Sources of, Use of, and Sharing of Personal Information

We describe the sources from which we collect this information and the business and commercial purposes for which we collect this information in the section above entitled Information Collection and Use.

Your Rights and Choices

  • As a California resident, you have rights in relation to your Personal Information; however, your rights are subject to certain exceptions.

  • You may exercise your California privacy rights to know, access and deletion by emailing [email protected]. Please note that we will need to confirm your identity and California residency to process your requests to exercise your rights to know, access or delete your Personal Information. We cannot process your request if you do not provide us with sufficient detail to allow us to understand and respond to it.
    • Right Against Discrimination. You are entitled to exercise the rights described above free from discrimination. This means that we will not penalize you for exercising your rights by taking actions. We will not discriminate against you for exercising your right to know, access, deletion or to opt-out of sales.

EEA Data Transfers.  We rely primarily on Standard Contractual Clauses approved by the European Commission to facilitate the international transfer of Personal Data collected in the EEA and any onward transfer of such information to the extent the business receiving the Personal Data is located in a country that the EU considers to not provide an adequate level of data protection. We may also rely on an adequacy decision of the European Commission confirming an adequate level of data protection in the jurisdiction of the party receiving the information.

Castlight also participate in and have certified our compliance with the EU-U.S. and Swiss-U.S. Privacy Shield Framework as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of personal information transferred from the European Union, the United Kingdom and Switzerland to the United States.

Castlight is responsible for the processing of Personal Data received under the Privacy Shield Framework, and subsequent transfers to a third party acting as an agent on our behalf. We comply with the Privacy Shield Principles for all onward transfers of Personal Data from the European Union and Switzerland, including the onward transfer liability provisions. In the case of onward transfers to these third parties, Castlight may be liable for breaches of Personal Data regarding such transfers; however, all third-party agents and processors used by Castlight will be similarly held to provide at minimum the same level of protection of Personal Data as required by the Privacy Shield Framework.

With respect to Personal Data received or transferred pursuant to the Privacy Shield Framework, Castlight is subject to the regulatory enforcement powers of the U.S. Federal Trade Commission. In certain situations, Castlight may be required to disclose Personal Data in response to lawful requests by public authorities, including to meet national security or law enforcement requirements.
