Where another Service provides a separate privacy notice, that notice governs that Service. If there is any conflict between this Notice and the privacy notice presented on a specific Service, the privacy notice presented on the specific Service prevails.

Alto is a corporation registered in the United States (“U.S.”) having its principal place of business at 650 Castro Street, Suite 450 Mountain View, CA 94041. As the operator of the Website, Alto identifies as the controller of the personal data that may be collected or otherwise processed by it in relation to its Website. Alto respects your privacy and is committed to protecting your personal data in accordance with all applicable data protection laws, in particular:

  • United States federal and state privacy laws; and
  • The General Data Protection Regulation (Regulation (EU) 2016/679 and its implementing regulations, as amended from time to time) to the extent that it forms part of the law of England and Wales, Scotland and Northern Ireland by virtue of section 3 of the European Union (Withdrawal) Act 2018 and the Data Protection Act 2018, and their implementing regulations, as amended from time to time (“UK GDPR”).

UK GDPR definitions of “personal data” and “processing”:

  • “Personal data” means any information relating to an identified or identifiable natural person (“data subject”); an identifiable natural person is one who can be identified, directly or indirectly, in particularly by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.
  • “Processing” means any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organization, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction.

Clinical trial activities: This Notice does not apply to personal data processed as part of Alto’s clinical trials, including, for example, data stored on our mental health research registry and trial participants’ data collected through informed consent forms, and the term “Services” should not be interpreted to refer to any such clinical trial(s). These clinical trial activities are governed by separate privacy notices.

Potential clinical trial participants: If you are interested in one of our clinical trials, you will be provided with a separate privacy notice as part of the informed consent form, prior to you agreeing to participate in the study. We do not use your personal data to assess your eligibility for, or other purposes related to, a clinical trial unless and until we first obtain your consent through an informed consent form.

Personnel: This Notice does not apply to personal data that we collect from Alto employees, contractors or job candidates. Such information may be subject to separate privacy notices. For example, you may find the privacy notice for Alto job candidates here.
