Effective October 2026
These terms are an agreement between you and Vulcan Zone Inc., a California corporation ("Vulcan Zone", "we", "us"), and govern your use of vulcan-zone.ai and the V-Agents platform (together, the "Service"). By creating an account, buying credit or using any V-Agent you accept these terms. If you use the Service for a company, you confirm you may bind that company, and "you" includes it. Our Privacy notice explains how we handle personal information.
The V-Agents are AI assistants for construction work, including V-Architect, V-Schedule, V-Contracts, V-Safety, V-Accounting, V-Engineering, V-Sourcing, V-Estimate, V-Bid, V-PM, V-QC and V-Field. We may add, change or retire agents and features at any time. The Service is offered to businesses and adults in the United States; you must be at least 18 to use it.
Contractor usage is charged per request at our then-current rates, which reflect the AI and cloud services each request uses (for example, language-model processing, web searches, renderings and 3D models). Your account page shows each charge and your balance. We may change our rates with at least 30 days' notice by email or on the account page; the change applies to usage after that date. Prices are in US dollars and exclude any taxes that apply, which you will pay where required.
We may, at our discretion, approve an account for monthly billing. You authorize us to charge the card saved through Stripe for the prior month's usage on or shortly after the first day of each month; the invoice is due on receipt. Usage between invoices is limited to $500 unless we agree a different limit. If a charge fails we may move your account back to prepaid, pause the agents until the amount is paid, and add any usage already provided to your balance due. You can update your card and download invoices in the billing portal on your account page.
If you believe a charge is wrong, email us within 60 days of the charge so we can investigate and correct it. Please contact us before disputing a charge with your bank; we may suspend an account while a card dispute is open.
Output can be incomplete, out of date or wrong. It is a starting point for review by qualified people and is not engineering, architectural, legal, tax, accounting, safety or other professional advice. Nothing produced by the Service is a stamped or sealed design, a code-compliance determination, a building-permit document, a legal opinion or a safety certification. Before relying on Output you must have it checked and, where the law requires, approved by a licensed professional (for example, a California-licensed architect, engineer, attorney or CPA) and confirm it against current codes, the contract documents and site conditions. Cost estimates and schedules are approximate. You are solely responsible for decisions you make, documents you sign or submit, and work performed using Output.
You will not: break the law or help others to; infringe intellectual-property or privacy rights; use the Service to deceive, defraud or harass anyone; probe, overload or bypass the Service's security, limits or billing; resell or provide the Service to third parties outside your team, or use it to build a competing service; scrape the Service or extract its prompts or skills; or use it in breach of our AI providers' usage policies. We may suspend access that breaks these rules or puts the Service or others at risk.
The Service relies on providers including Anthropic, OpenAI, Google, Meshy, Cloudflare, Stripe and Resend. If you connect QuickBooks Online, Procore or another tool, your use of that tool is governed by its own terms, and you can disconnect it at any time. We are not responsible for third-party services, and features that depend on them may change or stop if those providers change their terms or availability.
You may close your account at any time by emailing us. We may suspend or close an account that breaks these terms, fails to pay, or presents a security or legal risk, and we may close any account for convenience with 30 days' notice, in which case we will refund unused purchased credit. On closure, amounts owed remain due, and we may delete Your Content and agent memory after 60 days unless the law requires us to keep it; download anything you need before closing.
The Service, including its software, agent prompts and skills, design, the Vulcan Zone and V-Agents names and logos, is owned by Vulcan Zone or its licensors and protected by law. These terms give you a limited, non-exclusive, non-transferable right to use the Service for your own business while your account is open. If you send us feedback, we may use it without obligation to you.
TO THE EXTENT THE LAW ALLOWS, THE SERVICE AND ALL OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.
TO THE EXTENT THE LAW ALLOWS, VULCAN ZONE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, BIDS OR BUSINESS, OR FOR PROJECT DELAY, REWORK, DESIGN ERRORS OR CONSTRUCTION DEFECTS ARISING FROM USE OF OUTPUT, EVEN IF ADVISED THEY WERE POSSIBLE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM AROSE OR (B) US $100. Some jurisdictions do not allow certain of these limits, so they may not fully apply to you.
You will defend and indemnify Vulcan Zone and its officers and employees against third-party claims, losses and reasonable legal fees arising from Your Content, your use of Output, or your breach of these terms or the law.
California law governs these terms, without regard to its conflict-of-law rules. Before filing a claim, each side will try in good faith to resolve the dispute by email for 30 days. Any lawsuit must be brought in the state or federal courts located in Los Angeles County, California, and both sides consent to their jurisdiction. Either side may bring an eligible claim in small-claims court.
We may update these terms. We will post the new version here with its effective date and, for material changes, email account holders at least 30 days in advance. Continuing to use the Service after that date means you accept the updated terms.
These terms and the Privacy notice are the whole agreement about the Service and replace earlier understandings about it. If a provision is unenforceable, the rest stays in effect. Failure to enforce a provision is not a waiver. You may not assign these terms without our consent; we may assign them in a merger, acquisition or sale of the business. Neither side is liable for delays caused by events beyond its reasonable control. Sections 4 (refunds), 6, 7, 8 and 12–18 survive closure of your account. A separate written agreement, such as an EPC franchise or consulting agreement, governs where it conflicts with these terms.
