legal — terms of service
Terms of Service
These Terms of Service govern your use of delineo3d. They cover what you are buying, what you own, how your data is used, and the limits of what we promise. The Privacy Policy is part of this agreement.
1 Agreement
delineo3d is operated by Codestead LLC, a Utah limited liability company doing business as delineo3d (“delineo3d”, “we”, “us”). By creating an account or clicking to accept, you agree to these Terms of Service and to the Privacy Policy. We record each acceptance against the version tag shown above; the Terms of Service and Privacy Policy are versioned and accepted together, and one tag covers both documents. If you do not agree, do not use the service. Direct questions to [email protected].
2 The service
delineo3d is computer-aided design driven by conversation. You describe a part, and the service builds the model, produces engineering drawings, checks its work, and exports manufacturing files, revising across as many turns as the work requires. The service is in early access: features may change, be added, or be removed, and access may be limited by invitation. We may modify or discontinue the service; if we discontinue it, we will give notice, provide a reasonable window to export your work, and refund the unexpired portion of prepaid credit packs. We are not liable for delay or failure caused by events outside our reasonable control, including failures of the third-party providers in section 10.
3 Eligibility and accounts
The service is offered only to persons in the United States. You must be at least 18 years old and able to form a binding contract. You represent that you are not located in a jurisdiction subject to a United States embargo and are not on any United States government list of prohibited or restricted parties. Accounts are individual — one person, one subscription — and you may not share, pool, or resell access. Sign-in is handled through our identity provider. You are responsible for keeping your account secure and for all activity under it.
4 Plans, credits, and automatic renewal
Paid access is a monthly subscription, as described on the pricing page, plus optional one-time credit packs. Subscriptions renew automatically each month at the then-current plan price, plus any applicable tax, until you cancel. By subscribing, you authorize us to charge the payment method on file for each renewal.
- Where a plan offers a trial, the trial lasts 7 days and requires a payment card. Nothing is charged during the trial. If you do not cancel before the trial ends, the payment method on file is charged the plan’s monthly price, and the subscription renews monthly thereafter.
- You can cancel at any time, online, through the billing portal in your account settings. Cancellation takes effect at the end of the current billing cycle, with no further charges.
- Credits meter computation, and the amount a request consumes depends on the complexity of the work. Credits do not guarantee a number of prompts, parts, drawings, or successful results. We may adjust how much computation a credit buys as underlying costs change, with notice; credits you have already purchased keep their stated credit count.
- Credits included with a subscription expire at the end of the billing cycle in which they were granted. Trial credits expire when the trial ends. Pack credits expire 12 months after purchase, may be bought and spent only with an active paid subscription, and are spent after your included monthly credits.
- When your balance reaches zero, new work stops. We do not bill overages.
- Prices are in US dollars and exclude tax; any applicable tax is calculated at checkout. If a price increases, we will notify you no less than 7 and no more than 30 days before the increase applies, in a form you can keep, with the new amount and how to cancel; you can cancel before it takes effect.
5 Refunds
Except as section 2 provides, or where the law requires otherwise, payments are non-refundable. If we approve a refund, it reverses unused credits first; refunding value you have already spent may leave your account with a negative credit balance. A negative balance offsets future credit grants until it is recovered; it is never a cash debt you owe us.
6 Cancellation and access to your work
A subscription that has ended — by cancellation or non-payment — keeps read, review, measure, and export access to work you own, for as long as we operate the service. If we discontinue the service or an export format, section 2’s notice and export window apply. This access does not survive deletion of your account, so export your work first. It may be suspended for an account terminated for breach under section 14, and we may delete data in accounts with no sign-in for 12 months, after notice and an opportunity to export.
7 Your content, our license, and improving the service
As between you and us, your work is yours: we claim no ownership of your prompts, models, drawings, or exports, and you keep whatever intellectual-property rights the law recognizes in them.
You grant Codestead LLC two licenses. First, a worldwide, non-exclusive, royalty-free license to host, store, process, reproduce, transmit, and display your content as needed to operate the service, which ends when the content is deleted. Second, a perpetual, irrevocable, worldwide, non-exclusive, royalty-free license to use your content — your prompts, designs, conversations, corrections, and records of how you use the service — and to prepare derivative works from it, to develop and improve the service, including training and fine-tuning the machine-learning models that power it, including through the third-party providers that run them. There is no opt-out from this use, except where applicable law grants you a right that cannot be waived. If you have such a right, contact us: we will stop using your future content for training, and where the right cannot be honored for content already trained into a model, we will say so plainly and, on request, close your account and refund unused prepaid amounts. The Privacy Policy describes what is collected and how it is handled.
Models, model weights, fine-tuned checkpoints, and de-identified or aggregated datasets derived from the service belong to Codestead LLC. They survive cancellation, termination, and deletion of your content or account, and are not subject to reversal or unlearning: deleting content removes the stored content as the Privacy Policy describes, but it does not affect models trained before the deletion.
You represent that you own, or have all rights necessary to license, everything you submit, and that your submissions contain no third-party confidential information and no export-controlled technical data. We owe you no confidentiality obligation beyond what the Privacy Policy describes, and you must not submit material you are obligated to keep confidential.
If you send us feedback or suggestions, we may use them without restriction or obligation to you. We may show examples of service output in marketing materials in a form that does not identify you; write to us to exclude your work. The service itself — the software, interfaces, and underlying systems — remains the property of Codestead LLC and its licensors.
