Our Process for Responding to Requests for Access or Deletion Under the CCPA

For requests of California residents for access to or deletion of personal information, we will respond in writing or verbally, if requested, as soon as practicable and in any event generally not more than 45 days after receipt and validation of the request. We may extend this period to 90 days, in which case we will explain to you or your authorized agent why we did so.

If you are legally entitled to such rights, you may designate an agent to submit a request on your behalf. The agent can be a natural person or a business entity that is registered with the California Secretary of State. If you would like to designate an agent to act on your behalf, you and the agent will need to comply with our agent verification process. You will be required to verify your identity by providing us with certain personal information, depending on the nature of the information you require, which we will attempt to match with your information that we maintain. Additionally, we will require that you provide us with written confirmation that you have authorized the agent to act on your behalf and the scope of that authorization. The agent will also be required to provide us with proof of the agency relationship, which may be a declaration confirming and attesting to the agent’s identity and authorization by you to act on your behalf, signed under penalty of perjury. If the agent is a business entity, it will also need to submit evidence that it is registered and in good standing with the California Secretary of State. Information to identify and verify your agent can be submitted through the same mechanism and at the same time that you submit information to verify your identity. Please note that this subsection does not apply when an agent is authorized to act on your behalf pursuant to a valid power of attorney. Any such requests will be processed in accordance with the California law pertaining to powers of attorney.

Requests for Categories of Personal Information

To respond to these requests, we will ask you for at least two pieces of personal information and attempt to match those to your information that we maintain.
