We will process Personal Data only if and to the extent that at least one of the following legal bases of processing applies:

  • Legitimate interest: We process the information that you provide as well as automatically collected information when the processing is necessary for the purposes of the legitimate interests pursued by Big Health and when these interests are not outweighed by your privacy interests;
  • Performance of a contract: We process the information that you provide when the processing is necessary for the performance of a contract, and specifically the Terms, to which you are a party;
  • Consent: We process Health Information when you have given consent to the processing of Health Information about you for the purposes described above. This consent can be withdrawn at any time.

3. When do we Disclose Personal Data?

Big Health is dedicated to maintaining the confidentiality and integrity of Personal Data. As such, we have policies, procedures, and other safeguards to help protect it from improper use and disclosure.

We follow a Minimum Necessary Access Policy so any required disclosure of Personal Data about you is minimized. The following categories describe the ways in which we disclose Personal Data to persons and entities outside of Big Health. All permitted disclosures will fall within one of the following categories. In addition, there are some uses and disclosures that may require your specific authorization.

Big Health does not disclose Personal Data to third parties for any purpose materially different from the purpose(s) for which it was originally collected.

3.1 Disclosure at Your Request

We may disclose Personal Data relating to your use of the System when requested by you. This disclosure at your request may require written authorization by you.

3.2 Payment

Payment information is stored by third-party vendors who help us deliver the services associated with the System and we are committed to ensuring that all such vendors meet our security and data protection standards. As such, we may use and disclose Personal Data about you to obtain payment for services that we provide to you. For example, we may make disclosures to claim and obtain payment from your health insurer, HMO, or other company that arranges or pays the cost of some or all of your use of the System (“Your Payor”) or to verify that Your Payor will pay for health care.

3.3 Services and Operations

We may disclose Personal Data about you in connection with providing services. To the extent you receive access to the System through your employer or your health plan, our services may include supporting, and sharing information with, your employer’s wellness program, your health plan or third-party administrator or other similar programs. Possible information to be shared may include participation data (i.e., the fact that you used Sleepio), milestone data (e.g., number of sessions you complete or how many diaries you fill out) to allow you to earn incentives and rewards (if those are offered as part of your wellness program), as well as data from your initial sleep questionnaire. Information that identifies you as an individual will not be shared with your employer.

3.4 Third-Party Service Providers

In connection with the System, we may use third-party service providers. Examples of third-party services providers include accounting services, server hosting and email delivery providers, business associates, software analytics vendors and other business partners and reputable companies in the industry who subcontract to us or to those of your employer as our corporate customers, where permitted by law. We may disclose Personal Data about you to our third- party services providers so that they can perform the services. To protect Personal Data about you, we require appropriate contracts or written agreements be in place that safeguard Personal Data about you and limit the use of Personal Data for purposes of providing the services and for no other purpose.

3.5 Third-Party Medical Professionals

With your explicit permission, we may share Health Information about you with third-party medical professionals nominated by you, e.g., through Sleepio Clinic. You can revoke your permission at any time via your account page.

3.6 Public Access to Community Posts

Most of the Sleepio Community isn’t shared publicly and is only visible to other logged-in members. However, there is a subset of ‘General chat’ discussions which may appear in public searches. The profile messages appearing on the Community homepage at any one time may also be visible to non-members. Whilst we’ve taken care to anonymize your username in such cases (as “Sleepio member”), we’re not able to change the content of your comment or message. For this reason, we recommend that you exclude identifying information if you would like to remain anonymous while using the Community. You may want to choose a username that is unique to your Sleepio account and which wouldn’t identify you in any context.

3.7 Threat to Health or Safety

We may use and disclose Personal Data about you when necessary to prevent a serious threat to your health and safety or the health and safety of the public or another person. Any disclosure, however, would only be to someone able to help prevent the threat.

3.8 As Required by Law

Certain laws permit or require certain uses and disclosures of Personal Data for example, in connection with a court order or a government investigation, or for purposes of public health activities, health oversight activities and law enforcement. In these instances, Big Health will only use or disclose Personal Data to the extent the law requires.

3.9 Personal Representatives or Persons Involved with Your Care

We must use and disclose Health Information to anyone who has the legal right to act for you (your personal representative) in order to administer your rights. We may also use or disclose Health Information to a person involved in your care or who helps pay for your care, such as a family member, when you are incapacitated or in an emergency, or when you agree or fail to object when given the opportunity. If you are unavailable or unable to object, we will use our best judgment to decide if the disclosure is in your best interests. Special rules apply regarding when we may disclose Health Information to family members and others involved in a deceased individual's care. We may disclose Health Information to any persons involved, prior to the death, in the care or payment for care of a deceased individual, unless we are aware that doing so would be inconsistent with a preference previously expressed by the deceased.

3.10 Transfer of Business Assets

In the event that we sell or buy any business or assets, we may disclose Personal Data to the prospective seller or buyer of such business or assets. If Big Health or substantially all of its assets are acquired by a third party, Personal Data about you may be one of the transferred assets.
