Terms of Service

1. Introduction

These Terms of Service (“Terms”) govern your use of Vaquill AI, a legal-AI software tool for US-licensed in-house counsel and legal teams, and, via our API, for businesses that license it (see Section 21), provided by Aralsura Solutions LLP, an India-registered limited liability partnership that operates Vaquill AI (“Aralsura,” “Vaquill AI,” “we,” “our,” or “us”). By creating an account, purchasing a subscription, or otherwise using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

2. UPL & Legal-Advice Disclaimer

Vaquill AI is a software tool for use by licensed lawyers. Vaquill AI is NOT a law firm and does NOT provide legal advice. Vaquill AI does not substitute for the judgment of a qualified lawyer. Communications with Vaquill AI are protected by our Privacy Policy.

You are solely responsible for verifying AI-generated output before using it in any legal matter or court filing. AI may produce inaccurate or fabricated citations (“hallucinations”); every output must be independently verified by a licensed lawyer before it is relied upon or filed. Using the Service does not create an attorney-client relationship between you and Vaquill AI.

3. Eligibility

To create an account and use the Service, you must:

• Be at least 18 years old;
• Be a US-licensed lawyer in good standing, or an employee or agent of a law firm that has authorized your access and whose lawyers are US-licensed;
• Have the legal capacity to enter into a binding contract; and
• Not be barred from using the Service under the laws of the United States or your jurisdiction.

These eligibility requirements apply to the Vaquill application. Accounts that access Vaquill AI only through our API are governed by Section 21 (API Accounts), which permits business and non-lawyer accounts and does not require you to be a lawyer or a law firm.

4. Accounts

4.1 Registration

You agree to provide accurate, current, and complete information during registration and to keep it updated. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us immediately at contact@vaquill.ai of any unauthorized access or security incident.

4.2 One User Per Seat

Each paid seat is for use by a single named user. You may not share credentials, share a seat between multiple lawyers, or allow a third party to use the Service on your behalf.

4.3 Firm Administrators

A firm may designate one or more administrators with authority to manage seats, view firm-level usage, export matter data, and deactivate users. Administrators act on behalf of the firm and bind the firm to these Terms with respect to the firm’s account.

5. Acceptable Use

You agree not to, and not to permit anyone else to:

• Use the Service for the unauthorized practice of law by any non-lawyer;
• Use the Service in any manner prohibited by the rules of professional conduct of any bar to which you are admitted;
• Re-identify or attempt to re-identify any de-identified or anonymized data;
• Reverse engineer, decompile, or attempt to derive the source code or training data of the Service or any underlying model;
• Scrape, crawl, or use automated tools to access the Service other than through our documented APIs;
• Infringe third-party intellectual property, publicity, or privacy rights;
• Upload content containing malware, or transmit content that is unlawful, defamatory, harassing, or obscene;
• Interfere with or disrupt the Service, its infrastructure, or other customers’ use;
• Use the Service to build a competing product or to benchmark it without our prior written consent (for API accounts, this restriction is replaced by the one in Section 21.3).

6. Subscription, Billing & Refunds

6.1 Plans and Fees

The Service is offered on a monthly or annual subscription basis. Fees are described on our pricing page or in an order form. All fees are in US dollars and exclusive of applicable taxes, which you are responsible for paying.

6.2 Free Trial

We may offer a 7-day free trial. If you do not cancel before the trial ends, your subscription will automatically begin and you will be charged the applicable subscription fee.

6.3 Auto-Renewal

Subscriptions automatically renew at the end of each billing cycle at the then-current rate until you cancel. You authorize us (through our PCI-DSS-compliant payment processor for US-dollar billing) to charge your payment method on each renewal.

6.4 Cancellation

You may cancel at any time from your account settings. Cancellation takes effect at the end of your current billing cycle. You will continue to have access through that date.

6.5 Refunds

Fees are non-refundable except as required by applicable law or as expressly stated in a written order form. If we materially reduce the functionality of a feature you paid for, we will offer a pro-rated refund for the unused portion of your current billing cycle.

