Plaintiff Zero Terms of Use

Last Updated: May 14, 2026

Welcome to Plaintiff Zero. These Terms of Use (“Terms”) govern your access to and use of our website, services, and software platform (collectively, the “Service”). By accessing or using the Service, you agree to be bound by these Terms.

1. The Plaintiff Zero Service: A Tool for Augmentation

Plaintiff Zero is a sophisticated software platform designed to augment the user’s own work. It is a tool for legal research, document drafting, and practice management. It is not a law firm, does not provide legal services, and is not a substitute for a licensed attorney.

2. No Attorney-Client Relationship & Not Legal Advice (Disclaimer)

This is a critical distinction. Your use of the Service does not create an attorney-client relationship between you and Plaintiff Zero. No information provided by the Service should be construed as legal advice. The platform provides legal information and drafting assistance based on user inputs; it does not and cannot provide personalized legal advice, which involves applying the law to a specific person’s factual circumstances to recommend a course of action. The duties of loyalty, confidentiality (beyond our rigorous data security protocols), and zealous representation that define a legal relationship are absent.

Many users of the Service are licensed attorneys acting on behalf of their own clients. Nothing in these Terms or in your use of the Service creates an attorney-client relationship between you and Plaintiff Zero. The architecture of the Service is, however, designed to be compatible with an attorney’s use of a third-party technological agent in furtherance of the representation of that attorney’s client, consistent with the principles articulated in United States v. Kovel, 296 F.2d 918 (2d Cir. 1961), and its progeny. In Private Mode (Sovereign Shield), the Service is engineered so that Plaintiff Zero personnel cannot access the content of your prompts, documents, or AI Output; in BYOS, Plaintiff Zero does not sit in the inference path and does not receive that content at all. Whether the attorney-client privilege or work-product doctrine in fact attaches to any particular communication or work product processed through the Service is a question of substantive law determined on the specific facts of use, the attorney’s direction, and the law of the relevant jurisdiction. We make no representation or warranty that privilege or work-product protection will be preserved in any given matter, and users who are attorneys remain solely responsible for conducting their practice in a manner consistent with their professional and ethical obligations, including any duty to evaluate the technology they employ in the representation of a client.

3. User Responsibility and Final Authority

You, the user, are solely and ultimately responsible for any work product created using the Service. You are the final author and editor of any document, and you are responsible for exercising your own independent professional judgment in reviewing, validating, and finalizing any content. You represent and warrant that you have all necessary rights to the content you provide and that your use of the Service will comply with all applicable laws and professional rules of conduct.

Notwithstanding anything to the contrary in the foregoing, in no circumstances may Plaintiff Zero be considered as a “publisher” of any content created or generated through the Service. We do not endorse any user-generated content, and we assume no liability for any content created, uploaded, or made available by any user on or through the Service, for any use by any party, or for any loss or damage thereto. Furthermore, Plaintiff Zero shall not be liable for any mistakes, defamation, falsehoods, or any other unlawful or infringing content you or any other party may encounter.

4. AI Services: Your Responsibilities

Certain features of the Service utilize generative artificial intelligence (“AI Services”) to produce text and other content (“AI Output”). Your use of these AI Services is subject to the following conditions:

5. Third-Party Services

The Service enables you to engage and connect with certain third-party services, most notably the foundational large language models (LLMs) that power our AI Services (collectively, “Third-Party Services”). The manner in which Third-Party Services process your data depends on the operational mode you select.

In Public Mode, your prompts and materials are transmitted to the foundation-model provider you select for inference, subject to contractual commitments we have negotiated with those providers (including no-training and zero-data-retention terms). In Private Mode (Sovereign Shield), inference executes inside a Trusted Execution Environment, and the foundation model operates on your data only within that boundary; the provider does not receive your prompts or AI Output in a form it can read or retain. In BYOS, you supply your own foundation-model credentials, and your relationship with that provider is governed exclusively by your contract with them; Plaintiff Zero is not a party to that relationship and does not receive the content of your prompts or AI Output.

You acknowledge and agree that, regardless of the manner in which Third-Party Services may be offered to you, Plaintiff Zero does not endorse any such Third-Party Services and shall not be in any way responsible or liable with respect thereto. Plaintiff Zero will not be a party to, or in any way responsible for monitoring, any interaction or transaction between you and any Third-Party Services, except to the extent expressly set forth in a separate written agreement.

Any and all use of Third-Party Services is done at your own risk and responsibility and may be subject to the legal terms which govern such Third-Party Services, which you are encouraged to review before engaging with them. Plaintiff Zero may, at any time and at its sole discretion, suspend, disable access to, or remove from the Service any Third-Party Services without any liability to you.

