TRUSTe Privacy Certification

A. Collection of Information

Because Castlight provides a service for evaluating your healthcare and healthcare 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, which may include, administrators for medical, dental, pharmacy, and behavioral health services (“TPAs”). 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 TPAs provide) additional information. 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 TPAs 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 TPAs). In circumstances where the information has been received from your health plan (either directly or through its TPAs), 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 healthcare 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 TPAs) may provide Castlight with, or Castlight may otherwise access and collect from such parties, healthcare 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 TPAs containing information about you. The provision and sharing of this information is optional by your health plan or its TPAs 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.
  • Log Files. As is true of most websites, Castlight automatically collects and stores in log files the Internet Protocol (IP) address of the computer you are using; the name of the domain and host from which you access the Internet; the browser software you use and your operating system; the date and time you access the service; and the Internet address of the Web site from which you directly linked to Castlight. We may combine this automatically collected log information with other information we collect about you. Castlight uses this log file information to analyze trends, administer the service, and monitor service traffic and usage patterns for internal security purposes and to help make the Castlight service more useful.

C. Use And Disclosure of Your Information

In addition to the uses and disclosures of information outlined above, your information may also be used and disclosed as follows:

  • You can always view the account identifying information you entered in Castlight voluntarily by accessing your account.

  • Supply certain claims data in order to facilitate and coordinate your receipt of certain insurance benefits.
  • Survey you to evaluate and improve the Castlight service. If you participate, we will request certain personal information from you. Participation in these surveys is completely voluntary and you therefore have a choice whether or not to disclose this information. The requested information typically includes contact information (such as name and shipping address), and demographic information (such as age). We use this information to improve the service accuracy and develop new products.
  • We may use a third party service provider to conduct these surveys. We will not share the personal information you provide through a contest or survey with other third parties unless we give you prior notice and choice.

Castlight will not disclose personal information (contact, health and/or billing) to third parties other than as provided for in this Privacy Statement, except when required to do so by law such as to comply with a subpoena or similar legal process, or you have otherwise consented to additional use or disclosure of the information. We may also disclose your personal information when we believe in good faith that disclosure is necessary to protect our rights, protect your safety or the safety of others, investigate fraud, or respond to a government request, and if Castlight is involved in a merger, acquisition, or sale of all or a portion of its assets. You will be notified via email and/or a prominent notice on our Web site of any change in ownership or uses of your personal information, as well as any choices you may have regarding your personal information.
  • Business Partners. Castlight may work with business partners in making our services available to consumers. Our policy is to require companies with whom we do business to support the same privacy policies we do. When you sign up for these services, we will share information only as necessary for the third party to provide related services or assist us in providing our services such as offering customer service, and behavioral health related services. These parties are not allowed to use personal information except for the purpose of providing these services. Note that any disclosures to your health plan will be in strict compliance with the limitations imposed on disclosures of PHI to group health plans under the HIPAA Privacy Rule.
  • Third Parties. If you use Castlight to link to another web site, you may decide to disclose personal information at that web site. For example, you might provide your contact information to obtain an information packet from an organization. Please be aware that in contacting that site, or in providing information on that site, that third party may obtain personal information about you. This Privacy Statement does not apply when you leave Castlight and go to a third party web site from Castlight. We structure the Castlight service so that no personal or health information goes in the search string or URL when you move from the Castlight service to a linked web site. We encourage you to be aware when you leave our service and to read the privacy policy of each and every site that collects personal information.

E. De-identified Information

On occasion, Castlight may make arrangements with certain customers or business partners to share certain de-identified aggregate pattern information in order to assist such customers or business partners improve their service (such as evaluating patterns, utilization, usage and trends). Castlight may also share such information with you or other users of our service. This type of information may be based in part on information related to you, but does not allow for the personal identification of any individual (in other words, it is “patient de-identified”). This information will not be used by the customer or business partner for marketing and/or any purpose other than as set forth above.

  • Castlight removes your identity from your personal information (contact, health and/or financial) and may work with it as anonymous (“de-identified”) information.
  • De-identified individual information is information about a user presented in a form where information about one anonymous user would be indistinguishable from information relating to other anonymous users. De-identified individual information is not in a form that allows anyone studying the information to personally identify any user.
  • Aggregate information is information that describes the habits, usage patterns and/or demographics of users as a group but does not reveal the identity of particular users. Your anonymous data is combined with the anonymous data of other Castlight users and becomes statistics. We may use aggregate information within Castlight to understand the needs of the Castlight user community and determine what kinds of programs and services we can offer to you. Castlight could use this anonymous information to give potential users or business partners a picture of the Castlight community and services. 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.
  • Locator information is your name, electronic messaging address, physical address, and/or other data that enables someone to personally identify you. Castlight and your Internet Access Provider may use Locator information as is necessary to enforce any of the terms of the Castlight Terms of Use.
