The CCPA provides consumers (California residents) with specific rights regarding their personal information. This section describes your CCPA rights and explains how to exercise those rights.

4.1. Access to Specific Information and Data Portability Rights

You have the right to request that we disclose certain information to you about our collection and use of your personal information over the past 12 months. Once we receive and confirm your verifiable consumer request (see Exercising Access, Data Portability, and Deletion Rights Section), we will disclose to you:


The categories of sources for the personal information we collected about you.


Our business or commercial purpose for collecting and selling that personal information.


The categories of third parties with whom we share that personal information.


The specific pieces of personal information we collected about you (also called a data portability request).


If we disclosed your personal information for a business purpose, a list with disclosures for a business purpose, identifying the personal information categories that each category of recipient obtained.

4.2. Deletion Request Rights

You have the right to request that we delete any of your personal information that we collected from you and retained, subject to certain exceptions. Once we receive and confirm your verifiable consumer request (see Exercising Access, Data Portability, and Deletion Rights Section), we will delete (and direct our service providers to delete) your personal information from our records, unless an exception applies.

We may deny your deletion request if retaining the information is necessary for us or our service provider(s) to:


Complete the transaction for which we collected the personal information, provide a good or service that you requested, take actions reasonably anticipated within the context of our ongoing business relationship with you or otherwise perform our contract with you.


Detect security incidents, protect against malicious, deceptive, fraudulent, or illegal activity, or prosecute those responsible for such activities.


Debug products to identify and repair errors that impair existing intended functionality.


Exercise free speech, ensure the right of another consumer to exercise their free speech rights, or exercise another right provided for by law.


Comply with the California Electronic Communications Privacy Act (Cal. Penal Code § 1546 et. seq.).


Engage in public or peer-reviewed scientific, historical, or statistical research in the public interest that adheres to all other applicable ethics and privacy laws, when the information’s deletion may likely render impossible or seriously impair the research’s achievement, if you previously provided informed consent.


Enable solely internal uses that are reasonably aligned with consumer expectations based on your relationship with us.


Comply with a legal obligation.


Make other internal and lawful uses of that information that are compatible with the context in which you provided it.

4.3. Exercising Access, Data Portability, and Deletion Rights

To exercise the access, data portability and deletion rights described above, please submit a verifiable consumer request to us by emailing us at [email protected].

Only you, or someone legally authorized to act on your behalf, may make a verifiable consumer request related to your personal information. You may also make a verifiable consumer request on behalf of your minor child.

You may only make a verifiable consumer request for access or data portability twice within a 12-month period. The verifiable consumer request must:


Provide sufficient information that allows us to reasonably verify you are the person about whom we collected personal information or an authorized representative; and


Describe your request with sufficient detail that allows us to properly understand, evaluate, and respond to it.

We cannot respond to your request or provide you with personal information if we cannot verify your identity or authority to make the request and confirm the personal information relates to you.

We will only use personal information provided in a verifiable consumer request to verify the requestor’s identity or authority to make the request.

4.3.1. Response Timing and Format

We endeavor to respond to a verifiable consumer request within forty-five (45) days of its receipt. If we require more time (up to 90 days), we will inform you of the reason and extension period in writing.

Any disclosures we provide will only cover the 12-month period preceding the verifiable consumer request’s receipt. The response we provide will also explain the reasons we cannot comply with a request, if applicable. For data portability requests, we will select a format to provide your personal information that is readily useable and should allow you to transmit the information from one entity to another entity without hindrance.

We do not charge a fee to process or respond to your verifiable consumer request unless it is excessive, repetitive, or manifestly unfounded. If we determine that the request warrants a fee, we will tell you why we made that decision and provide you with a cost estimate before completing your request.

4.4. Personal Information Sales Opt-Out and Opt-In Rights

If you are a California resident and 16 years of age or older, you have the right to direct us to not sell your personal information at any time (the “right to opt-out”). We do not sell the personal information of consumers we actually know are less than 16 years of age, unless we receive affirmative authorization (the “right to opt-in”) from either the consumer who is between 13 and 16 years of age, or the parent or guardian of a consumer less than 13 years of age. Consumers who opt-in to personal information sales may opt-out of future sales at any time.

To exercise the right to opt-out, you (or your authorized representative) may submit a variable notice to [email protected].

Once you make an opt-out request, we will wait at least twelve (12) months before asking you to reauthorize personal information sales.


We will not discriminate against you for exercising any of your CCPA rights. Unless permitted by the CCPA, we will not:


Deny you goods or services.


Charge you different prices or rates for goods or services, including through granting discounts or other benefits, or imposing penalties.


Provide you a different level or quality of goods or services.


Suggest that you may receive a different price or rate for goods or services or a different level or quality of goods or services.


We reserve the right to amend this Privacy Notice at our discretion and at any time. When we make changes to this Privacy Notice, we will post the updated Privacy Notice on our Site and update the Privacy Notice’s effective date. Your continued use of our Site following the posting of changes constitutes your acceptance of such changes.


If you have any questions or comments about this Privacy Notice, the ways in which the Company collects and uses your information described here and in our Site Privacy Policy, your choices and rights regarding such use, or wish to exercise your rights under California law, please do not hesitate to contact our representative responsible for personal information as follows: [email protected].
