Terms & Conditions

1. The service

The Drafter Toolbox provides preliminary engineering calculators, references, generators, and AI-assisted tools (together, the “Service”) intended to speed up routine mechanical engineering work. The Service is offered without requiring an account; an anonymous session identifier is used to keep your work and history together during a visit.

2. Engineering disclaimer: no reliance

The Service is a preliminary, convenience aid, not a substitute for professional engineering judgment. Every calculator, estimate, drawing review, and AI response is provided for reference only and may contain errors, simplifying assumptions, or results that do not apply to your specific application.

• You are solely responsible for independently verifying every result against your governing specifications, applicable codes and standards (e.g., ASME, ISO, AISC), and sound engineering practice before relying on it.
• Results must be reviewed and approved by a qualified engineer (and, where required by law or your organization, a licensed Professional Engineer) before use in any design, analysis, procurement, manufacturing, or safety-related decision.
• Do not use the Service as the basis for design release, regulatory submission, or any decision affecting human safety without full independent validation.

3. Your content and submissions

You may enter values, upload drawings or files, and send messages to the AI tools (“Your Content”). You retain all ownership of Your Content. You grant Drafter Inc. a limited license to process, transmit, and store Your Content solely to operate and improve the Service, including sending it to the third-party AI providers described in our Privacy Policy.

Only submit information you are authorized to share. Many of our users work under employer confidentiality obligations, NDAs, or government export controls. You represent that you have the right to submit Your Content and that doing so does not violate any confidentiality agreement, your employer’s policies, or applicable law, including U.S. export-control regimes such as ITAR and the EAR. Do not upload classified, controlled, or third-party confidential material unless you are permitted to disclose it to a cloud service and its AI subprocessors.

4. Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of any third-party right;
• Attempt to disrupt, overload, reverse-engineer, or gain unauthorized access to the Service or its infrastructure;
• Scrape, resell, or redistribute the Service or its outputs as a competing product; or
• Upload malware or content that infringes intellectual property.

5. No warranty

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that any result will be correct or suitable for your purpose.

6. Limitation of liability

To the maximum extent permitted by law, Drafter Inc. and its officers, employees, and suppliers will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, goodwill, or for costs of procurement of substitute goods or services, or for any damages arising from design errors, rework, scrap, downtime, or product failures, arising out of or relating to your use of the Service, even if advised of the possibility of such damages. Our total aggregate liability for all claims relating to the Service will not exceed one hundred U.S. dollars (US$100).

7. Indemnification

You agree to indemnify and hold harmless Drafter Inc. from any claims, damages, or expenses (including reasonable legal fees) arising from Your Content, your use of the Service, or your violation of these Terms, including any claim that your submissions breached a confidentiality, export-control, or third-party obligation.

8. Intellectual property

The Service, including its software, design, text, and branding (excluding Your Content), is owned by Drafter Inc. and protected by intellectual-property laws. These Terms grant you no rights in our marks or software beyond using the Service as intended.

9. Third-party services

The Service relies on third-party infrastructure and AI model providers to function. Your use may be subject to those providers’ terms. See our Privacy Policy for details on how data is processed and shared.

10. Changes

We may update the Service or these Terms from time to time. Material changes will be reflected by the “Last updated” date above. Continued use after a change constitutes acceptance of the revised Terms.

11. Governing law

These Terms are governed by the laws of the State of Delaware and the United States, without regard to conflict-of-laws rules. Any dispute will be resolved in the state or federal courts located in Delaware.
