Castlight Health, Inc. has been awarded TRUSTe’s Privacy Seal, signifying that this privacy policy and practices have been reviewed by TRUSTe for compliance with TRUSTe’s program requirements, including transparency, accountability, and choice regarding the collection and use of your personal information. TRUSTe’s mission, as an independent third party, is to accelerate online trust among consumers and organizations globally through its leading privacy trustmark and innovative trust solutions. If you have questions or complaints regarding our privacy policy or practices, please contact us at Castlight Health, Inc., 121 Spear Street, Suite 300, San Francisco, CA 94105 or privacy@castlighthealth.com. If you are not satisfied with our response, you can contact TRUSTe here. The TRUSTe program covers only information that is collected through this web site.

A. Collection of Information
Because Castlight provides a service for evaluating your health care and health care bills, we ask you for the sort of personal and medical information needed in order to make such evaluations. We will not sell, share or rent this information that is collected in the Castlight service to others in ways different than from what is disclosed in this Statement. Castlight collects information about you from both you and others at several points in our service.

B. Information Collected

  • Information Requests. If you wish to request more information about Castlight prior to registering, you are required to provide contact information (for example, name and e-mail address). It is optional for you to provide additional contact information (for example, health plan and physician). This information will be used by Castlight to contact you about our services.
  • Pre-Registration. You may be pre-registered for Castlight by your health plan or its third party administrator (“TPA”). The pre-registration process requires the collection of contact information about you (for example, name and email address). Your health plan may provide (or may have its TPA provide) additional information based on its information which we collect. This information will be used by Castlight to set up your Castlight account. In order to complete registration to use Castlight, you will be asked to agree to Castlight’s Terms of Use. You may request not to receive information from Castlight at any time.
  • Registration. No matter how you arrive at Castlight, we require the collection of certain contact information as part of the registration process (for example, name, e-mail address, home zip code, birth date, some of which may be provided by your health plan or its TPA to Castlight). You may provide additional contact information (for example, health plan, health plan subscriber ID number, physician name and contact information, email address, home phone number, and home address). We encourage you to provide this information in order to enable optimal use of our service. In many cases, you will be asked to enter this contact information directly. In other cases, that information may be pre-filled if we have already received such information from your health plan (either directly or through its TPA). In circumstances where the information has been received from your health plan (either directly or through its TPA), you will be asked to agree to Castlight’s Terms of Use before being able to use Castlight (and, since the Terms of Use incorporates by reference this Privacy Statement, you are also agreeing to this Privacy Statement). If you arrive at Castlight directly, the registration process requires you to choose a unique identifier (for example, sign in name and password) for your account. If you arrive at Castlight through a customer or business partner site, such site may provide a unique identifier that confirms to Castlight that you are an authorized member from such customer or business partner site. You will be asked to agree to Castlight’s Terms of Use before being able to use Castlight.
  • Communications. The purpose of Castlight is to provide you with the ability to understand, analyze and better organize your health care and related financial information. Certain communications (for example, e-mails and other communications with Castlight) are recorded and maintained by Castlight. Castlight considers these communications to be personal and private and will not use or disclose these communications except as provided for in this Privacy Statement, where required by law or unless you agree to additional use and disclosure of such information.
  • Provided Information. From time to time, your health plan (either directly or through its TPA) may provide Castlight with, or Castlight may otherwise access and collect from such parties, health care financial information (which may include medical or other information contained in their medical records, patient files or bills) or other information about you. This may include sharing of information about you via integration between our service and certain systems used by you and by your health plan or its TPA containing information about you. The provision and sharing of this information is optional by your health plan or its TPA and they may require you to provide them with certain consents. In some cases, our ability to access and collect information from such systems may require additional information from you, such as your log-in information (for example, your user ID and password). Upon your provision of such information, you consent to Castlight using such information solely to log in to such systems to access and collect your information for use in accordance with this Privacy Statement.
  • Payor Information. Castlight requests financial information and any relevant health plan or other payor information from you.

Your anonymous data is combined with the anonymous data of other Castlight users and becomes statistics. We might use aggregate information within Castlight to understand the needs of the Castlight community of users and determine what kinds of programs and services we can offer to you.

Aggregate information may be provided or sold to third parties. Absolutely no personal identifying information is included in the aggregate reports; each individual remains anonymous.
