Terms of Service — Propound

Last updated: August 11, 2026 Version: 2026-08-11

These Terms of Service ("Terms") are a binding agreement between you and Data Lab Inc. ("we," "us," or "our") governing your access to and use of the Propound application and related services (the "Service"). By creating an account, installing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

The software you install on your device is also subject to the End-User License Agreement (EULA), and our handling of personal information is described in the Privacy Policy. In the event of a conflict regarding the installed software license, the EULA controls; regarding personal information, the Privacy Policy controls.

1. Eligibility and professional use

You must be at least 18 years old and able to form a binding contract to use the Service. The Service is intended for use by legal professionals and others in a professional capacity. By using the Service, you represent that you are using it for lawful professional purposes and that you have the authority to accept these Terms on behalf of yourself or the organization you represent.

No HIPAA business associate relationship. The Service is not designed for use as a "business associate" under the U.S. Health Insurance Portability and Accountability Act ("HIPAA"), and we do not offer or enter into Business Associate Agreements. If you or your client is a HIPAA covered entity or business associate, you must not use the Service to create, receive, maintain, or transmit protected health information in that capacity. This paragraph does not prohibit processing health-related information you hold outside a HIPAA-regulated capacity (for example, medical records obtained in civil discovery or under a patient authorization when you are not acting on behalf of a covered entity or business associate); such information remains subject to Section 4 and your professional obligations.

2. Not legal advice; no attorney-client relationship

The Service, including any AI-generated content, does not constitute legal advice and is not a substitute for the professional judgment of a licensed attorney. We are not a law firm, we do not practice law, and we do not review your matters. Using the Service does not create an attorney-client relationship between you and us. We are not your lawyer. You are solely responsible for the legal sufficiency, accuracy, and appropriateness of any document, objection, or response you create with the Service, and for exercising independent professional judgment before relying on or filing any output. You must review and verify all output before use.

3. AI features; nature of AI output

The Service offers AI-assisted drafting using a cloud model provided by a third party (Anthropic). AI output is generated by statistical models and may be inaccurate, incomplete, outdated, or otherwise unsuitable, and may produce content that appears authoritative but is wrong ("hallucinations"), including incorrect citations or legal propositions. You must independently verify all AI output. We do not warrant that AI output is accurate, reliable, or fit for any particular purpose. Your use of the cloud AI model is additionally subject to the data flows described in the Privacy Policy.

4. Your responsibilities; client confidentiality

You are responsible for:

• complying with all laws and with your professional, ethical, and bar obligations, including duties of competence and confidentiality;
• determining whether transmitting any matter content to the cloud AI model is appropriate for a given client and matter, and obtaining any client consent required by applicable rules;
• using the redaction feature as appropriate for sensitive matters, understanding that redaction is pattern- and value-based, is not guaranteed to identify or mask every identifier or item of sensitive information, and is not a substitute for your own review of what you submit;
• maintaining the confidentiality of your account credentials and all activity under your account; and
• the accuracy and lawfulness of the content you submit.

You acknowledge that the cloud AI feature transmits the substance of your request to a third party as described in the Privacy Policy, and that you are responsible for that disclosure.

5. Accounts

You must provide accurate information when creating an account and keep it current. You are responsible for safeguarding your credentials and for all activities that occur under your account. Notify us promptly at [email protected] of any unauthorized use.

6. Subscriptions, billing, and cancellation

Certain features require a paid subscription. Billing is handled by Stripe.

• Plans and limits. Free and paid plans are subject to usage limits described in the Service. Paid plans provide higher limits as described at the time of purchase.
• Auto-renewal. Paid subscriptions renew automatically at the end of each billing period at the then-current price, unless you cancel before the renewal date. By subscribing, you authorize recurring charges to your payment method.
• Cancellation. You may cancel at any time through the billing portal. Cancellation takes effect at the end of the current billing period; you retain paid access until then.
• Price changes. We may change prices prospectively; we will provide notice before a price change takes effect, and the new price applies on your next renewal.
• Refunds. Except where required by applicable law, all fees are non-refundable and non-creditable, including for partial billing periods, unused cases or AI generations, or downgrades, and no refund is owed if we terminate your account for your breach of these Terms. If, before the end of a prepaid subscription term, we permanently discontinue the Service or terminate your account other than for your breach, we will refund the prorated unused portion of your prepaid fees; that refund is your sole and exclusive remedy for such discontinuation or termination.
• Taxes. Stated prices may exclude applicable taxes, which you are responsible for.