6.6 Price Changes

We may change subscription prices with at least 30 days’ notice. Price changes take effect at the start of your next billing cycle.

7. AI-Generated Output Disclaimer

Outputs generated by the Service are produced by machine-learning models and may contain errors, omissions, or fabricated citations. Outputs are not legal advice, are not a substitute for independent professional judgment, and must be reviewed by a licensed lawyer before use. You acknowledge your ongoing professional obligations, including:

• ABA Formal Opinion 512 (July 2024) on the ethical use of generative AI by lawyers;
• ABA Model Rule 1.1 and comments 8 on technological competence;
• ABA Model Rule 1.6 on the duty of confidentiality;
• ABA Model Rule 5.3 on responsibilities regarding non-lawyer assistance, which extends to AI tools;
• Parallel rules adopted by your state bar and any applicable court orders or standing orders regarding AI-assisted filings.

You are solely responsible for verifying every citation, quotation, factual assertion, and legal conclusion before incorporating an output into a client matter, pleading, brief, or other work product.

8. Customer Data & Intellectual Property

8.1 Your Content

As between you and Vaquill AI, you retain all right, title, and interest (including intellectual property rights) in the documents, prompts, matter data, and other content you upload or submit to the Service (“Customer Data”) and in outputs generated for you (“Outputs”). Vaquill AI does not claim ownership of Customer Data or Outputs.

8.2 License to Operate the Service

You grant Vaquill AI a limited, worldwide, non-exclusive, royalty-free license to host, process, transmit, and display Customer Data and Outputs solely as necessary to provide, secure, and support the Service for you. This license terminates when you delete the relevant Customer Data or when your account is closed, subject to the retention periods in our Privacy Policy.

8.3 Our Intellectual Property

The Service, including its software, models, user interface, documentation, and trademarks, is owned by Vaquill AI or its licensors and is protected by US and international intellectual property laws. Except for the rights expressly granted in these Terms, no rights are granted to you.

9. No Training on Your Content

Vaquill AI will not use Customer Data or Outputs to train, fine-tune, or improve Vaquill AI’s AI models or the base models of our third-party LLM providers. Our LLM sub-processors operate under zero-data-retention agreements, meaning they do not persist prompts or outputs beyond the time required to return a response. See our Privacy Policy for details.

10. Warranties & Disclaimers

The Service is provided “AS IS” and “AS AVAILABLE,” without warranty of any kind, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising out of course of dealing or usage of trade, except to the extent such disclaimers are not permitted by law.

Without limiting the foregoing, Vaquill AI does not warrant that Outputs will be accurate, complete, current, reliable, or suitable for any particular matter. AI outputs are probabilistic and may contain errors or fabricated citations. You assume all risk associated with your use of Outputs.

11. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUES, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

EACH PARTY’S TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO VAQUILL FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM OR (B) ONE HUNDRED US DOLLARS ($100).

The limitations in this Section apply to the maximum extent permitted by applicable law. Some jurisdictions do not allow the exclusion of certain warranties or limitations on liability, so some of the above limitations may not apply to you.

12. Indemnification

By you. You will defend, indemnify, and hold harmless Vaquill AI and its affiliates, officers, directors, employees, and agents from and against any third-party claim arising out of or relating to (a) your Customer Data, (b) your use of the Service in violation of these Terms or applicable law, or (c) your violation of any third-party right.

By Vaquill AI. Vaquill AI will defend, indemnify, and hold you harmless from and against any third-party claim alleging that the Service, when used in accordance with these Terms, infringes a US patent, copyright, trademark, or trade secret. Vaquill AI’s obligations do not apply to claims arising from Customer Data, Outputs you modify or use outside the Service, or your combination of the Service with any product or service not provided by Vaquill AI.

The indemnified party will (i) promptly notify the indemnifying party of the claim, (ii) give the indemnifying party sole control of defense and settlement (so long as no admission of liability is made without the indemnified party’s consent), and (iii) provide reasonable cooperation at the indemnifying party’s expense.

