Terms of Service

1. Who we are

CADdillo is a product of Quantum Armadillo, LLC, a Texas company. This site is caddillo.com and the drafting app is at app.caddillo.com. Using either means you agree to these terms. If you do not agree, do not use CADdillo.

2. Accounts

Sign-in is by emailed magic link — there is no password, so there is nothing for us to store or for someone else to guess. Keep your email account secure; anyone who can read your email can sign in as you.

• One account per person. Creating multiple accounts to get around free-tier limits (the signup credit grant, the free DWG export limit) is not allowed — see §6, Acceptable use.
• You are responsible for everything that happens under your account, including drawings created, credits spent and charges made, whether or not you personally took the action.
• Minimum age: you must be at least 13 years old to create an account. The privacy policy currently states we do not knowingly collect data from children under 13 — pick the number that policy should actually enforce and this line will match it.

3. Credits and paid plans

CADdillo's AI drafting is metered in credits. This section states the rules as the billing system actually enforces them.

What credits are and what they cost

• New accounts get a one-time signup grant of 50 credits.
• Different actions cost different numbers of credits. A simple command or edit costs few; a full AI generation costs more; passes that involve image review or unusually heavy processing cost more still. The credit cost of an action is shown in the app before you take it, and that displayed cost is the authoritative one.
• Credit costs are variable and subject to change without notice. What an action costs depends on the AI models it runs on, the size and complexity of your request, and the rates our upstream model providers charge us — all of which change over time and outside our control. We work to keep costs down, but we do not guarantee any particular credit price for any action, and any rate quoted in marketing material, documentation or support correspondence is indicative only and not a contractual commitment. The in-app cost shown at the moment you act governs.
• Credits have no cash value. They cannot be redeemed for cash, transferred to another account, or resold.
• Credits from a purchased pack or a Pro plan do not expire while your account is open, unless a specific grant states otherwise at the time it is issued (for example, a promotional grant may carry its own expiration, disclosed when it is granted).

Pro plans and credit packs

• Pro monthly — $20.00 USD/month, includes 300 credits per billing period, billed on a recurring basis until cancelled.
• Pro yearly — $180.00 USD/year, includes 1,200 credits per billing period (equivalent to 100/month, at a discount to the monthly price), billed annually until cancelled.
• Credit packs (one-time, no subscription): 50 credits for $10, 120 credits for $20, 200 credits for $30, or 400 credits for $50. Credit packs are available to Pro subscribers (and account owners); they are not sold to free-tier accounts.
• All prices are in USD and do not include tax. Applicable sales tax is calculated automatically at checkout based on your billing address and added to the charge.
• Payment is processed by Stripe. We never see or store your card number — see the privacy policy.

No refunds

Credits and subscription charges are non-refundable. This applies to one-time credit packs, monthly and yearly Pro subscription charges, and credits already spent. We mean this plainly, and we back it with how failures are actually handled:

• If a generation fails outright — the engine errors out and you get no drawing — we return the credits for it. That is not a refund of money; it is us not charging you for something that did not happen. Credits returned this way go back to your balance, not to your card.
• A generation that produces a drawing you simply do not like is a different case. Those credits are spent. The drawing stays yours, and support can help you get to a better result — but we do not return credits because the output disappointed you.
• Cancelling a Pro subscription stops future renewal; it does not refund the current billing period, and any credits already granted for that period remain usable until they would otherwise expire.
• This policy exists because credits are consumed by real compute cost (AI model calls, conversion processing) at the moment they are spent — not because we are indifferent to a bad outcome. Tell us when something goes wrong; we fix the product. What we do not do is send money back.

4. What you own

You own the drawings, floor plans, DXF/DWG files and other output you create with CADdillo, including drawings drafted by the AI engine from your description. You may use them commercially, including in construction documents, client deliverables and anything you bill for, subject to §5 (AI outputs and no engineering advice) below.

To run the service, you grant us a limited license to store, process and transmit your files and drawing data as needed to provide CADdillo to you — for example, saving a drawing to your account, or sending drawing context to the AI model when you ask it to make a change. We do not use your drawings to train AI models, and we do not sell them. See the privacy policy for the full detail on what is stored, what is not, and for how long.

Public catalog: drawings made on the free tier may be included, without your name or email, in a public template and example catalog on the site. This is on by default. You can opt out at any time by emailing [email protected] from your account address, and we remove your drawings from the catalog within a few days.

