Terms of Service

Last updated: May 29, 2026
Terms of Service Privacy Cookies Acceptable Use

These Terms of Service ("Terms") govern your access to and use of the NOVA-3 platform, the interactive playground/demo, the developer API, the Module Library, and any related websites, software, and services (collectively, the "Service") made available by QAI Labs Ltd., a Delaware corporation with its principal office in Sugar Land, Texas, USA ("QAI Labs," "we," "us," or "our").

Please read these Terms carefully. They include important provisions regarding the research-use-only nature of the Service, disclaimers of warranties, and limitations of liability. By accessing or using the Service, you agree to be bound by these Terms.


1. Acceptance of Terms

By accessing, registering for, or using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy and Acceptable Use Policy, which are incorporated by reference. If you do not agree to these Terms, you may not access or use the Service.

If you are accessing or using the Service on behalf of an organization (a "Customer"), you represent and warrant that you are authorized to bind that organization to these Terms, and references to "you" include both you and that organization.

We may make the Service available under a separate, individually negotiated Master Services Agreement ("MSA") or other written agreement signed by QAI Labs. Where such an agreement exists and conflicts with these Terms, the signed agreement controls for that Customer.


2. Who May Use the Service

  • You must be at least 18 years old to use the Service.
  • The Service is intended for professional and business use by professionals at pharmaceutical, biotechnology, and research organizations, and by qualified researchers. It is not intended for personal, household, or consumer use.
  • You must have the legal authority to enter into these Terms, and, if acting for an organization, the authority to bind that organization.
  • You agree to comply with all applicable laws and regulations in connection with your use of the Service.

3. Description of the Service

NOVA-3 is a computer-aided design platform for multi-specific antibodies. The Service may include, without limitation:

  • In-silico antibody design and engineering tools;
  • Candidate ranking and scoring;
  • Structure prediction, which relies on third-party computational services;
  • A Module Library of reusable components and building blocks;
  • Cryptographic "Evidence Bundles" intended to support reproducibility and provenance of computational results;
  • An interactive playground/demo; and
  • A developer API.

The Service, or portions of it, may be offered on a beta, preview, or evaluation basis. Beta features are provided "as-is," may be changed or discontinued at any time, may be less reliable than generally available features, and may be subject to additional terms presented at the time of access.

We may modify, enhance, suspend, or discontinue all or any part of the Service at any time. We will use commercially reasonable efforts to provide notice of material changes that adversely affect paid features.


4. Accounts and Registration

To access certain features, you must register for an account and provide accurate, current, and complete information. You agree to keep your account information up to date.

You are responsible for:

  • Maintaining the confidentiality of your account credentials and API keys;
  • All activity that occurs under your account; and
  • Promptly notifying us at security@qailabs.co of any unauthorized use or suspected security breach.

We may suspend or terminate accounts that contain false information or are used in violation of these Terms.


5. Subscriptions, Fees, and Usage-Based Billing

  • Certain features may be offered free of charge, on a beta basis, or for evaluation. Other features require a paid subscription or are billed on a usage-based basis (for example, based on API calls, compute consumption, or volume of designs).
  • Pricing, billing frequency, and applicable usage metrics are set out in the applicable order form, online checkout, or our pricing page, as updated from time to time.
  • Unless otherwise stated in an order form or signed agreement, fees are non-refundable, are exclusive of taxes, and you are responsible for all applicable taxes (other than taxes on our net income).
  • We may change pricing for going-forward periods. Price changes do not affect a paid subscription term already in effect unless otherwise agreed.
  • Late or failed payments may result in suspension of the Service after reasonable notice.

6. Customer Content and Data

6.1 Your Content

"Customer Content" means the data, antibody sequences, structures, parameters, files, and other materials you submit to or through the Service. As between you and QAI Labs, you retain all ownership rights in your Customer Content. You represent and warrant that you have all rights necessary to submit Customer Content and to grant the license below, and that your Customer Content does not infringe or violate any third-party rights or applicable law.

6.2 License to QAI Labs

You grant QAI Labs a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, display, and otherwise use Customer Content solely as necessary to provide, secure, maintain, and improve the Service and to comply with law. Where Customer Content includes personal data, our processing is described in our Privacy Policy and, for enterprise Customers, may be governed by a Data Processing Agreement ("DPA").

6.3 Our Intellectual Property

The Service — including the NOVA-3 platform, all underlying software, models, algorithms, the Module Library, user interfaces, documentation, and all related intellectual property — is and remains the exclusive property of QAI Labs and its licensors. Except for the limited rights expressly granted in these Terms, no rights are granted to you, by implication or otherwise. All rights not expressly granted are reserved.

6.4 Outputs

"Outputs" means the predictions, rankings, designs, structures, scores, and Evidence Bundles generated by the Service from your Customer Content. Subject to your compliance with these Terms and payment of applicable fees, QAI Labs grants you a non-exclusive, worldwide license to use Outputs for your internal research purposes. Outputs are subject to the research-use-only and no-medical-use restrictions in Section 8 and the Acceptable Use Policy. You are responsible for evaluating, validating, and verifying Outputs before relying on them.

6.5 Feedback

If you provide suggestions, ideas, or other feedback about the Service ("Feedback"), you grant QAI Labs a perpetual, irrevocable, worldwide, royalty-free license to use and incorporate that Feedback for any purpose without restriction or compensation to you.


7. Acceptable Use

Your use of the Service must comply with our Acceptable Use Policy ("AUP"), which is incorporated into these Terms by reference. The AUP includes important biosecurity and dual-use restrictions and prohibitions on unlawful, harmful, or infringing use. Violation of the AUP is a material breach of these Terms and may result in immediate suspension or termination.