Subprocessor List. We maintain a current list of our operational subprocessors—the third-party vendors that handle billing, authentication, error telemetry, hosting, and email delivery—at /legal/subprocessors. None of these operational subprocessors have access to the content of your prompts, AI Output, or uploaded documents in Private Mode or BYOS. We will provide at least sixty (60) days’ written notice before adding, replacing, or expanding the role of any subprocessor listed there, during which you may terminate this agreement without penalty.

5.5 Architectural Commitments

Plaintiff Zero maintains the following architectural commitments for Sovereign Shield Private Mode (Enterprise and Professional tiers) and the Bring Your Own Stack (BYOS) tier:

  1. No AI-provider access during inference. The AI provider’s technical capability to access user-submitted prompts, AI Output, or uploaded documents during inference is structurally prevented by hardware-isolation or browser-only execution, not solely by contractual restriction.
  2. Cryptographic attestation. For Enterprise and Professional tiers, isolation is attested by Platform Configuration Register (PCR) hashes available for the customer’s verification at any time, produced via reproducible builds.
  3. BYOS exclusion. For the BYOS tier, inference executes in the customer’s browser using the customer’s own API credentials with the customer’s chosen AI provider. Plaintiff Zero is structurally excluded from the inference path. The customer’s chosen AI provider receives inference content under the customer’s own contract with that provider; that relationship is between the customer and the provider, and Plaintiff Zero is not a party to it.
  4. 30-day notice for material changes. Plaintiff Zero may not modify, weaken, or disclaim these architectural commitments as to communications generated under these tiers without thirty (30) days’ written notice to affected customers, who may terminate the agreement without penalty upon receipt.

This Section 5.5 survives termination of this agreement as to communications generated during the term.

5.6 HIPAA and Business Associate Agreements

For Enterprise tier customers handling protected health information (PHI), Plaintiff Zero offers a Business Associate Agreement (BAA) covering the dedicated Trusted Execution Environment and all related processing. The BAA is executable as part of the Enterprise tier engagement.

For BYOS tier customers, the customer’s existing BAA with their AI provider applies to inference; Plaintiff Zero orchestrates workflow but does not access content and therefore is not in the BAA chain.

For Public Mode and Professional tier customers, BAA terms vary by AI provider and tenancy posture. Contact legal@plaintiffzero.com for specific applicability.

For context, certain leading legal-AI vendors disclaim HIPAA compliance for core features in their published terms; Plaintiff Zero does not require such a disclaimer because our Sovereign Shield architecture does not use third-party subprocessors in the inference path for Private Mode or BYOS.

6. Intellectual Property

Our Intellectual Property. All rights, title, and interest in and to the Service, including any and all copyrightable materials or any other content thereof which is or may be subject to any intellectual property rights under any applicable law (including any artwork, graphics, images, source and object code, computer code, applications, audio, music, video, designs, animations, interfaces, “look and feel,” methods, products, algorithms, data, interactive features, inventions, trade secrets, logos, domains, trademarks, service marks, and other proprietary identifiers), and any derivations thereof, are owned by and/or licensed to Plaintiff Zero (collectively, “Intellectual Property”). Subject to your full compliance with these Terms and timely payment of all applicable fees, we hereby grant you a non-exclusive, non-transferable, non-sublicensable, fully revocable, limited license to use the Service solely as expressly permitted under these Terms. These Terms do not convey any right or interest in or to our Intellectual Property except for the limited license expressly granted above.

Your Content. You retain all intellectual property rights to the factual content, documents, and other materials you create, upload, and store within the Service (“Your Content”). You grant us a limited, non-exclusive, worldwide, royalty-free license to use, store, process, and display Your Content solely for the purpose of providing and improving the Service to you.

AI-Generated Content. As between you and Plaintiff Zero, you are the owner of the AI Output generated from your prompts. However, you acknowledge that your ownership may be subject to the rights of third-party foundational model providers and the non-unique nature of AI-generated content. You are responsible for ensuring that your use of the AI Output complies with all applicable laws and does not infringe on the rights of any third party.

7. User Accounts

The Service is available only to users who are (a) at least eighteen (18) years of age, (b) able to form a legally binding contract, and (c) a licensed attorney, paralegal, law student, or other legal professional authorized to use legal-research tools in the user’s jurisdiction. To access the Service, you must create an account. You agree to provide accurate, complete, and current information during the registration process. You are responsible for safeguarding your password and for all activities that occur under your account.

8. Fees, Subscriptions, and Chargebacks

Fees. Certain features of the Service require payment of fees (“Fees”). By selecting a paid subscription plan, you agree to pay all applicable Fees. All Fees are non-refundable except as required by law.