5. AI outputs and no engineering advice

This matters more here than almost anywhere else on the site, so it is stated as plainly as we can manage.

• Drawings produced by CADdillo — including anything drafted by the AI engine ("Dillo Bot") — are generated by software and may contain errors: wrong dimensions, missing elements, code citations that do not apply to your jurisdiction, or geometry that looks right and is not.
• Nothing CADdillo produces is stamped, sealed, or reviewed by a licensed architect or engineer. It is not a substitute for one.
• Any reference to a building code, standard or dimension convention in a drawing or on a block/room page is informational context for drafting, not a compliance determination. Code adoption and amendment are local and change over time.
• You are solely responsible for verifying dimensions, clearances and code compliance against the governing standard for your project and jurisdiction, and for obtaining any permits required before anything is built from a CADdillo drawing.

6. Acceptable use

You agree not to:

• Use CADdillo for anything unlawful, or to create content that is unlawful, infringing or fraudulent.
• Scrape, crawl or make automated bulk requests against the site, the app, or the API outside of normal interactive use.
• Reverse engineer, decompile, or attempt to extract the source of the CADdillo editor, converter, or AI drafting engine.
• Resell, sublicense or rebrand access to CADdillo as your own service.
• Create multiple accounts to accumulate more free signup credits or free DWG exports than a single account is meant to receive.

We may suspend or terminate an account that does any of the above, without a refund of any remaining credit balance in the case of clear abuse.

7. Third-party services we rely on

Running CADdillo requires a few third parties, and files or account data pass through them as part of providing the service:

• Cloudflare — hosting, CDN, bot protection, and cookieless web analytics.
• Stripe — payment processing for subscriptions and credit packs. Card data goes directly to Stripe; we never receive it.
• SendGrid — sends sign-in links and account/support email.
• AI model providers — power the Dillo Bot drafting engine. Only the content needed to answer your request (your prompt, plus the drawing context required) is sent, and only when you use the AI features.

Full detail on what each service sees is in the privacy policy.

8. Trademarks

AutoCAD, DWG, TrustedDWG and RealDWG are trademarks of Autodesk, Inc. CADdillo is not affiliated with, endorsed by, or sponsored by Autodesk. References to DWG and DXF describe file format compatibility only.

A file CADdillo writes as DWG may show a notice when opened in AutoCAD stating that it was not created by an Autodesk application. This is normal and expected: it is the same notice AutoCAD shows for any file written by third-party CAD software, and it does not indicate a defect in the file.

The CADdillo name and armadillo logo are our own trademarks. The CAD block library is released separately under its own public-domain dedication — see the license page — but that license does not extend to the CADdillo software, brand, or this website.

9. What we own

The CADdillo software (the editor, converters, AI drafting engine and this website), our templates and patterns, and our trademarks are the property of Quantum Armadillo, LLC. Nothing in these terms transfers ownership of the software to you — you get a right to use it as described here, not a copy of it to keep.

10. DMCA and copyright complaints

If you believe content on CADdillo infringes your copyright, contact [email protected] with a description of the work, the material you believe infringes it, and your contact information. We will investigate and respond.

11. Termination

You may stop using CADdillo and delete your account at any time from the app, or by asking through the contact form. We may suspend or terminate access for violation of these terms, including the acceptable-use rules in §6. Sections that by their nature should survive termination — ownership, no-refunds, disclaimers, limitation of liability — do survive it.

12. Disclaimers and limitation of liability

CADDILLO IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the service will be uninterrupted, error-free, or that AI-generated output will be accurate or complete.

To the maximum extent permitted by law, Quantum Armadillo, LLC's total liability to you for any claim arising from your use of CADdillo is limited to the amount you paid us in the 12 months before the claim arose.

13. Changes to these terms

We may update these terms as the product changes. We will update the "Last updated" date at the top of this page when we do. For a change we consider material, we will make a reasonable effort to notify account holders before it takes effect, the same way we handle material changes to the privacy policy.

14. Governing law

These terms are governed by the laws of the State of Texas, without regard to its conflict of laws principles. Any dispute arising from these terms or your use of CADdillo will be brought in the state or federal courts located in Harris County, Texas, and you consent to jurisdiction there.

15. Contact

Use the contact form, or email [email protected]. A real person reads it.