13. Suspension & Termination

Either party may terminate these Terms for any reason on notice to the other. We may suspend or terminate your access immediately if you materially breach these Terms, if required by law, or if your continued use poses a risk to other customers or the Service.

On termination, (a) your right to use the Service ends, (b) you may export Customer Data for up to 30 days, and (c) Sections 2, 7, 8, 9, 10, 11, 12, 14, 15, 16, 17 and 21 survive.

14. Governing Law & Venue

These Terms are governed by the laws of the State of Delaware, without regard to its conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Subject to Section 15 (Arbitration), the exclusive venue for any dispute not subject to arbitration is the state or federal courts located in Wilmington, Delaware, and each party consents to the personal jurisdiction of those courts.

15. Mandatory Arbitration & Class-Action Waiver

Please read this Section carefully. It affects your legal rights.

Except for claims for injunctive relief related to intellectual property, any dispute, claim, or controversy arising out of or relating to these Terms or the Service (a “Dispute”) will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. Arbitration will be conducted in English in Wilmington, Delaware, or remotely by agreement. Judgment on the award may be entered in any court of competent jurisdiction.

Class-action waiver. You and Vaquill AI each agree to bring Disputes only in an individual capacity and not as a plaintiff or class member in any purported class, collective, or representative proceeding. The arbitrator may not consolidate more than one person’s claims and may not preside over any form of representative or class proceeding.

30-day opt-out. You may opt out of this arbitration agreement by sending a written notice to contact@vaquill.ai with the subject line “Arbitration Opt-Out” within 30 days of first accepting these Terms. Your notice must include your name, the email on your account, and a clear statement that you wish to opt out. Opting out will not affect any other provision of these Terms.

16. DMCA Notice & Takedown

Vaquill AI complies with the Digital Millennium Copyright Act. If you believe content made available through the Service infringes your copyright, send a written notice to our designated agent that includes the six elements required by 17 U.S.C. § 512(c)(3):

• A physical or electronic signature of the owner or authorized agent;
• Identification of the copyrighted work claimed to be infringed;
• Identification of the material that is claimed to be infringing and its location on the Service;
• Your contact information (address, telephone, email);
• A statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; and
• A statement, under penalty of perjury, that the information in the notice is accurate and that you are the owner or authorized to act on the owner’s behalf.

Designated agent: contact@vaquill.ai. If you believe content was removed in error, you may submit a counter-notice to the same address containing the elements required by 17 U.S.C. § 512(g)(3). We may terminate the accounts of repeat infringers.

17. Export Controls & Sanctions

The Service is subject to US export-control laws, including the Export Administration Regulations (EAR) and sanctions administered by the Office of Foreign Assets Control (OFAC). You represent that you are not located in, and will not access the Service from, a country embargoed by the US government, and that you are not listed on any US government list of restricted or denied persons. You will not export, re-export, or transfer the Service in violation of US law.

18. Feedback

If you provide suggestions, feedback, or ideas about the Service, you grant Vaquill AI a perpetual, irrevocable, worldwide, royalty-free license to use them for any purpose, without compensation or attribution. Feedback is provided on an as-is basis.

19. Changes to These Terms

We may update these Terms from time to time. For material changes, we will notify you by email or through an in-product notice at least 30 days before the change takes effect. Your continued use of the Service after the effective date constitutes acceptance of the updated Terms. If you do not agree, stop using the Service and cancel your subscription.

20. Miscellaneous

These Terms, together with our Privacy Policy and any order form, are the entire agreement between you and Vaquill AI regarding the Service and supersede all prior agreements. Where a signed order form or written agreement between you and Aralsura Solutions LLP conflicts with these Terms, that document controls to the extent of the conflict. If any provision is held unenforceable, the remainder will remain in effect. Our failure to enforce any right is not a waiver. You may not assign these Terms without our prior written consent; we may assign them in connection with a merger, acquisition, or sale of assets. Notices to Vaquill AI must be sent to contact@vaquill.ai.