Subscriptions & Renewals. Subscriptions automatically renew at the end of each billing cycle unless you cancel through your account management page before the renewal date. For subscriptions with a term of one year or longer, we will send a pre-renewal reminder by email at least fifteen (15) days before the renewal date. We will provide at least thirty (30) days’ advance notice by email of any price increase applicable to your subscription, and any such increase will take effect at your next renewal.

Chargebacks. If we record a decline, chargeback, or other rejection of a charge of any payable Fees on your account (“Chargeback”), this will be considered a breach of your payment obligations. Your use of the Service may be automatically disabled or terminated. In the event a Chargeback is performed, your account may be blocked, and any data contained within may be subject to cancellation. Your access will not resume until you re-subscribe and pay any applicable Fees in full, including any expenses incurred by us for each Chargeback. We reserve the right to dispute any Chargeback by providing the relevant financial institution with information proving the transaction was authorized by you.

9. Cancellation and Termination

Cancellation by User. You may cancel your account or any Service at any time through your account management page. Cancellation takes effect at the end of the then-current billing period for which you have already paid, and you will not be charged for the next renewal. No minimum notice period is required, and no telephone call or written request is necessary to cancel.

Termination by Plaintiff Zero. Failure to comply with any of these Terms or to pay any due Fee shall entitle Plaintiff Zero to suspend (until full payment is made) or terminate your account and access to the Service.

10. Acceptable Use Policy

You agree not to misuse the Service or help anyone else to do so. You agree not to:

11. Disclaimer of Warranties

The Service is provided on an “AS IS” and “AS AVAILABLE” basis, without any warranties of any kind, whether express or implied, including but not limited to, implied warranties of merchantability, fitness for a particular purpose, or non-infringement. Plaintiff Zero does not warrant that the Service will be uninterrupted, secure, or free from errors, viruses, or other harmful components. You agree that your use of the Service is at your own risk. We do not warrant, endorse, guarantee, or assume responsibility for any content, including the AI Output, and we will not be a party to or in any way be responsible for monitoring any transaction between you and third-party providers of products or services.

12. Indemnification

You agree to indemnify and hold harmless Plaintiff Zero and its officers, directors, employees, and agents from and against any claims, disputes, demands, liabilities, damages, losses, and costs and expenses, including, without limitation, reasonable legal and accounting fees arising out of or in any way connected with your access to or use of the Service or Your Content, or your violation of these Terms.

13. Limitation of Liability

To the fullest extent permitted by law, in no event shall Plaintiff Zero, its officers, directors, employees, or agents be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses, resulting from your use of the Service.

In no event shall the aggregate liability of Plaintiff Zero for all claims relating to the Service exceed the greater of one hundred U.S. dollars ($100) or the total amount of fees paid by you to Plaintiff Zero in the three (3) months immediately preceding the event giving rise to the claim.

14. Dispute Resolution

In the event of any dispute, claim, or controversy arising out of or relating to these Terms or the Service, Plaintiff Zero reserves the sole and exclusive right to elect the forum for resolution. At our discretion, we may require that the dispute be resolved by either (a) final and binding arbitration administered by the Dubai International Arbitration Centre (DIAC) under its Arbitration Rules, with the seat of arbitration in the Dubai International Financial Centre (DIFC), the language of the proceedings in English, and a single arbitrator, or (b) litigation in the DIFC Courts. You irrevocably submit to the personal jurisdiction of the DIFC Courts for the purpose of litigating all such claims or disputes and waive any objection to venue or inconvenient forum. Notwithstanding the foregoing, you may assert claims in the DIFC Courts Small Claims Tribunal if your claims qualify.

15. Class Action Waiver

Subject to any applicable law, all disputes between you and Plaintiff Zero shall only be resolved on an individual basis and you shall not have the right to bring any claim against Plaintiff Zero as a plaintiff or a member of a class, consolidated or representative actions (or any other legal proceedings conducted by a group or by representatives on behalf of others). If any court or arbitrator determines that this class action waiver is void or unenforceable for any reason, or that a dispute can proceed on a class basis, then the dispute must be brought exclusively in the DIFC Courts and the arbitration provision in Section 14 shall be deemed null and void with respect to such dispute.

16. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Dubai International Financial Centre (DIFC), notwithstanding any conflict of law provisions.

17. Assignment

You may not assign any of your rights or delegate your obligations under these Terms, whether by operation of law or otherwise, without our prior written consent. We may assign these Terms in their entirety, without your consent, in connection with a merger, acquisition, corporate reorganization, or sale of all or substantially all of our assets.

18. Changes to Terms

We reserve the right to modify these Terms at any time. We will provide notice of any material changes by posting the new Terms on our website. Your continued use of the Service after such changes constitutes your acceptance of the new Terms.
