5. Your California Privacy Rights


If you are a California resident, you have the following rights under the California Consumer Privacy Act, as amended by the California Privacy Rights Act:

  • The right to know what personal information we have collected about you, including access to personal information collected since January 1, 2022
  • The right to request deletion of personal information, subject to legal exceptions
  • The right to request correction of inaccurate personal information
  • The right to opt out of the sale or sharing of personal information (not applicable, as we do not sell or share personal information for cross-context behavioral advertising)
  • The right to limit the use of Sensitive Personal Information, where applicable
  • The right not to be discriminated against for exercising your privacy rights

Opt-Out Preference Signals: We support the Global Privacy Control (GPC), which is a browser-based signal that allows you to communicate your privacy preferences to websites. When we receive an opt-out request—including a Global Privacy Control signal—we will process it and display confirmation (e.g., 'Opt-out Request Honored') in your privacy settings or on our site. As we do not sell or share personal information for cross-context behavioral advertising, your use of the GPC signal will not change the functionality of our site, but we will honor it as a valid request to opt-out of any future sharing activities.

6. How to Exercise Your Rights


Individuals may submit requests regarding their personal information using one of the methods described below. We will process such requests in accordance with applicable law and our verification requirements.

Where to Submit Requests: To exercise your privacy rights, please contact us at:

  • Telephone: Toll Free: 1-888-336-1987

Verification of Requests: To protect your data, we will verify your identity before fulfilling any request to know, delete, or correct.

  • Verification Process: We will match the identifying information you provide in your request against the information we already maintain in our records. For most requests, this involves confirming two or three data points (such as your email address and a recent interaction date).
  • Sensitive Requests: For requests seeking specific pieces of information or involving sensitive data, we may require a higher degree of verification, which may include a signed declaration under penalty of perjury.
  • Inability to Verify: If we cannot verify your identity to a degree of certainty required by law, we will notify you and explain why we are unable to fulfill the request. We will only use personal information provided in a request for the purpose of verification."

7. Security Measures


We implement administrative, technical, and physical safeguards designed to protect personal information from unauthorized access or disclosure. This includes encrypted storage for sensitive identifiers, restricted access to facility logs, and regular security training for personnel. While we maintain a robust written information security program, no system can be guaranteed 100% secure.
