3.1 Service Description

TauCAD is an AI-assisted computer-aided design (CAD) software service. The Service enables users to create, edit, convert, and export 3D designs through various tools and features, which may include AI-powered assistance, code-based modeling, file format conversion, and integrations with third-party platforms. We may also offer developer tools, APIs, and software packages for programmatic access to certain Service functionality.

To use our Service, you must be at least 18 years old or the age of legal majority in your jurisdiction, whichever is greater.

3.2 Subscription Plans

Many features of our Service are available for free without a Subscription. For access to additional features, increased usage limits, and premium capabilities, we offer paid Subscriptions:

  • Monthly Subscriptions: Billed on a recurring monthly basis
  • Annual Subscriptions: Billed annually with a discount compared to monthly rates
  • Usage Credits: Pay-per-use credits for AI features and API calls, purchased separately or included in subscription tiers

Your Subscription will automatically renew at the end of each billing period unless you cancel before the renewal date. You authorize us to charge your payment method for the Subscription fee at the beginning of each billing period. Prices are subject to change with at least 30 days' notice.

3.3 Cancellation & Refunds

You may cancel your Subscription at any time through your account settings or by contacting us at support@tau.new. Upon cancellation, access continues until the end of your current billing period. No refunds are provided for unused portions of the billing period, except as required by applicable law (see Section 15 for consumer rights) or at our sole discretion for billing errors.

3.4 Taxes & Payment

All fees are exclusive of applicable taxes, unless otherwise stated. You are responsible for all applicable taxes (including VAT, GST, and sales taxes) based on your location. If your payment method fails, we may suspend your access to paid features until payment is collected. Usage credits expire 1 year from the date of purchase, unless otherwise specified.

  • Providing accurate, current, and complete information
  • Maintaining the confidentiality of your password and account

6. Intellectual Property & Open Source

6.1 Our Intellectual Property

All content provided by TauCAD Limited, including the Service, website, text, graphics, logos, and software, is the property of TauCAD Limited or its content suppliers and is protected by international intellectual property laws. Our trademarks and trade dress may not be used without our prior written consent.

We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your internal business purposes or personal use. This license does not include the right to modify, copy, resell, sublicense, reverse engineer, or distribute the Service, except as permitted by applicable open-source licenses.

6.2 Open Source

TauCAD is built on open-source software. The source code is publicly available at https://github.com/taucad/tau.

TauCAD is dual-licensed:

  • MIT License: Applies to all components except the OpenSCAD kernel.
  • GPL-2.0-or-later: Applies when using the OpenSCAD kernel due to the openscad-wasm-prebuilt dependency.

Nothing in these Terms restricts your rights under the applicable open-source licenses. The following elements remain proprietary: the hosted SaaS infrastructure, API rate limits and subscription tiers, your User Data, the TauCAD name and trademarks, and any content we create that is not part of the open-source codebase.

6.3 Your Designs

CAD designs, models, and other creative works you create using TauCAD are your intellectual property. Your use of TauCAD does not create any obligation for you to license your designs under any open-source license.

6.4 Feedback & Contributions

You grant us a perpetual, irrevocable, royalty-free license to use any feedback, comments, or suggestions you provide. If you contribute to the TauCAD open-source project, your contributions will be licensed under the same license as the project.

7. Disclaimers & Liability

Summary: The Service is provided "as is" without warranties. Our liability is limited to the amount you paid us in the 12 months prior to any claim, or NZD $100, whichever is greater.

7.1 Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

THE SERVICE IS NOT INTENDED TO PROVIDE PROFESSIONAL ENGINEERING, MANUFACTURING, OR SAFETY-CRITICAL ADVICE. CAD DESIGNS CREATED USING THE SERVICE SHOULD BE REVIEWED BY QUALIFIED PROFESSIONALS BEFORE USE IN PRODUCTION, MANUFACTURING, OR ANY APPLICATION WHERE FAILURE COULD RESULT IN HARM.

7.2 Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TAUCAD LIMITED SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES.

OUR TOTAL LIABILITY FOR ANY CLAIMS ARISING FROM THESE TERMS OR YOUR USE OF THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS PRIOR TO THE CLAIM, OR (B) ONE HUNDRED NEW ZEALAND DOLLARS (NZD $100).

Some jurisdictions do not allow limitations on implied warranties or liability for incidental or consequential damages, so the above limitations may not apply to you.

7.3 Indemnification

8. Legal Terms

8.1 Governing Law

These Terms shall be governed by and construed in accordance with the laws of New Zealand, without regard to its conflict of law provisions.

8.2 Dispute Resolution

Before initiating legal proceedings, you agree to contact us at legal@tau.new to attempt to resolve the dispute informally. We will respond within 30 days.

Any disputes will be resolved in the courts of Auckland, New Zealand, except where local consumer protection laws require disputes to be heard in your place of residence (see Section 15 for consumer rights).

8.3 Class Action Waiver

To the maximum extent permitted by applicable law, you agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. You waive any right to participate in a class action lawsuit or class-wide arbitration against TauCAD Limited.

Jurisdictional limitations: This waiver does not apply, and you retain your full statutory rights, where prohibited by law. In particular:

  • EU/EEA consumers: This waiver does not affect your right to participate in collective redress mechanisms under EU law.
  • UK consumers: This waiver does not limit your rights under the Consumer Rights Act 2015 or collective proceedings before the Competition Appeal Tribunal.
  • Australian consumers: This waiver does not exclude or limit any rights under Australian Consumer Law.
  • New Zealand consumers: This waiver does not affect your rights under the Consumer Guarantees Act 1993.
  • Canadian consumers: This waiver may not apply in provinces where class action waivers are prohibited for consumer contracts.

If the class action waiver is found unenforceable in your jurisdiction, only that portion shall be severed; the remainder of these Terms remains in full force and effect. For additional information about your consumer rights, see Section 15.

8.4 Termination

We reserve the right to suspend or terminate your access to our Service at our sole discretion, with or without notice, for conduct that we believe violates these Terms or is harmful to other users, us, or third parties. Upon termination:

8.5 General Provisions

These Terms, including our Privacy Policy and any other agreements referenced herein, constitute the entire agreement between you and TauCAD Limited regarding your use of our Service. The failure of TauCAD Limited to enforce any right or provision will not be deemed a waiver. If any provision is found invalid or unenforceable, the remaining provisions will remain in full force. These Terms may not be transferred or assigned by you without our prior written consent, but may be assigned by us without restriction. All provisions which by their nature should survive termination shall survive.

9. Additional Terms
