Terms of Use

Last updated: June 12, 2026

1. Acceptance of These Terms

These Terms of Use (“Terms”) are a binding agreement between you and Lynd Clinical, Inc. (“Lynd Clinical,” “Lynd,” “we,” “us,” or “our”) governing your access to and use of our website at lyndclinical.com, the Lynd platform, and related communications, including text (SMS) messages (collectively, the “Services”). By accessing or using the Services, or by opting in to receive text messages from us, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Services.

2. Who May Use the Services

You must be at least 18 years old, or an authorized professional user acting on behalf of a research site or sponsor, to use the Services. If you are using the Services on behalf of an organization, you represent that you are authorized to bind that organization to these Terms. Where a participant is a minor or otherwise lacks capacity, the Services are used through the research site and the participant’s parent or legally authorized representative.

3. The Services

Lynd Clinical provides a clinical-trial participant recruitment, screening, and electronic-signature platform. The Services are made available to research sites, investigators, and sponsors and their authorized users, and to study participants for limited purposes such as electronically signing documents and receiving verification codes. We may modify, suspend, or discontinue any part of the Services at any time.

4. Acceptable Use

You agree not to:

  • use the Services in violation of any law, regulation, or third-party right;

  • access data you are not authorized to access, or attempt to defeat security, authentication, or access controls;

  • interfere with or disrupt the integrity or performance of the Services;

  • reverse engineer, scrape, or copy the Services except as permitted by law; or

  • use the Services to send unlawful, harassing, or deceptive communications.

5. Accounts and Security

Professional users must maintain unique, named accounts, keep credentials confidential, use multi-factor authentication where required, and promptly notify us of any unauthorized use. You are responsible for activity that occurs under your account.

6. Intellectual Property

The Services, including all software, text, and design (excluding your data and content), are owned by Lynd Clinical or its licensors and are protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable right to use the Services as permitted by these Terms and any applicable subscription agreement. All rights not expressly granted are reserved.

7. Text Messaging (SMS) Program Terms

These SMS Program Terms apply when you opt in to receive text messages from Lynd Clinical. By providing your mobile number and opting in, you agree to these SMS Program Terms.

  • Program description. The Lynd Clinical messaging program sends one-time verification and signing codes to confirm your identity when you electronically sign clinical-trial documents. Where you have separately opted in, we may also send service notifications such as appointment or study reminders. We do not send marketing or promotional text messages.

  • Consent. We send messages only after you opt in (for example, by checking a clearly labeled, un-pre-selected box and providing your mobile number, or by texting a keyword to us). Your consent to receive text messages is not a condition of any purchase, treatment, payment, enrollment, or participation in a study.

  • Message frequency. Message frequency varies. Verification codes are sent only when you request to sign a document; any service notifications are sent as needed.

  • Cost. Message and data rates may apply. Message and data rates are set by your mobile carrier and are your responsibility.

  • Opt out. You can cancel at any time by replying STOP to any message. After you send STOP, we will send a single confirmation message and will not send you further messages unless you opt in again. You may also opt back in at any time by replying START.

  • Help. Reply HELP to any message for assistance, or contact us at privacy@lyndclinical.com.

  • No protected health information by SMS. Our text messages contain only the information needed to complete the action (such as a numeric code) and never include your name, date of birth, MRN, diagnosis, or other health details.

  • Supported carriers. Supported carriers include, but are not limited to, AT&T, Verizon Wireless, T-Mobile, U.S. Cellular, and others. Carriers are not liable for delayed or undelivered messages. Carrier support may vary and is subject to change.

  • Delivery “as is.” SMS delivery depends on your carrier and device and is provided on an “as available” basis. We are not responsible for messages that are delayed, not delivered, or misdirected by a carrier or device.

  • Privacy. Your information is handled as described in our Privacy Policy, which includes our commitment that no mobile information will be shared with third parties or affiliates for marketing or promotional purposes, and that text messaging originator opt-in data and consent will not be shared with any third parties.

8. Disclaimers

EXCEPT AS EXPRESSLY STATED IN A SEPARATE WRITTEN AGREEMENT, THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. THE SERVICES DO NOT PROVIDE MEDICAL ADVICE AND ARE NOT A SUBSTITUTE FOR PROFESSIONAL JUDGMENT OR CARE.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LYND CLINICAL AND ITS SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICES, INCLUDING ANY FAILED, DELAYED, OR MISDIRECTED MESSAGE. NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED UNDER APPLICABLE LAW.

10. Indemnification

You agree to indemnify and hold harmless Lynd Clinical from any claims, damages, or expenses (including reasonable attorneys’ fees) arising out of your misuse of the Services or violation of these Terms or applicable law.

11. Governing Law

These Terms are governed by the laws of the State of Delaware, without regard to its conflict-of-laws rules. Subject to any separate written agreement between you and Lynd Clinical, you agree to the exclusive jurisdiction of the state and federal courts located in Delaware for any dispute arising out of or relating to these Terms or the Services.

12. Changes to These Terms

We may update these Terms from time to time. We will post the updated version here and revise the “Last updated” date above. Your continued use of the Services after a change takes effect constitutes acceptance of the updated Terms.
