Terms of Service

1What Tesseract does

Tesseract creates 3D models from descriptions and images you choose to submit. You can inspect a model, change its available dimensions and details, save it in My Objects, or export a file for your own printer. Where ordering is available, you can choose a material and quantity, request a quote, and pay to have the object printed and shipped. Generating or editing a model does not place a print order.

2Eligibility and your account

You must be at least 18, or the age of majority where you live, to place an order. The iOS app sets up access for your installation using a device-linked identifier and credentials. Protect your device and do not share those credentials. If you use Google sign-in in the web app, protect that account too. Keep your contact and shipping details accurate so we can process and deliver your order.

Device-based access is not a transferable sign-in account. We cannot promise that your library will be recoverable after you lose access to your device or credentials. Export copies of models you want to keep.

3Your prompts, your designs

You keep ownership of the descriptions, photographs, and artwork you submit. To the extent we hold any rights in the model generated from your prompt, we assign them to you on payment, and otherwise grant you a worldwide, royalty-free licence to use, modify, print and sell it. In return you grant us the licence we need to actually run the Service: to process your descriptions and images, send them to our AI provider, generate and render the model, manufacture and ship the part, and keep a record of what was ordered.

You are responsible for having permission to use and reproduce the content you submit, including photographs, logos, text, and drawings.

4Generated output

Models are produced by an AI system. Two things follow, and both matter:

• Output isn't unique to you. Someone submitting a similar description may receive a similar model. We make no claim that any output is original, non-infringing, or protectable.
• Output isn't engineered for a purpose. Dimensions, tolerances, wall thickness and strength are the model's best reading of your description. Check the model, measurements, fit, and intended use before exporting or ordering it. Automated checks do not certify a model as safe.

5What the parts are, and what they aren't

Parts are printed in thermoplastic filament by fused-deposition printing. They are consumer-grade objects. Do not use anything made with Tesseract where failure could cause injury, death or significant loss — including load-bearing structural use, climbing or fall protection, vehicles or aircraft, medical, dental or implantable devices, electrical or gas fittings, firearms or firearm components, cookware, or anything within reach of a child small enough to swallow it. How you use what you print is your responsibility.

6Acceptable use

Don't use the Service to design, order or distribute weapons or weapon components; anything that infringes someone else's intellectual property; anything illegal where you are or where we are; counterfeit goods; tools whose purpose is to defeat a lock or security device you don't own; or anything intended to harm a person or an animal.

Don't work around rate limits, scrape the Service, resell access to it, or use its output to train a competing model. Prompts are screened automatically, and we may refuse, cancel or refund any request.

7Prices, quotes and payment

Check the model, dimensions, material, quantity, delivery address, and total before confirming a print order. Changing a model or order detail can require a new quote. Exporting a file for your own printer does not place an order with our manufacturing partner.

Prices are in US dollars and quoted all-in: printing and shipping are both included in the number you see before you pay. Sales tax, duties and import fees may be added at checkout or charged on delivery depending on where you ship.

A quote covers a specific model, material and quantity, and expires 30 minutes after it's issued. Payment is processed by Stripe — we never see or store your card number. Completing checkout authorises us to charge the quoted amount and to place the manufacturing order on your behalf.

If a price is obviously wrong — a display or calculation error, rather than a price you think is too high — we may cancel and refund in full instead of fulfilling the order.

8Manufacturing and delivery

Parts are manufactured by a third-party print partner and ship directly from their facility. Any lead time shown in the Service is an estimate, not a guarantee; production and carrier delays are not on their own grounds for a refund. Title and risk of loss pass to you when the carrier takes possession. If a shipment goes missing in transit, tell us and we'll chase it with the carrier.

9Cancellations, returns and refunds

Every part is manufactured to your order and your dimensions. Once production starts, an order can't be cancelled and a part can't be returned because you changed your mind, mismeasured, or don't like how the design came out.

We will replace or refund a part that arrives:

• defective — layer separation, warping, incomplete printing or a similar manufacturing fault;
• damaged in transit; or
• materially different from the model you ordered.

Email hello@tesseract.build within 14 days of delivery with your order number and photographs of the problem. We'll choose between a reprint and a refund, and we'll cover return shipping if we need the part back. This sits on top of any consumer-law rights you have that can't be waived by agreement.

10Our intellectual property

The Service itself, including the app, the builder library behind it, the prompts that drive it, the name and the mark, is ours. These Terms give you the right to use it, not to copy it.

11Availability

Tesseract is under active development. Beta features, generation limits, supported devices, and ordering availability may change. We may change, suspend or withdraw features without notice, and we don't promise the Service will be uninterrupted or error-free. Orders already paid for will be fulfilled or refunded. You can manage camera and notification permissions in iOS Settings. Turning off notifications does not cancel a generation or an order.

12Disclaimers

Except where the law says otherwise, the Service and everything produced through it are provided “as is” and “as available”, without warranty of any kind — express or implied — including merchantability, fitness for a particular purpose, non-infringement, dimensional accuracy, or the suitability of any design for any use.

13Limitation of liability

To the fullest extent the law allows, tesseract.build is not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost data or business interruption, arising out of the Service or anything made with it. Our total liability for any claim is capped at the greater of what you paid us in the twelve months before the claim and US $100.

Some places don't permit these limits. Where that's so, they apply as far as they're permitted, and nothing here limits liability for death or personal injury caused by our negligence, or for fraud.

14Indemnity

You'll defend and indemnify us against claims arising from your use of the Service, what you submit to it, and what you do with what you make — including a claim that a design you ordered infringes someone else's rights.

15Termination

You can stop using the Service whenever you like and ask us to delete your account — see the Privacy Policy. We may suspend or end access if you breach these Terms or if we're legally required to. Clauses 3–5 and 9–17 survive termination.

16Governing law and disputes

These Terms are governed by the laws of the State of Delaware, without regard to conflict-of-law rules. Before filing anything, email hello@tesseract.build and give us 30 days to put it right — most problems are a reprint. If that doesn't work, disputes go to the state and federal courts located in Delaware, and we each consent to that jurisdiction.

17Changes to these Terms

We may update these Terms. If a change materially affects your rights, we'll say so here and update the date at the top; continuing to use the Service after that means you accept it. The Terms that apply to an order are the ones in force when you placed it.