8. Research-Use-Only — No Medical Use

THE SERVICE AND ALL OUTPUTS ARE PROVIDED FOR RESEARCH AND INFORMATIONAL PURPOSES ONLY.

  • Outputs are computational predictions and are inherently uncertain. They require independent experimental validation before any reliance.
  • Outputs are NOT medical advice and are NOT intended or approved for clinical diagnosis, treatment, prevention, or any decision affecting patient care.
  • The Service is not a medical device and has not been cleared or approved by any regulatory authority for clinical use.
  • You are solely responsible for determining whether and how to use Outputs, for conducting appropriate experimental validation, and for compliance with all laws, regulations, and ethical and institutional requirements applicable to your research.

You agree not to use the Service or Outputs in any manner that would require regulatory clearance or approval that has not been obtained.


9. Third-Party Services

The Service relies on and integrates with third-party services, including structure-prediction and other computational providers and cloud hosting and infrastructure providers. These third-party services are provided by their respective providers and may be subject to their own terms. QAI Labs does not control and is not responsible for the performance, availability, accuracy, or acts or omissions of third-party services. Your use of the Service may be affected by the availability of such third-party services.


10. Warranty Disclaimer

THE SERVICE, INCLUDING ALL OUTPUTS, MODELS, THE MODULE LIBRARY, EVIDENCE BUNDLES, THE PLAYGROUND, THE API, AND ANY BETA FEATURES, IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TO THE MAXIMUM EXTENT PERMITTED BY LAW, QAI LABS AND ITS LICENSORS AND SUPPLIERS DISCLAIM ALL WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE.

QAI LABS DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY OUTPUT WILL BE ACCURATE, COMPLETE, RELIABLE, OR SCIENTIFICALLY VALID. ALL OUTPUTS ARE COMPUTATIONAL PREDICTIONS THAT REQUIRE INDEPENDENT EXPERIMENTAL VALIDATION AND ARE NOT MEDICAL ADVICE.


11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

(A) IN NO EVENT WILL QAI LABS OR ITS AFFILIATES, LICENSORS, OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, BUSINESS, GOODWILL, OR RESEARCH RESULTS, OR FOR THE COST OF SUBSTITUTE SERVICES, ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, EVEN IF QAI LABS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

(B) QAI LABS' TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (I) THE AMOUNTS YOU PAID TO QAI LABS FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (II) ONE HUNDRED U.S. DOLLARS (US$100).

(C) FOR FREE, BETA, OR EVALUATION FEATURES, QAI LABS' TOTAL AGGREGATE LIABILITY WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US$100).

THE LIMITATIONS IN THIS SECTION APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN EXCLUSIONS OR LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.


12. Indemnification

You agree to defend, indemnify, and hold harmless QAI Labs and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your Customer Content; (b) your use of the Service or Outputs, including any experimental, research, clinical, or commercial decisions you make; (c) your violation of these Terms, the AUP, or applicable law; or (d) your violation of any third-party rights.


13. Suspension and Termination

We may suspend or terminate your access to the Service, in whole or in part, immediately and without liability, if: (a) you breach these Terms or the AUP; (b) your use poses a security, legal, biosecurity, or reputational risk; (c) required by law or by a third-party provider; or (d) you fail to pay applicable fees.

You may stop using the Service at any time. Upon termination, your right to access the Service ceases. Sections that by their nature should survive termination (including Sections 6.3, 6.5, 8, 10, 11, 12, 14, and 15) will survive. We will make Customer Content available for export for a reasonable period following termination as described in our documentation or applicable order, after which we may delete it in accordance with our retention practices.


14. Export Controls and Sanctions Compliance

The Service and related technology may be subject to U.S. and other export control and economic sanctions laws and regulations. You represent and warrant that you and your end users are not: (a) located in, organized under the laws of, or ordinarily resident in any country or territory subject to comprehensive sanctions; or (b) identified on any government restricted-party or denied-party list. You agree not to access, use, export, re-export, or transfer the Service or Outputs in violation of applicable export control and sanctions laws, and not to use the Service for any prohibited end use.


15. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the State of Delaware, USA, without regard to its conflict-of-laws principles. The U.N. Convention on Contracts for the International Sale of Goods does not apply.

The parties will first attempt to resolve any dispute informally by contacting legal@qailabs.co. Subject to any separate signed agreement, you agree that the state and federal courts located in Delaware will have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the Service, and you consent to personal jurisdiction and venue in those courts. Each party waives any objection to such jurisdiction and venue.


16. Changes to the Service and to These Terms

We may update these Terms from time to time. If we make material changes, we will provide notice by posting the updated Terms on the website with a new "Last updated" date and, where appropriate, by other reasonable means. Changes are effective when posted unless otherwise stated. Your continued use of the Service after changes become effective constitutes acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Service.


17. Miscellaneous

  • Entire Agreement. These Terms, together with the Privacy Policy, Acceptable Use Policy, and any applicable order form or signed agreement, constitute the entire agreement between you and QAI Labs regarding the Service and supersede all prior agreements on that subject.
  • Severability. If any provision is held unenforceable, the remaining provisions will remain in full force and effect, and the unenforceable provision will be modified to the minimum extent necessary.
  • Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets.
  • No Waiver. Our failure to enforce any provision is not a waiver of our right to do so later.
  • Relationship. The parties are independent contractors. These Terms do not create any partnership, joint venture, agency, or employment relationship.
  • Notices. We may provide notices to you via the Service, email, or posting on the website. You may provide notices to us at legal@qailabs.co.
  • Force Majeure. Neither party is liable for delays or failures caused by events beyond its reasonable control.
