Lucio Terms of Use
These Terms of Use apply to customers contracting with Zenlegal Technology Private Limited (India) or Lucio Inc (outside India, other than the United States).
We built Lucio for legal professionals, and these Terms are written with that in mind. They set out what you can expect from us, what we ask of you, and how we will work through things together if something goes wrong. Your data stays yours, your Output belongs to you, and we never use your data to train AI models. In return, we ask that you use Lucio responsibly and within the scope of your subscription.
1. Agreement to Terms
1.1 Who these Terms are between. These Terms of Use ("Terms") form a binding agreement between you ("User" or "Customer") and the Lucio contracting entity identified in Section 1.2 ("Zenlegal" or "Lucio"). Lucio provides the Lucio Products, which include the Lucio Word and Outlook Add-ins, and the web application hosted on www.lucioai.com (together, the "Products" or "Platform"). In these Terms, "we", "us" and "our" refer to Lucio, and "you" and "your" refer to the Customer, and each of us is a "party".
1.2 Your contracting entity. The Lucio entity you contract with depends on where you are located:
If you are located in India, you contract with Zenlegal Technology Private Limited.
If you are located outside India (other than the United States), you contract with Lucio Inc.
Zenlegal Technology Private Limited and Lucio Inc are together the "Lucio Group".
1.3 Who can use the Products. You may be an individual legal practitioner, or a law firm, partnership, chambers, company or other organisation. If you accept these Terms on behalf of an organisation, you confirm that you are authorised to bind it, and "Customer" then means that organisation and its authorised users. You must be at least 18 years old and legally capable of entering into a binding contract.
1.4 Accepting these Terms. By accessing or using the Products and their associated services, you confirm that you have read, understood and agree to these Terms. If you do not agree, please stop using the Products.
1.5 Documents that form part of these Terms. Your use of the Products is also governed by our Privacy Policy, Data Processing Agreement and Technical and Organizational Measures, as applicable, each of which is incorporated into these Terms by reference. Together, they explain how we collect, process, store and protect personal data in line with applicable laws and regulations, and they form part of our commitment to you. By using the Products, you accept these documents. If you disagree with any part of them, please stop using the Products.
1.6 Customers in the United States. If you are located in the United States, these Terms do not apply to you. Your access to and use of the Products is instead governed exclusively by the Lucio Platform Terms of Use (USA) at https://www.lucioai.com/policy/lucio-platform-terms-of-use-usa.
1.7 Bespoke Terms. If your requirements call for it, for example a larger enterprise deployment, you may ask us for a separate written agreement covering the Products (or any part of them). Any such agreement that is signed by an authorised signatory of a member of the Lucio Group prevails over these Terms to the extent of any conflict or inconsistency, for as long as it remains in force. Routine communications do not constitute such an agreement. Routine Communications include invoices, emails, chat or messaging exchanges, proposals, quotes, presentations, product documentation, marketing materials, and any statements made by Lucio’s sales, customer success or support teams. Order forms incorporate these terms by reference but do not override them unless they expressly say so and are signed as described above. This gives both of us certainty about exactly what has been agreed.
2. The Services
2.1 What we provide. Lucio is a suite of artificial intelligence powered Products that provide document analysis functionality, made available to you on a subscription basis. The features and functionality available to you depend on the subscription plan you have chosen.
2.2 How AI Output works. The Products use generative artificial intelligence. Because this technology is probabilistic, and dependent on the quality of documents uploaded, online literature, and your prompts themselves, the outputs generated by the Products ("Output") may sometimes be inaccurate, incomplete or not suited to your particular matter, and may not be unique to you. We are transparent about this so that you can use Lucio with confidence and in the right way.
2.3 Professional review. Lucio is designed to support, not replace, your professional judgment. You are responsible for having all Output reviewed and verified by a suitably qualified professional before relying on it. The Products do not provide legal advice, and your use of them does not create a lawyer-client relationship between you and Lucio.
3. Using the Products
3.1 Your licence. We grant you a limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to access and use the Products solely for your own internal professional purposes, within the number of authorised users and the limits set out in your order form/invoice (as applicable). Where you use the Products in connection with the practice of law or the provision of legal services, you remain solely responsible for complying with all applicable rules of professional conduct, bar or regulatory requirements, client confidentiality obligations and duties of competence. These remain your professional obligations, and Lucio does not assume, and is not responsible for, any of them.
3.2 Prohibited actions. To keep the Products secure, reliable and fair for every customer, you agree that you will not:
(a) copy, reverse engineer, decompile, disassemble, or attempt to derive the source code of the Products;
(b) resell the Products or their associated services, share login credentials within or outside your organization, or allow unauthorised access;
(c) use the Products for any unlawful, illegal or unethical purpose, or upload data that violates applicable laws or third-party rights;
(d) rely on any Output as a substitute for the independent professional judgment of a qualified lawyer, or present Output to any person as legal advice without appropriate professional review;
(e) use the Products to engage in the unauthorised practice of law, or in any high-risk or safety-critical use without qualified human oversight;
(f) use, permit or facilitate any third party to use, the Products or any Output to: (i) develop, train, fine-tune or improve any product, service, or artificial intelligence or machine learning model; (ii) benchmark, evaluate or test the performance, functionality or output quality of the Products against any other product or service, for any purpose whatsoever, including academic research or journalism; or (iii) publish, distribute or disclose to any third party the results of any activity described in (i) or (ii); in each case whether performed directly or through a third party, without Lucio's prior written consent;
(g) scrape, crawl or use automated means to use the Products or extract data from them, or circumvent any usage limit, rate limit or security measure; or
(h) submit to the Products any personal data, confidential information or material of a third party without having all necessary rights, consents and authority to do so.
