Terms of Service

Version 1.2, published August 8, 2026 · Takes effect September 1, 2026
Version 1.1 remains in force until that date. Originally effective April 11, 2026.
What changed in version 1.2. Section 2 now describes EchoProb's regulatory status in the same terms as the regulatory opinion we hold, rather than more strongly than it. Section 16 is new: it says what happens to your subscription if the company is sold, and commits us to telling you before it does. Nothing about pricing, refunds, or how you use the service has changed.

1. Agreement

By creating an account or using EchoProb, you agree to these Terms of Service ("Terms"). If you do not agree, do not use the service. These Terms constitute a binding agreement between you and EchoProb, LLC.

2. Clinical Decision Support Disclaimer

EchoProb is offered as clinical decision support software rather than as a medical device. It has not been submitted to, reviewed by, cleared, or approved by the FDA or any regulatory authority. EchoProb is intended to support, not replace, the professional judgment of qualified clinicians. All clinical decisions remain the sole responsibility of the treating clinician.

Outputs are guideline-anchored estimates. They have not been validated against clinical outcomes or an expert reference standard, and they are not diagnostic.

3. Intended Users and Patients

EchoProb is intended for use by qualified cardiac sonographers, cardiologists, and structural heart specialists. It supports the echocardiographic assessment of adult patients being evaluated for valvular and structural heart disease. It is not intended for pediatric patients, or for any use beyond echocardiographic severity grading and structural heart device screening.

Sonography students and clinical researchers may hold accounts for training, quality improvement review, and research under appropriate institutional oversight. That does not extend the intended clinical use stated above.

You must be at least 18 years old to create an account.

4. Your Account

5. Prohibited Use

6. Subscriptions and Billing

EchoProb offers a 14-day free trial. After the trial period, continued access to all modules requires a paid subscription. The Mitral Regurgitation module remains accessible on expired trials.

7. Refund Policy

EchoProb offers a 14-day free trial so you can evaluate the service before paying. Because of this:

8. Intellectual Property

The EchoProb scoring algorithm, probability kernel, user interface, and all associated documentation are proprietary. Patent pending. All rights reserved.

You may not copy, modify, distribute, or create derivative works based on EchoProb or its outputs without written permission.

9. Guideline Accuracy

EchoProb references published clinical guidelines from the ASE, EACVI, ACC/AHA, ESC, and TVARC, as well as FDA-cleared device IFUs. We make reasonable efforts to keep thresholds current, but guideline interpretation involves clinical judgment. If you identify a discrepancy between EchoProb and a published guideline, please contact us.

10. Limitation of Liability

To the maximum extent permitted by law:

11. Indemnification

You agree to indemnify and hold harmless EchoProb and its creator from any claims, damages, or expenses arising from your use of the service, including any clinical decisions you make using EchoProb outputs.

12. Availability

We aim for high availability but do not guarantee uptime. We may suspend or discontinue the service at any time with reasonable notice. Scheduled maintenance will be communicated when possible.

13. Privacy

Your use of EchoProb is also governed by our Privacy Policy, which describes how we collect, use, and protect your data.

14. Changes to These Terms

We may update these Terms as the service evolves. Material changes will be communicated via email or in-app notice at least 14 days before taking effect. Continued use after the effective date constitutes acceptance.

15. Governing Law

These Terms are governed by the laws of the State of North Carolina (EchoProb, LLC's state of formation), without regard to conflict of law principles. Any disputes shall be resolved in the state or federal courts located in North Carolina.

16. Assignment and Business Transfers

You may not assign or transfer these Terms, or your account, to anyone else without our written consent.

We may assign these Terms, and transfer the subscriptions and accounts they cover, to a successor in connection with a merger, an acquisition, a corporate reorganization, or a sale of all or substantially all of our assets. If that happens we will tell you by email or in-app notice before the transfer takes effect. The successor takes on our obligations under these Terms and under the Privacy Policy as they stand at the time of the transfer, and must give you notice under Section 14 before changing them. You may cancel or delete your account at any point, including after receiving that notice.

These Terms bind and benefit any permitted successor. Nothing in this section allows us to sell your account information on its own, separate from a transfer of the business.