8 Acceptable use
Use the service only for lawful purposes. You agree not to:
- circumvent or interfere with credit metering, rate limits, or access controls;
- probe, scan, or attack the service, or access it by any means other than the interfaces we provide;
- scrape, harvest, or bulk-extract content that is not your own work;
- resell, sublicense, or share access to the service;
- upload content that infringes someone else’s rights or that you have no right to use;
- use the service to develop a competing CAD or design-automation product, or to generate training data for competing models — nothing here restricts what you do with your own designs, including manufacturing, selling, or distributing them;
- submit technical data controlled by United States export-control law (including ITAR or the EAR), or use the service in violation of United States export-control or sanctions law;
- design parts for the safety-critical applications described in section 11 without the independent professional review it requires;
- use the output to violate the law or the rights of others.
9 Copyright complaints
If you believe content on the service infringes your copyright, send a notice that complies with 17 U.S.C. § 512(c)(3) to [email protected]. We respond to valid notices, including by removing the identified material, we accept counter-notices under § 512(g) at the same address, and we terminate the accounts of repeat infringers.
10 Third-party services
The service is built on third-party providers, including AI inference providers, an identity provider, a payment processor, and cloud hosting. Payments are additionally subject to the payment processor’s own terms. We do not control third-party services and are not responsible for them.
11 Disclaimers
The service and its output are provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement.
Codestead LLC is not an engineering firm and does not provide professional engineering services. No output is reviewed, approved, or certified by a licensed engineer. You are responsible for verifying any design before you manufacture it, order parts from it, or otherwise rely on it.
The service is intended for parts where an error is recoverable, such as prototypes, fixtures, and one-off work. Do not rely on it for safety-critical applications — including life support, medical devices, aircraft, or structures whose failure could injure someone — without independent review by a qualified professional.
Some jurisdictions do not permit certain disclaimers; where the law grants you rights that cannot be disclaimed, those rights are unaffected.
12 Limitation of liability
To the maximum extent permitted by law, Codestead LLC will not be liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or the cost of manufactured parts, scrapped material, tooling, or shop time, arising from the service or its output — even if we have been advised such damages are possible. Our total liability for all claims in any 12-month period will not exceed the greater of the amounts you paid us for the service in that period or one hundred US dollars. Nothing in these terms limits liability that the law does not permit to be limited, including liability for fraud.
13 Indemnification
You will defend, indemnify, and hold harmless Codestead LLC and its members, officers, and agents from claims brought by a third party, and the resulting damages and reasonable legal fees, arising out of your content or your use of the service — except to the extent a claim results from our fraud, willful misconduct, or gross negligence.
14 Suspension and termination
You may stop using the service or delete your account at any time. We may suspend or terminate your access if you materially breach these terms, abuse the service, or where the law or the security of the service requires it. Credits are forfeited on termination for breach. If we learn you are ineligible under section 3, we will close the account and refund unused prepaid amounts. Section 6’s export commitment survives cancellation. Any provision that by its nature should survive — including sections 5 through 7, 9, and 11 through 18 — survives termination.
15 Changes to these terms
We may update these terms. Each version carries a version tag and effective date at the top of this page. We will give notice of material changes as section 17 describes and ask you to accept the new version before you start new AI work; for other changes, continued use after the effective date constitutes acceptance.
16 Governing law, arbitration, and class waiver
These terms are governed by the laws of the State of Utah, excluding its conflict-of-law rules.
Informal resolution first. Before starting arbitration, the party raising the dispute must send the other a written description of the claim — to [email protected], or to your account email — and allow 30 days to resolve it. This step does not apply to small-claims actions or the intellectual-property claims described below.
Binding individual arbitration. Any dispute arising out of these terms or the service that is not resolved informally will be settled by binding arbitration before a single arbitrator, administered by the American Arbitration Association under its Consumer Arbitration Rules and, for coordinated filings, its Mass Arbitration Supplementary Rules, each as in effect when the demand is filed; any applicable limitations period is tolled while a demand awaits administration under those rules. Arbitration is conducted remotely or in the county where you live, and the AAA’s rules govern fees. If the AAA is unavailable or declines to administer, the parties will agree on a substitute consumer-arbitration administrator, or either party may ask a court to appoint an arbitrator under 9 U.S.C. § 5. Either party may instead bring an individual claim in small-claims court, and either party may seek injunctive relief in court for infringement or misuse of intellectual property. Claims for public injunctive relief may be brought only in court; this sentence is severable from the rest of this section.
Class and jury waiver. Disputes will be resolved only on an individual basis. You and Codestead LLC each waive any right to a jury trial and any right to participate in a class, consolidated, or representative action. The arbitrator may not consolidate claims or preside over any form of representative proceeding except as the AAA’s Mass Arbitration Supplementary Rules provide. If the class-and-representative-action waiver is found unenforceable as to a dispute, the agreement to arbitrate is void as to that dispute and it will proceed in court; the unenforceability of any other part of this section, including the jury waiver, severs only that part.
Opt-out. You may opt out of arbitration, the class waiver, and the jury waiver by emailing [email protected] within 30 days of first accepting a version of these terms that contains this arbitration provision, or that materially changes it, stating your account email and that you opt out of arbitration. An opt-out is permanent and applies to all later versions of these terms. Opting out does not affect any other part of these terms.
17 Notices
You consent to receive agreements, notices, and disclosures from us electronically. We give notice in the service, effective when posted, and also by email where we can reach you through the address associated with your account with our identity provider. Legal notices to Codestead LLC go to [email protected] or by mail to Codestead LLC’s registered agent on file with the Utah Division of Corporations and Commercial Code.
California users: the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs may be contacted in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by telephone at (800) 952-5210.
18 General provisions
These terms and the Privacy Policy are the entire agreement between you and Codestead LLC concerning the service. If any provision is found unenforceable, the remaining provisions stay in effect. You may not assign this agreement; we may assign it, including the section 7 license, as part of a reorganization or sale of the business. Our failure to enforce a provision is not a waiver of it.