If you would like to do anything described in paragraph (f), please write to us. We are open to discussing it and will consider your request in good faith.
3.3 Fair usage. Your subscription is subject to fair and reasonable usage, which helps us deliver consistent performance to all customers. Lucio may set, monitor and enforce fair usage. Usage that is not fair includes, without limitation, includes the Prohibited Actions in Section 3.2, irrational, malicious or excessive usage, and non-human usage (such as automation or bots) that disrupts Product performance.
3.4 Misuse. If you misuse the Products or breach these Terms, Lucio may:
(a) immediately suspend or terminate your access to the Products;
(b) charge penalties, including additional fees for unauthorised usage; and
(c) pursue legal remedies, where applicable.
4. Shared Responsibilities
Keeping your account and your work secure is a shared effort. We protect the Platform (see Section 7), and we ask you to do the following on your side.
4.1 Account security. You are responsible for keeping your login credentials confidential. Any activity carried out through your account will be treated as authorised by the account holder.
4.2 Compliance. You will comply with all applicable laws, professional standards, regulations and your own internal organizational policies when using the Products.
4.3 Incident reporting. You will promptly tell us about any unauthorised use of, or security breach affecting, your account, so that we can help you act on it quickly.
5. Fees and Payment
We aim to keep billing simple and predictable. The following applies to your subscription:
5.1 Usage limits. If we have notified you of usage or user limits, usage above those limits will be charged at the applicable rates.
5.2 Payment timelines. Payments are due within the timelines specified in your order form or invoice. Paying on time helps you avoid late payment charges or suspension of the service.
5.3 Taxes. Fees are exclusive of taxes. You are responsible for all applicable taxes, duties and withholdings, other than taxes on Lucio's income, which Lucio bears.
5.4 Refunds. All fees are non-refundable, including pre-paid fees for any unused portion of a subscription term, except where these Terms expressly provide for a refund (see Section 11.3(d)).
5.5 Renewal. Subscriptions renew automatically for successive terms unless cancelled before the renewal date, so your access continues without interruption.
6. Intellectual Property
6.1 What belongs to you. As between you and Lucio, and to the extent permitted by law, you retain all rights in the inputs you submit to the Products ("Inputs") and you own the Output generated for you. Lucio assigns to you any rights it may have in that Output. Please note that Output may not be eligible for copyright or similar protection to the extent it is generated without sufficient human authorship, and that similar or identical Output may be generated for other customers.
6.2 What belongs to Lucio. All intellectual property in the Products, including the software, design, methodologies and features, remains the exclusive property of Lucio and its licensors. No rights are granted to you other than the limited licence expressly set out in these Terms.
6.3 Feedback. We value your feedback. If you share feedback or suggestions about the Products, you grant Lucio a perpetual, irrevocable, royalty-free licence to use that feedback, including to improve the Products for you and other customers.
7. Your Data, Privacy and Security
We understand that legal work is confidential by nature. These commitments are central to how we operate.
7.1 Your data is yours. All data input into and output by the Products by you ("Customer Data") remains the sole property of you or your organisation.
7.2 We act on your instructions. Lucio acts as a data processor and processes Customer Data solely on your instructions, as necessary to provide the services, and in compliance with applicable data protection laws.
7.3 Security. Lucio uses industry-standard security measures to protect Customer Data from unauthorised access, loss or misuse. For your part, you remain responsible for ensuring that your use of the Products complies with applicable privacy laws.
7.4 No training on your data. Customer Data will not be used to train or enhance AI models, or for the benefit of any third party, unless you have explicitly authorised it.
8. Limitation of Liability
8.1 Mutual exclusion of indirect losses. To the maximum extent permitted by applicable law, and except for liability that by law cannot be excluded, neither you nor Lucio will be liable to the other for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, goodwill, business or data, arising out of or relating to these Terms or the Products. This protection applies equally to both parties.
8.2 Lucio's liability cap. To the maximum extent permitted by applicable law, Lucio's total aggregate liability arising out of or relating to these Terms or the Products will not exceed the total subscription fees you paid to Lucio in the twelve (12) months immediately preceding the event giving rise to the claim. This limit applies in the aggregate across you and your affiliates. This cap is directly linked to the value of your subscription and keeps Lucio's pricing accessible to practitioners and firms of every size.
9. Disclaimers and No Legal Advice
We want you to have a clear picture of what Lucio is, and what it is not.
9.1 As-is basis. To the maximum extent permitted by law, the Products and all Output are provided on an "AS IS" basis, without warranty of any kind, whether express, implied or statutory. Lucio disclaims any warranty or assurance as to the accuracy of the Products or Output.
