Last revised: March 13, 2026

This agreement was written in English (US). To the extent any translated version of this agreement conflicts with the English version, the English version controls.

This Statement of Rights and Responsibilities ("Statement," "Terms," or "TOS") derives from the mission of Volterra ("Volterra" or "we"), and is our Terms of Service that governs our relationship with users who interact with Volterra and Volterra Products and Services. By using or accessing Volterra Products and Services, you agree to this Statement, as updated from time to time in accordance with Section 11.

1. Privacy

Your privacy is important to us. We designed our TOS to make sure that you understand how you can use Volterra to obtain information about functional brain health and how we use your content, data and information. We encourage you to read the TOS and use it to help you make informed decisions. You must agree to the TOS in order to use Volterra Products and Services.

2. Description of Volterra Products and Services

The Services include access to Volterra applications. The use of Volterra applications may include the use of our websites and mobile applications.

If you are a patient or a research participant: It may include the collection of your personal health information (such as medical history and current medications) and personally identifiable information (such as video, image, voice, and movement data, for the purpose of accurately characterizing your brain's functional status, and email address, phone number, and mailing address, for the purpose of uniquely identifying you).

If you are a provider or researcher: It may include personally identifiable data (such as your email address, phone number, mailing address, and clinical licensure number) for the purpose of uniquely identifying you.

Each new feature that augments or enhances the current Service shall be subject to the TOS, unless stated otherwise. You acknowledge and agree that the Services are provided AS IS and are based on the current state of the art of neurobehavioral research and technology available through Volterra at the time of your use.

Volterra is continually innovating in order to provide the best possible experience and the most robust information to its users. You acknowledge and agree that the form and nature of the Services which Volterra provides may change from time to time without prior notice to you. As part of this continuing innovation, you acknowledge and agree that Volterra may stop (permanently or temporarily) providing some Services (or any features within the Services) to you or to users generally at Volterra's sole discretion, without prior notice to you.

Volterra assumes no responsibility for the use of Services outside the terms of this TOS or other applicable terms.

3. User Response

If you are a patient or a research participant:

You are aware that viewing assessment results may provoke strong emotions and thoughts. You will not hold Volterra responsible for any negative emotional or concerning thought consequences that you experience from interacting with Volterra products and services or from receiving assessment results, be they medically relevant or not.

4. Usage Considerations

If you are a patient or a provider:

We do our best to provide patients and providers with educational and supportive information about behavioral, cognitive, emotional, social, and motor functions that are derived from interactions with Volterra's applications. Patients and providers may make incorrect brain health assumptions based on the data that Volterra provides. We recommend against making your own health-related conclusions based on these results. Diagnostic, therapeutic and rehabilitative information may only be interpreted and provided through a specialty provider with the appropriate qualifications. Patients and providers who do not have appropriate specialty qualifications must work with specialists to obtain diagnostic, therapeutic or rehabilitative information.

If you are a research participant or researcher:

We do our best to provide research participants with non-diagnostic and non-medically relevant information that protects study integrity while also satisfying participant curiosity. However, we may provide no information or feedback to research participants should the study protocol prohibit sharing participant data. We do our best to provide researchers with reliable information about the brain function of research participants. We do not provide clinical information to researchers unless specifically stated in our research contract.

5. Data Collection

If you are a patient or research participant:

  1. You guarantee that the information and data that you provide is your own; if you agree to the TOS on behalf of a person for whom you have legal authorization, you confirm that the information provided will be the information of that person.
  2. You give Volterra permission to collect and analyze your speech and vocalizations, body movements, facial expressions, and questionnaire responses (provided by you, a caregiver, guardian, teacher, or other relevant person) in order to quantify your brain functions, and you authorize Volterra to share your results with individuals with whom you authorize Volterra to share your results.
  3. We may ask you for demographic information and other information that may personally identify you such as your name and date of birth. Volterra will never provide information that identifies you by name or email to any third party without receiving your consent to do so, unless required by law.
