Sprint fees are credited toward subsequent engagements rather than refunded once delivered.
• →Refund requests are handled within 5 business days of receipt at hello@stelvox.com.

All work product created specifically for you under an order or SOW vests in you upon full payment of the relevant invoice. You receive complete, perpetual, worldwide ownership of those deliverables.

Stelvox retains ownership of:

• →Pre-existing tools, libraries, frameworks, and patterns that we use across multiple engagements;
• →Generic engineering know-how, methodologies, and reusable code;
• →Internal training material derived from anonymised, aggregated experience.

Where any pre-existing material is embedded in the delivered work product, we grant you a non-exclusive, perpetual, worldwide, royalty-free licence to use it as part of that work product.

Open-source components used in the work product are listed in the SOW's licences appendix.

You agree not to:

• →Use Stelvox services to develop or operate systems that are unlawful in your jurisdiction or ours;
• →Resell, white-label, or sublicense access to a Stelvox engagement without written consent;
• →Provide false information in the configurator, contact form, or any onboarding document;
• →Use any AI scoping or quote endpoint for automated scraping, denial-of-service, or competitive intelligence;
• →Attempt to circumvent our pricing (e.g. by configuring multiple sub-engagements to evade the founding-client discount cap).

Each party will treat the other's non-public information as confidential during the engagement and for three years after termination. Standard exclusions apply: information that is public, independently developed by the receiving party, or required to be disclosed by law.

For sensitive engagements we operate with segregated infrastructure, audit logging, and strict data-handling. The Data Processing Addendum (DPA) attached to the MSA governs handling of personal data.

We warrant that services will be performed with the reasonable care and skill expected of a senior software engineering studio.

We warrant that work product will substantially conform to the configurator scope or SOW for 90 days from delivery acceptance. Remedy for breach of this conformance warranty: we will, at our option, repair, replace, or refund the relevant portion of the fee.

We warrant that, to our knowledge, the work product does not infringe any third-party intellectual property right.

No other warranties, express or implied, apply. To the maximum extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

To the maximum extent permitted by law, neither party is liable for indirect, incidental, consequential, special, or punitive damages, or for lost profits or revenue.

Each party's aggregate liability under or in connection with these Terms is capped at the total fees paid to Stelvox under the relevant order or SOW in the twelve months preceding the claim.

This cap does not apply to: indemnification obligations under §10, breaches of confidentiality, infringement of intellectual property rights, fraud, gross negligence, death or personal injury caused by our negligence, or any liability that cannot be excluded by applicable law.

We will indemnify you against third-party claims that the work product, as delivered, infringes a third-party intellectual property right, provided you (a) give us prompt written notice, (b) let us control the defence, and (c) cooperate reasonably.

We may, at our option, modify the work product to be non-infringing, procure a licence, or refund the relevant fee.

Either party may terminate an engagement for convenience on 30 days' written notice. Either party may terminate for material breach on 14 days' written notice if the breach is not cured.

On termination, you pay for all services performed up to the termination date. We deliver all completed work product. Sections of these Terms that by their nature survive termination (IP, confidentiality, liability, indemnification, governing law) continue in force.

We may update these Terms from time to time to reflect changes in our services, the law, or operational practice. Material changes will be notified to active clients via the email on file at least 14 days before they take effect.

Continued use of our services after an update constitutes acceptance of the updated Terms.

These Terms are governed by the laws of England and Wales. Each party submits to the exclusive jurisdiction of the courts of England and Wales for any dispute arising under or in connection with these Terms, except that we may seek injunctive relief in any court of competent jurisdiction to protect our intellectual property or confidential information.

Where mandatory consumer-protection rules of your country of residence apply, those rules prevail to the extent of any inconsistency.

Questions, complaints, and notices under these Terms should be sent to hello@stelvox.com. We respond within five business days.