21. API Accounts

This Section governs accounts that access Vaquill AI solely through our application programming interface (the “API”), rather than the Vaquill application. For API accounts, this Section controls over any conflicting provision elsewhere in these Terms.

21.1 Eligibility (non-lawyers permitted)

API accounts are open to businesses and individuals, including companies that are not law firms and users who are not lawyers. The lawyer and law-firm requirements in Section 3 do not apply to API accounts. You represent that you are authorized to enter these Terms on behalf of your organization.

21.2 License

We grant you a non-exclusive, non-transferable, revocable license to call the API and use its responses (“Output”), including within products, tools, and content you provide to your own clients, subject to these Terms and your plan’s limits.

21.3 Permitted and restricted uses

Using the Output to ground, draft, or enrich content and tools for your clients is permitted. You may store Output in a database or index within your own systems, including persistently, where that store exists to power your own end-user product.

Except as expressly permitted in a separate written agreement signed by Aralsura Solutions LLP, you will not:

• systematically extract, bulk-download, scrape, crawl, or otherwise accumulate the corpus, whether through the API or by iterating its endpoints, for any purpose other than powering your own end-user product;
• resell, sublicense, or redistribute the underlying legal data or our compilation as a standalone dataset, database, feed, or API to third parties;
• offer the API, or any service substantially derived from it, to third parties under your own or a third party’s brand;
• use the API or its Output to build, train, or improve a product that competes with the Vaquill AI legal-research, statute-retrieval, or legal-data API services;
• reverse engineer the API, or attempt to derive its source code, models, or training data; or
• exceed or circumvent the rate limits or credit allowance of your plan, including by distributing access across multiple accounts.

For API accounts, this Section replaces the restriction in Section 5 on building a competing product.

21.4 Not legal advice; verification

The API returns legal information, not legal advice, and may be inaccurate or incomplete. You are responsible for independently verifying Output against official sources before it is relied upon, published, or used in any legal matter. Section 2 and Section 7 apply to API Output.

21.5 Fees, credits, and rate limits

API access is provided on the paid plan you select, or on a free, trial, or non-commercial allowance we grant at our discretion, which we may modify or withdraw at any time. Each plan includes a monthly credit allowance and rate limit described at signup or in an order form. Fees are billed in advance and are non-refundable except as required by law, and you may upgrade at any time. Our commitment in Section 9 not to train on your content applies to your API queries and Output.

21.6 US law data, caching, and the open dataset

The statutory, regulatory, and constitutional text returned by the API is US primary law and is in the public domain under the government edicts doctrine (Georgia v. Public.Resource.Org, Inc., 590 U.S. 255 (2020)). We claim no ownership of that text, and nothing in these Terms restricts your use of the public-domain text itself. What is licensed to you, and what Section 21.3 protects, is our structured compilation: the schema, citations, hierarchy, cross-references, metadata, and the assembled corpus.

You may cache and store API responses within your own applications and internal systems, and you may redistribute the public-domain text. You may not, per Section 21.3, resell our bulk structured dataset as a standalone data product, or use the API to build a competing legal-data API or database.

Separately from the paid API, we publish “Open US Law” as a free, downloadable dataset. The public-domain text carries no restriction; our compilation of it is licensed under Creative Commons Attribution 4.0 (CC BY 4.0), and the ingestion scrapers are Apache-2.0. The open dataset is governed by those licenses. The hosted API and MCP server are the paid, rate-limited service governed by these Terms. If you rely on the compilation via the open dataset, attribute it as “Open US Law by Vaquill AI, CC BY 4.0.”

21.7 White-label and reseller access

White-label and reseller access is available only under a separate written agreement signed by Aralsura Solutions LLP. Under such an agreement: every request must be served live by the Vaquill AI API and metered to your account, and you may not serve white-labeled traffic from a cached, extracted, or locally stored copy of the corpus; you remain responsible for your end users’ compliance with these Terms; you will not represent that you compiled, maintain, or own the underlying corpus; and the verification notice in Section 21.4 must be passed through to your end users.