9.2 Not legal advice. The Products and Output do not constitute, and must not be construed, interpreted or relied on as, legal advice, counsel, opinion or recommendations. You agree not to use the Products as a substitute for legal, commercial or contractual advice from qualified professionals. Your use of the Products does not create a lawyer-client relationship between you and Lucio.
10. Indemnification
You control how the Products and Output are used in your practice, and so you are responsible for claims that arise from that use. Accordingly, you will defend, indemnify and hold harmless Lucio, its affiliates, and their respective officers, employees and agents from and against any third-party claims, liabilities, damages, losses and costs (including reasonable legal fees) arising out of or relating to:
(a) your use of the Products or Output in breach of these Terms or applicable law;
(b) the Customer Data or Inputs you submit;
(c) your violation of any third-party right; and
(d) any claim brought by your own clients or any other person arising from your use of, or reliance on, the Products or Output.
11. Term, Suspension and Termination
11.1 Your right to terminate. You may terminate your subscription at any time by giving written notice to help@lucioai.com. Termination does not entitle you to a refund of pre-paid fees.
11.2 Suspension. Lucio may suspend your access to all or part of the Products, with notice where reasonably practicable, if:
(a) you breach these Terms, the acceptable use provisions or the fair usage limits;
(b) there is a security risk to, or an attack on, the Products;
(c) any fee is overdue;
(d) suspension is required by law; or
(e) a third-party provider needed to deliver the Products suspends or terminates access.
Suspension is a protective step, not a termination. Where the cause is curable, Lucio will restore your access once it has been cured. Lucio will have no liability or forego fee otherwise payable, for any suspension made in accordance with these Terms.
11.3 Lucio's right to terminate. Lucio may terminate your access:
(a) for breach of these Terms;
(b) for non-payment of fees;
(c) if you engage in Prohibited Actions; or
(d) for convenience, in which case Lucio will refund any pre-paid fees for the unused portion of the then-current term, so that you do not pay for service you will not receive.
11.4 What happens on termination. On termination, your access to the Products will end and you must stop all use of the Products. You must settle any outstanding payments at the earliest. Termination does not affect any rights or obligations of either party that accrued before termination. Following termination, we will delete Customer Data ordinarily within 30 days, except where retention is required by law or for the establishment or defence of legal claims. You may export your data yourself before termination, and you may also request deletion during your subscription.
11.5 Survival. The following provisions survive termination or expiry of these Terms: Sections 3.4 (Misuse), 5 (Fees and Payment, as to accrued amounts), 6 (Intellectual Property), 7 (Your Data, Privacy and Security), 8 (Limitation of Liability), 9 (Disclaimers and No Legal Advice), 10 (Indemnification), 11.4 (What happens on termination), 11.5 (Survival), 12 (Governing Law and Dispute Resolution) and 14 (General), together with any provision that by its nature should survive. This means your ownership of your data and Output, and Lucio's commitments on privacy and data use, continue after our relationship ends.
12. Governing Law and Dispute Resolution
12.1 Governing law and courts. These Terms are governed by the laws of India. Subject to Section 12.2, the courts in Bengaluru, India have exclusive jurisdiction over any dispute arising out of or relating to these Terms.
12.2 Resolving disputes. If a dispute arises, both parties will first try in good faith to resolve it informally. If it is not resolved informally, either party may take it to the courts referred to in Section 12.1 or, where both parties agree, refer it to binding arbitration. Nothing in this Section prevents either party from seeking urgent interim relief from those courts.
13. Changes to these Terms
Lucio may revise these Terms, the Privacy Policy, the Data Processing Agreement and the Technical and Organizational Measures from time to time, and will post updated versions on the website. Where a change is materially adverse to you, Lucio will use reasonable efforts to give you at least 30 days' advance notice by email or in-product notice before it takes effect, so that you have time to review it. Your continued use of the Products after an update takes effect constitutes your acceptance of the revised Terms and documents.
14. General
(a) Force majeure. Neither party is liable for any delay or failure to perform (other than payment obligations) caused by events beyond its reasonable control.
(b) Assignment. You may not assign these Terms without Lucio's prior written consent. Lucio may assign these Terms to an affiliate or in connection with a merger, acquisition or sale of assets, and your rights under these Terms continue with the assignee.
(c) Notices. Notices to Lucio must be sent to notices@lucioai.com. Lucio may give notice to you by email or through the Products.
(d) Order of precedence. If there is a conflict, a separate signed agreement with a Lucio Group entity prevails, followed by these Terms, and then the incorporated policies.
(e) Severability and waiver. If any provision is held unenforceable, the rest of these Terms continue in effect. A party's failure to enforce a provision is not a waiver of it.
(f) Relationship. The parties are independent contractors. These Terms do not create any partnership, agency, attorney or employment relationship.
(g) Marketing use. We are proud of the firms and practitioners we work with and value each such partnership. Unless you and Lucio agree otherwise in writing, Lucio may use your name and logo to identify you as a user of the Products in its marketing materials, website, sales presentations and customer lists.