7. License to use the Service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable right to access and use the Service for your internal professional purposes during your subscription term or period of authorized free use. This Section governs the hosted Service; the installed application is licensed under the EULA.

8. Acceptable use

You agree not to:

• use the Service in violation of any law or third-party right;
• attempt to circumvent usage limits, access controls, billing, or security;
• reverse engineer, decompile, or attempt to extract source code or models except to the extent this restriction is prohibited by law;
• resell, sublicense, or provide the Service as a service bureau to third parties without our written consent;
• use the Service to develop a competing product, or to train or improve another machine-learning model using the Service's outputs;
• upload malware or interfere with the integrity or performance of the Service; or
• use the Service to generate unlawful, infringing, or harmful content.

9. Intellectual property

We and our licensors own all right, title, and interest in the Service, including the application software, models we provide, and all related intellectual property. These Terms do not grant you any rights in our trademarks or branding. As between you and us, you retain ownership of the content you input and, to the extent permitted by applicable law and third-party model terms, the output you generate for your own use. You are responsible for your content and for ensuring you have the rights necessary to submit it. If you send us suggestions, ideas, or other feedback about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use that feedback for any purpose without obligation to you.

10. Third-party services

The Service relies on third-party providers, including Anthropic (cloud AI), Supabase (backend), and Stripe (payments). Your use of features that rely on these providers may be subject to their terms, and we are not responsible for the acts or omissions of third-party providers.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement, and any warranties arising from course of dealing or usage of trade. We do not warrant that the Service will be uninterrupted, error-free, or secure, or that AI output will be accurate or reliable. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.

Redaction. The redaction feature is a pattern- and value-based safeguard provided "as is." We do not warrant that redaction will identify, mask, or restore any particular information, and it may fail to recognize identifiers or sensitive information in your content, mask information incompletely, or restore information imperfectly. You must not rely on redaction as your sole means of protecting privileged, confidential, or personal information. You are solely responsible for reviewing what you submit to AI features and what you serve, file, or otherwise use, in each case regardless of whether redaction is enabled or effective. Any transmission of unmasked information to the cloud AI provider that results from a redaction failure, misconfiguration, or your disabling of the feature is part of the disclosure described in Section 4 for which you are responsible, and is subject to the disclaimers and limitations in these Terms.

Local storage; backups. Your matter content — including cases, uploaded documents, drafts, and chat history — is stored solely in a local database on your device. Except for content transiently processed to provide AI features as described in the Privacy Policy, we do not store or retain copies of your matter content, and we have no ability to recover, restore, or return it in any circumstances, including device failure, loss, or theft; data corruption; software error; a failed or interrupted update; or termination of your account or subscription. YOU ARE SOLELY RESPONSIBLE FOR MAINTAINING REGULAR BACKUPS of your device and data (for example, using Time Machine or an equivalent backup system). To the maximum extent permitted by law, we will have no liability for any loss of, corruption of, or inability to access data stored on your device.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS, ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS, even if advised of the possibility of such damages. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD $100. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

You acknowledge that the disclaimers and limitations in these Terms reflect a reasonable allocation of risk and are an essential basis of the bargain between us.

13. Indemnification

You agree to indemnify, defend, and hold harmless Data Lab Inc. and its members, managers, officers, employees, and agents from any claims, damages, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to your content, your use of the Service (including any use of AI output in client matters or court filings), your violation of these Terms, or your violation of any law, professional obligation, or third-party right. This includes claims brought by your clients, opposing parties, or other individuals whose information is contained in content you submit to the Service, including claims arising from the transmission of that content to the cloud AI provider — whether or not the redaction feature was enabled or effective.

14. Termination

You may stop using the Service and cancel your subscription at any time. We may suspend or terminate your access if you breach these Terms, if required by law, or to protect the Service or other users. Upon termination, your right to use the Service ends. Termination or suspension does not delete, and does not require you to delete, the matter content stored locally on your device — that data remains on your device under your control, although features that depend on our servers (including AI generation and sign-in) will stop working. Sections that by their nature should survive termination (including Sections 2, 9, 11, 12, 13, and 16) will survive.

