Collection and Management of Personal Information

OEHHA adheres to the following principles in connection with the collection and management of any personal information obtained by OEHHA:

  1. OEHHA collects personal information on individuals only as allowed by law. Personal information, as defined in the Information Practices Act, is information that identifies or describes an individual including, but not limited to, name, Social Security Number, physical description, home address, home telephone number, education, financial matters, and medical or employment history.
  2. OEHHA limits the collection of Personal Information to what is relevant and necessary to accomplish its lawful purpose. OEHHA does not collect home, business or email addresses, or account information from individuals who simply browse our internet website. OEHHA collects personal information about individuals through our website if an individual provides such information to OEHHA voluntarily through our online services. OEHHA will not knowingly collect, use, or distribute personal information from children under the age of 13 without prior verifiable consent from a parent or guardian.
  3. At the time of collection, we tell individuals who provide personal information about the specific uses for which we will use that information. A privacy notice is also provided on or with the form or webpage portal used to collect personal information. For example, OEHHA may need to know an individual’s e-mail address or telephone number to answer the individual’s questions or to provide requested assistance.
  4. No personal information will be disclosed, made available, or otherwise used for purposes other than those specified without consent, unless authorized by law or regulation. OEHHA may share your personal information and other data with contracted service providers and other state and/or local agencies who support or oversee OEHHA programs, or where the transfer is necessary for the transferee-agency to perform its Constitutional or statutory duties and the use is compatible with a purpose for which the information was collected, and the use or transfer is accounted for in accordance with CA Civil Code § 1798.25. OEHHA may also share personal information about individuals with other government agencies for general law enforcement purposes.
  5. OEHHA takes reasonable precautions to protect the personal information collected or maintained by OEHHA against loss, unauthorized access, illegal use, modification, or disclosure. OEHHA provides Secure Socket Layer (SSL) /Transport Layer Security (TSL) encryption to protect the security of individuals’ personal information during transmission of such information through OEHHA’s website. OEHHA’s staff are trained on the procedures for the management of personal information, including the limitations to the release of information.
  6. OEHHA collects personal information about individuals through our website if an individual provides such information to OEHHA voluntarily through our online services, such as sending an email or submitting forms. We may use your personal information to contact you with information that may be of concern to you. You may opt out of receiving any, or all, of the communications from us by following the unsubscribe link or instructions provided in the email we send or by contacting OEHHA’s Privacy Officer at the contact information provided below.
  7. Submission of an email or form to OEHHA or OEHHA personnel, or communication through the website does not create any attorney-client or other privileged or confidential relationship. Accordingly, do not disclose any information to OEHHA that you wish to remain private or confidential.
