Terms of Use

Effective date: October 24, 2026

These Terms of Use apply to duffion.com, operated by Duffion LLC. They explain the permitted use of this website and how website inquiries relate to paid engagements. Please read them alongside our Privacy Policy.

Website information and project engagements

This website describes our experience, capabilities and selected work. It is provided for general information. Submitting a form, sending an email or booking a meeting does not by itself create a project agreement, reserve delivery capacity or commit either party to a price or deadline.

The proposal, statement of work or other agreement accepted for that engagement governs paid work. That agreement determines deliverables, fees, payment, intellectual-property rights, confidentiality, support and any project-specific terms. If it conflicts with these website terms on a project matter, the project agreement controls.

Portfolio and availability

Portfolio examples describe specific work and may include historical or retired systems. Features, results and timelines from one engagement are not guarantees for another. Client names, logos and third-party trademarks belong to their respective owners; their appearance does not imply an endorsement or a current relationship beyond what the relevant case study states. Availability and service descriptions may change.

Permitted use

You may browse the website and use it to learn about our work and contact us. Do not use it to break the law, impersonate someone, submit information you have no right to disclose, send spam or malicious code, gain unauthorized access, or disrupt the website or its services. We may restrict abusive access to protect the site and its users.

Content and intellectual property

Duffion LLC owns the website text, design and original materials or uses them with permission, except where we identify another owner or license. You may link to public pages and use materials as permitted by applicable law or an identified license. Other copying, redistribution or commercial reuse requires permission from the relevant rights holder. These terms do not transfer rights in client work, third-party software or trademarks.

Inquiries and information you submit

Provide accurate contact information and only submit material you are authorized to share. We use inquiries to respond and discuss the requested work, as described in our Privacy Policy. Do not include passwords, payment-card details or highly sensitive information in a general inquiry. If a project requires confidential materials, arrange an appropriate secure channel and any necessary confidentiality agreement first.

Third-party services and links

The website may link to client work, scheduling tools, documentation and other third-party services. Those services have their own terms and policies. Duffion does not control their availability, content or practices.

Quark operator SMS

Quark uses Twilio to send operational SMS notifications to its operators. These notifications are not a public marketing subscription, and a website inquiry does not enroll you. Message frequency depends on operational activity; your carrier’s message and data rates may apply. Delivery depends on Twilio and telecommunications networks and may be delayed or unavailable. Do not rely on these messages as an emergency communications service.

Operators can contact [email protected] for messaging help or to stop notifications. The Privacy Policy describes related information handling. These website terms do not replace any separate Quark operator or service agreement.

Website availability and limitations

We aim to keep website information accurate and available, but it may contain errors, become outdated or be interrupted. To the extent permitted by applicable law, this informational website is provided as available without a guarantee of uninterrupted access, complete accuracy or suitability for a particular purpose. Nothing here excludes rights or responsibilities that cannot lawfully be excluded, or changes obligations in a separate project agreement.

Changes and contact

We may update these website terms by posting a revised version with a new effective date. Changes to these website terms do not automatically amend an existing project agreement. For questions, permissions or concerns, contact Duffion LLC at [email protected] or visit our contact page.
