Effective date: June 18, 2026

Terms of Service

Application: ArgilCAD (also presented as “AI3DModel”) (the “App” or “Service”).
Provider: ArgilDesign (“ArgilCAD”, “we”, “us”, or “our”).

Please read these Terms carefully. They contain disclaimers of warranties, limitations of our liability, and an obligation for you to indemnify us. By creating an account or using the App, you accept these Terms in full.

Order process & Merchant of Record. Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

1. Introduction and Acceptance

1.1. These Terms of Service (“Terms”) form a legally binding agreement between you (“you”, “your”, or the “User”) and ArgilCAD, operated by ArgilDesign, governing your access to and use of the App, including all AI-assisted 3D model and code generation features.

1.2. By downloading, installing, accessing, registering for, or using the App, you confirm that you have read, understood, and agree to be bound by these Terms and by any documents incorporated by reference (including our Privacy Policy). If you do not agree to these Terms, do not use the App.

1.3. If you use the App on behalf of an organization, you represent that you are authorized to bind that organization to these Terms, and “you” refers to that organization.

2. Definitions

“Service” / “App” — the ArgilCAD parametric CAD application and all related software, websites, viewers, APIs, and features.
“Prompt” / “Input” — any text, parameter, reference image, file, or other content you submit to the App to request generation or other processing.
“Output” — any result the App produces from your Input, including generated source code (e.g., build123d / Python code), 3D geometry, and exported model files (e.g., GLB, STEP, STL).
“Credits” — the usage units consumed when you use generation or other metered features of the Service.
“Account” — the authenticated or anonymous profile through which you access the Service.
“Third-Party AI Provider” — any external provider of large language models or related services used to process Inputs and produce Output.

3. Eligibility and Accounts

3.1. Age. You must be at least 18 years old, or the age of majority in your jurisdiction, and have the legal capacity to enter into these Terms.

3.2. Registration. Some features require an Account. You agree to provide accurate, current, and complete information and to keep it updated. You are responsible for all activity under your Account.

3.3. Anonymous use. Where the App permits anonymous or guest access, these Terms still apply to you in full.

3.4. Security. You are responsible for safeguarding your credentials and for any use of your Account. Notify us promptly of any unauthorized use. You may not share, sell, or transfer your Account.

3.5. One account. Unless we expressly permit otherwise, you may maintain only one Account, and you may not create Accounts to circumvent Credit limits, suspensions, or other restrictions.

3.6. Suspension and termination. We may suspend, restrict, or terminate your Account at any time if you violate these Terms, if required by law, or to protect the Service or other users.

4. The Service and the Nature of AI-Generated Output

4.1. How it works. The App lets you describe a part or object using a Prompt (and optional reference images). Your Prompt is transmitted to one or more Third-Party AI Providers, which generate parametric source code. That code is then executed to produce 3D geometry, which is exported to formats such as GLB, STEP, and STL and displayed in the App.

4.2. AI output is probabilistic and may be wrong. You acknowledge and agree that: (a) Output is generated automatically and is inherently probabilistic, experimental, and may be inaccurate, incomplete, unsafe, non-functional, or unsuitable for any particular purpose; (b) Output may not be unique to you; (c) Output, including generated code, may contain errors or defects, may fail to execute, and may produce geometry that is structurally unsound, not manufacturable, dimensionally inaccurate, or non-compliant with any standard or regulation; (d) You are solely responsible for independently reviewing, testing, validating, and verifying all Output — including by qualified engineering, safety, and legal review — before relying on it for any real-world, commercial, structural, medical, or manufacturing purpose.

4.3. No professional advice. The App does not provide engineering, architectural, safety, legal, or other professional advice.

4.4. Availability. The Service is provided on an “as available” basis. We may modify, suspend, or discontinue any part of the Service at any time.

5. Third-Party AI Providers and Sub-Processors

5.1. To provide the Service, your Prompts and reference images are transmitted to and processed by Third-Party AI Providers (which may include, among others, Anthropic, OpenAI, Google, and xAI) and supporting infrastructure providers (which may include, among others, Google Firebase / Google Cloud, Paddle, and RevenueCat).

5.2. Your use of features that rely on these providers may also be subject to their respective terms and policies. You are responsible for ensuring your Inputs are appropriate to transmit to such providers.

5.3. We do not control, and are not responsible or liable for, the acts, omissions, availability, accuracy, security, or data-handling practices of any third party.

6. Intellectual Property and Output Ownership

6.1. Your ownership of Output. As between you and ArgilCAD, and to the maximum extent permitted by applicable law, you own the Output you generate through the Service. We do not claim ownership of your Prompts or your Output.

6.2. Your responsibility for Output. You are solely responsible for your Prompts and your use of Output. Because Output is AI-generated, we do not warrant that Output is original, non-infringing, or protectable.

6.3. License you grant to us. You grant ArgilCAD a worldwide, non-exclusive, royalty-free, transferable, and sublicensable license to host, store, reproduce, modify, process, transmit, display, and otherwise use your Prompts and Output to operate, provide, secure, analyze, and improve the Service. This license survives termination to the extent required to operate or improve the Service or comply with law.

6.4. Our intellectual property. The App and all software, source code (other than Output you own), interfaces, designs, the “ArgilCAD” and “AI3DModel” names, and all related intellectual property are owned by us or our licensors. You receive a limited, revocable, non-exclusive, non-transferable license to use the App for its intended purpose.

6.5. Feedback. If you send us suggestions or feedback, you grant us an unrestricted, perpetual, irrevocable, royalty-free license to use it.

7. Acceptable Use

You agree that you will not, and will not permit anyone else to:

(a) use the App to design, generate, or facilitate the creation of weapons, weapon components, or any item whose manufacture, possession, or distribution is restricted or prohibited by applicable law;
(b) use the App for any unlawful, fraudulent, harmful, infringing, defamatory, or deceptive purpose, or to violate the rights of others;
(c) submit Inputs that are illegal, infringing, or that you do not have the right to submit;
(d) reverse engineer, decompile, or attempt to derive source code or underlying models of the App, except where this restriction is prohibited by law;
(e) attempt to extract or use any API keys, credentials, model weights, or secrets, or bypass any security or access controls;
(f) abuse, circumvent, or manipulate Credits, billing, rate limits, or usage metering, or use automated means except through interfaces we expressly provide;
(g) interfere with, disrupt, overload, or impair the Service;
(h) resell, sublicense, rent, lease, or commercially exploit the Service except as expressly permitted; or
(i) remove, obscure, or alter any proprietary notices.

8. Credits, Subscriptions, and Billing

8.1. Tiers and Credits. The Service offers tiers, currently a Free tier and a Pro tier, each with a monthly Credit allotment. Generation and certain other features consume Credits. Credit allotments, costs per action, and tier features may change at our discretion.

8.2. Credits have no cash value. Credits are a limited license to use features of the Service. They are non-transferable, non-refundable (except where required by law), and have no monetary value. Unused Credits may expire at the end of each billing period.