21.8 Effect of termination on stored data

What you may keep depends on how you obtained the data, not on when you stop paying.

Data retrieved through the API. Responses you retrieved and cached in the ordinary course of using the API during a paid term are yours to keep after termination or expiry. You do not have to delete them, and you may continue to display them to your customers. This includes the compilation elements those responses carry, meaning the citations, hierarchy, cross-references and metadata, because cached answers are not usable without them.

Bulk data delivered under a separate agreement. Where we deliver the corpus in bulk rather than call by call, the corpus itself is the deliverable, and permanent retention would let a single period buy it outright. On termination or expiry of a bulk arrangement you will within thirty (30) days delete stored copies of our compilation, meaning the schema, citations, hierarchy, cross-references, metadata and assembled corpus, except for anything you had independently retrieved through the API, the public-domain text itself, anything obtained separately under the Open US Law licenses, and Output already embedded in work product delivered to your clients before termination.

Retention is not a license to redistribute. Section 21.3 continues to apply to anything you keep: you may not resell our compilation as a standalone data product, nor use it to build a competing legal-data API or database. The public-domain text carries no such restriction and never did.

21.9 Attribution

Unless your plan waives it, you will display the credit “Legal data by Vaquill AI”, linked to vaquill.ai, in any product, tool, page or interface of yours where Output is shown to your own end users. One credit per such product is enough: it belongs somewhere a user can reasonably find it, such as a footer, an about page, a data-sources page, or the screen where the legal content appears. It does not have to accompany each individual response. We provide the exact snippet, including a link tagged to your account, in the developer console.

The credit is not required for internal or back-office use where Output is not displayed to anyone outside your organization, for evaluation or testing, or for Output embedded in individual work product you deliver to a client, such as a memo, contract or filing.

The Vaquill AI API Business plan waives this Section, as does any separate written agreement that says so: on those plans you may ship our data under your own brand with no credit. Nothing in this Section grants you any right in our name or marks beyond displaying the credit itself, and nothing in it lets you state or imply that we endorse you or your product.

We may ask where the credit is displayed, and you will tell us. That is the extent of it: this Section gives us no audit right, no inspection right, and no right to access your systems. Access to the API does not depend on the credit, and we will not suspend, throttle or degrade a paid account over one. If a credit is missing we will tell you and give you thirty (30) days to display it; if it is still missing after that, our remedy is to decline to renew your plan at the end of its then-current term.

For accounts that existed on August 30, 2026, this Section takes effect on September 1, 2026.

22. Publicity and Customer Identification

22.1 Customer list

If you hold a paid subscription, you grant Vaquill AI a limited, non-exclusive, royalty-free license to use your organization’s name and logo to identify you as a Vaquill AI customer in a customer list on our website and in sales materials. We will use your name and logo in their unmodified form and in line with any brand guidelines you give us.

22.2 What this does not cover

This license does not permit us to state or imply that you endorse or recommend Vaquill AI, to attribute any quotation, testimonial, case study, review, or performance claim to you or to anyone at your organization, to describe how you use the Service, or to name you in a press release. Each of those needs your separate prior written consent, which you may withhold for any reason. We will not identify accounts that are on a free, trial, evaluation, or non-commercial allowance.

22.3 Opting out

You may opt out at any time, before or after any use, by emailing contact@vaquill.ai with the subject line “Publicity Opt-Out.” You do not need to give a reason. We will remove your name and logo from our website within ten (10) business days and from other materials at the next reasonable opportunity. Opting out will not affect your subscription, your pricing, or any other provision of these Terms.

22.4 Ownership and expiry

You keep all right, title, and interest in your name, logo, and trademarks, and nothing in this Section transfers any ownership or goodwill to us. This license ends automatically when your paid subscription ends, and we will remove your name and logo from our website within thirty (30) days of that date. If the individual who accepted these Terms was not authorized to grant this license on your organization’s behalf, write to us at the address above and we will treat it as an opt-out under Section 22.3.
