Terms of Service

These Terms of Service (“Terms”) are a binding agreement between you and [ENTITY NAME] (“Acumen,” “we,” “us,” or “our”) governing your access to and use of the Acumen website, applications, and related services (collectively, the “Service”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. What Acumen Is — and What It Is Not

Acumen is an educational tool that teaches schema-based clinical reasoning to clinicians-in-training using AI-generated synthetic cases. All patient scenarios presented by the Service are fictional. Acumen does not provide medical advice, diagnosis, or treatment recommendations for any real patient.

Output from the Service is not medical advice and must not be used to make clinical decisions for real patients. You are responsible for exercising independent professional judgment and following the policies of your training program, licensing board, and supervising clinicians. Acumen is not a substitute for formal medical education, supervised clinical training, board-certified references, or professional medical advice.

2. Eligibility

You must be at least 18 years old to use the Service. By creating an account you represent that you are 18 or older and that you are a clinician, student, trainee, or other individual with a legitimate educational interest in clinical reasoning. The Service is not directed to children under 18, and we do not knowingly collect personal information from children under 18.

3. Accounts

You must create an account and verify your email to access most features. You agree to provide accurate registration information, keep your password confidential, and promptly notify us at contact@acumen.app of any unauthorized use. You are responsible for all activity under your account. We may refuse registration, suspend, or terminate accounts that we reasonably believe violate these Terms or our Acceptable Use Policy.

4. No Protected Health Information

The Service is designed for synthetic cases only. You must not enter real patient identifiers, protected health information (PHI), or other identifiable individual health data into any field, prompt, or input. Acumen is not a HIPAA-covered-entity service and is not designed or warranted for the storage or processing of PHI. If you submit such information in violation of this section, you are solely responsible for the consequences and you authorize us to delete the content.

5. Acceptable Use

Your use of the Service is governed by our Acceptable Use Policy, which is incorporated into these Terms by reference. You also agree to comply with the Anthropic Usage Policies when interacting with AI features of the Service.

6. Subscriptions, Fees, and Billing

Some features of the Service require a paid subscription. Subscription plans, fees, and usage limits are displayed at the time of purchase. By subscribing, you authorize us and our payment processor (Stripe) to charge your payment method on a recurring basis until you cancel.

Cancellation. You may cancel at any time through your account settings or by contacting contact@acumen.app. Cancellation takes effect at the end of the current billing period; fees already paid are non-refundable except where required by law.

Changes to fees.We may change subscription fees with at least 30 days’ notice. If you do not accept a price change, you may cancel before the change takes effect.

7. Intellectual Property

The Service — including all clinical content, schemas, illness scripts, software, design, text, graphics, and the Acumen name and branding — is owned by [ENTITY NAME] or its licensors and is protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal, educational use, subject to these Terms.

Your content. You retain ownership of content you submit (such as diagnoses, problem representations, and differential entries). You grant us a worldwide, royalty-free license to host, store, process, and use that content as necessary to operate, improve, and secure the Service, and as described in our Privacy Policy.

8. AI-Generated Output

The Service uses third-party large language models to generate tutoring content. AI output may be inaccurate, incomplete, or inconsistent with current evidence. Do not rely on it for clinical decision-making. Acumen and its providers make no warranty as to the accuracy, completeness, or clinical correctness of AI-generated text.

9. Termination

You may stop using the Service and request account deletion at any time by emailing contact@acumen.app. We may suspend or terminate your access for violation of these Terms, non-payment, or conduct that we reasonably believe could harm other users, third parties, or the Service. Sections that by their nature should survive termination (including Sections 4, 7, 10, 11, 12, and 13) will survive.

10. Disclaimers

The Service is provided “as is” and “as available,” without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted operation. We do not warrant that AI output is accurate, current, or suitable for any clinical use. No advice or information obtained from the Service creates any warranty not expressly stated in these Terms.

11. Limitation of Liability

To the maximum extent permitted by law, Acumen, its owners, affiliates, officers, employees, and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, revenue, data, or goodwill, arising out of or in connection with the Service or these Terms, whether based in contract, tort, strict liability, or otherwise, even if advised of the possibility of such damages.

Our aggregate liability for any claim arising out of or relating 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 preceding the event giving rise to the claim, or (b) one hundred U.S. dollars ($100). Some jurisdictions do not allow the exclusion or limitation of certain damages; in those jurisdictions, our liability is limited to the maximum extent permitted by law.

12. Indemnification

You agree to indemnify, defend, and hold harmless [ENTITY NAME] and its officers, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising from (a) your use of the Service, (b) your violation of these Terms or any applicable law, (c) your infringement of any third-party right, or (d) any real patient information you submit in violation of Section 4.

13. Dispute Resolution — Binding Arbitration and Class-Action Waiver

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

Informal resolution. Before filing any formal claim, you agree to contact us at contact@acumen.app and attempt in good faith to resolve the dispute for at least 30 days.

Binding arbitration. Any dispute, claim, or controversy arising out of or relating to these Terms or the Service that is not resolved informally will be resolved by final and binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. The arbitration will be held in Knox County, Tennessee, or by videoconference. Judgment on the award may be entered in any court of competent jurisdiction.

Class-action waiver.You and Acumen each agree that disputes will be brought only in your or our individual capacity, and not as a plaintiff or class member in any purported class, collective, representative, or consolidated action. The arbitrator may not consolidate more than one person’s claims and may not preside over any form of representative or class proceeding.

Exceptions. Either party may bring an individual action in small-claims court for qualifying disputes, and either party may seek injunctive or equitable relief in a court of competent jurisdiction to protect its intellectual-property rights.

14. Governing Law

These Terms are governed by the laws of the State of Tennessee, United States, without regard to its conflict-of-laws rules. Subject to the arbitration clause in Section 13, the exclusive venue for any permitted court action is the state or federal courts located in Knox County, Tennessee, and each party consents to the personal jurisdiction of those courts.

15. Geographic Scope

The Service is operated from the United States and is intended primarily for users located in the United States. If you access the Service from outside the United States, you do so on your own initiative and are responsible for compliance with local laws. Nothing in these Terms grants any rights under non-U.S. law that cannot be waived.

16. Changes to the Service and to These Terms

We may modify the Service or these Terms at any time. Material changes to these Terms will be announced by updating the “Last updated” date and, where appropriate, by emailing registered users. Your continued use of the Service after the effective date of a revision constitutes acceptance of the revised Terms.

17. Miscellaneous

These Terms, together with the Privacy Policy and the Acceptable Use Policy, constitute the entire agreement between you and Acumen regarding the Service. If any provision is held unenforceable, the remaining provisions will remain in full force. Our failure to enforce any provision is not a waiver. You may not assign these Terms without our consent; we may assign them freely.