15. Changes to the Service and these Terms

We may modify the Service or these Terms from time to time. We may change, suspend, limit, or discontinue the Service or any feature at any time, in whole or in part, including changing usage limits or discontinuing the Service entirely. If we permanently discontinue the Service, we will provide reasonable advance notice where practicable and, as provided in Section 6, refund the prorated unused portion of any prepaid subscription fees for your then-current term; that refund is your sole and exclusive remedy for discontinuation. Discontinuation does not delete the matter content stored locally on your device, although features that depend on our servers (including AI generation, sign-in, and subscription management) will no longer function.

When we make material changes to these Terms, we will update the "Last updated" date and version, post the revised Terms at https://propoundlegal.com, and, where appropriate, present an updated notice within the app. Your continued use after the effective date constitutes acceptance.

16. Governing law and dispute resolution

Please read this section carefully — it affects your rights, including your right to bring claims in court and to participate in class actions. You may opt out as described below.

16.1 Governing law. These Terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules. The Federal Arbitration Act governs the interpretation and enforcement of this Section 16.

16.2 Informal resolution first. Before filing any claim, the party with the dispute must send the other a written notice describing the dispute and the relief sought (to us: [email protected]). You and we agree to try in good faith to resolve the dispute informally for 60 days from the notice. Most disputes are resolved this way.

16.3 Binding individual arbitration. Except as provided in Section 16.4, any dispute arising out of or relating to these Terms or the Service that is not resolved informally will be resolved by final and binding arbitration on an individual basis, administered by a recognized U.S. arbitration provider (such as JAMS or the AAA) under its rules applicable to the dispute, before a single arbitrator. The arbitration will be seated in the county where you reside or another mutually agreed location, and may be conducted by videoconference or on written submissions where the rules allow. Judgment on the award may be entered in any court of competent jurisdiction. Each party bears its own attorneys' fees except where the applicable rules or law provide otherwise.

16.4 Exceptions. Either party may (a) bring an individual claim in small-claims court, and (b) seek injunctive or other equitable relief in court for infringement or misuse of intellectual property or confidential information. Nothing in this Section waives rights that cannot be waived under applicable law.

16.5 Class-action waiver. You and we each waive the right to a jury trial and the right to litigate or arbitrate any dispute as a class action, collective action, or representative action (except for representative claims that cannot be waived under applicable law, such as claims under California's Private Attorneys General Act, which are carved out to the extent non-waivable). The arbitrator may award relief only to the individual party seeking it. If the class-action waiver in this Section 16.5 is held unenforceable as to a particular dispute, then the entirety of Sections 16.3 and 16.6 is void as to that dispute, which will proceed in court under Section 16.8.

16.6 Mass filings. If 25 or more similar arbitration demands are filed against us by the same or coordinated counsel, the parties agree the provider will resolve them in staged batches, beginning with up to 10 bellwether arbitrations selected jointly, with the remaining demands held (and applicable statutes of limitation tolled) pending their outcome and a mediated attempt at global resolution.

16.7 Opt-out. You may opt out of Sections 16.3, 16.5, and 16.6 by emailing [email protected] within 30 days of first accepting these Terms, stating your name, account email, and intent to opt out of arbitration. Opting out does not affect any other provision of these Terms.

16.8 If arbitration does not apply. For disputes not subject to arbitration, you and we agree to the exclusive jurisdiction of the state and federal courts located in California, subject to any non-waivable venue rights you have under applicable law.

16.9 Time limit. To the extent permitted by law, any claim arising out of or relating to these Terms or the Service must be filed within one (1) year after the claim accrued, or it is permanently barred.

17. Miscellaneous

These Terms, together with the EULA and Privacy Policy, are the entire agreement between you and us regarding the Service and supersede prior agreements on this subject. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. Nothing in these Terms creates a partnership, agency, or employment relationship. Neither party is liable for delay or failure to perform (other than payment obligations) caused by events beyond its reasonable control, including outages or changes at third-party providers, natural disasters, war, or governmental action.
