  1. Your California Privacy Rights

A. California Right to Opt-Out (“Shine The Light” Rights)

At this time, we do not sell or otherwise transfer our users’ Personal Information to third parties.

Nonetheless, subject to certain limitations under California’s Shine the Light law, California residents may contact us at support@dellavallelab.com, or as described at the end of this Privacy Policy, to request a list of third parties to whom we disclosed certain personal information for those third parties’ direct marketing purposes during the preceding year. The information we will provide will describe our general practices in the prior calendar year and will not be specific to you.

Your request should indicate that you are a California resident, and you must provide your full current California address, to which we will send our response. Your inquiry must specify “Shine the Light Request” in the subject line of the email or the first line of the letter, and include your California address. We are only required to respond to one such request per individual each year.  We may take reasonable steps to verify your identity and the authenticity of the request.

B. California Right to Know

California users have a right to request disclosure of certain Personal Information we have stored about them over the past 12 months. California users may request this disclosure by contacting us via email at support@dellavallelab.com  with the subject line “Request to Know”, or by sending a letter to our postal address below with the same request. Once we receive and confirm your verifiable user request, we will disclose to you:

  • The categories of personal information we collected about you.
  • The categories of sources for the personal information we collected about you.
  • Our business or commercial purpose for collecting or selling that personal information.
  • The categories of third parties with whom we have shared that personal information.
  • Certain allowable specific pieces of personal information we collected about you (also called a data portability request).
  • If we sold or disclosed your personal information for a business purpose, two separate lists disclosing:
  • sales, identifying the personal information categories that each category of recipient purchased; and
  • disclosures for a business purpose, identifying the personal information categories that each category of recipient obtained.

C. California Right to Delete

California users 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 user request, we will delete (and direct our service providers to delete) your personal information from our (their) records, unless an exception applies; provided, however, that in some cases, strictly for regulatory compliance purposes and to better evidence/honor opt-out/unsubscribe requests (and for no other purposes), we may retain certain items of your personal information on a de-identified and aggregated basis in such a manner that the data no longer identifies you.

We may deny your deletion request if retaining the information is necessary for us or our service providers 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 obligations in connection with 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 rights, ensure the right of another user to exercise her/his 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, but only if you previously provided informed consent.
  • Enable solely internal uses that are reasonably aligned with user 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.

D. California Right to Correct

California users have the right to request that we correct inaccurate personal information that we may maintain about you, such as your name, mailing address, email address, phone number, age, and gender.

E. Exercising California Access and Deletion Rights

For California residents to exercise their access, deletion, and/or correction rights described above, please submit a verifiable user request to us by either:

  • Contacting us through our Website at https://dellavallelab.com/contact/;
  • Phone:  (800) 228-9896; or
  • Sending your request in writing via U.S. mail to: Dellavalle Laboratory, Inc., 516 W. Shaw Ave., Ste. 101, Fresno, CA 93704.

Only a California resident or a person registered with the California Secretary of State that is authorized by a California resident to act on their behalf may make a verifiable California user request related to their personal information. An authorized agent may make a request on your behalf by contacting us at support@dellavallelab.com  with the subject “Proxy Request” together with detailed information about you.  Please note that we will take steps to verify any such request with you, and may deny the request if it cannot be verified.

California residents may only make a verifiable user request for access twice within a 12-month period. The verifiable user request must:

  • Provide sufficient information that allows us to reasonably verify that you are: (1) the California resident about whom we collected personal information; or (2) 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 that the personal information relates to you. Making a verifiable user request does not require you to create an account with us. We will only use personal information provided in a verifiable user request to verify the requestor’s identity or authority to make the request.

California users may designate an authorized agent under the California Consumer Privacy Act to act on their behalf by sending a letter to the email or postal addresses above with a signed letter that includes the name, email address, and date of birth of the user for verification, along with either the user’s signed designation of the authorized agent or a court order or similar legal document designating the authorized agent as acting for the user (for example, a power of attorney or letters testamentary).

F. Response Timing and Format

We endeavor to respond to all verifiable user requests within forty-five (45) days of the receipt thereof. If we require more time (up to ninety (90) days), we will inform you of the reason and extension period in writing. We will deliver our written response by mail or electronically, at your option. Any disclosures we provide will only cover the twelve (12) month period preceding the receipt of your verifiable request. 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 user 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.

G. Non-Discrimination

We will not discriminate against California residents for exercising any of their privacy rights set forth above. In particular, 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; and/or
  • Suggest that you may receive a different price or rate for goods or services or a different level or quality of goods or services.

H. Do Not Track (DNT) Signals

Most web browsers and some mobile operating systems and mobile applications include a Do Not Track (“DNT”) feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this Privacy Notice.

California law requires us to let you know how we respond to web browser DNT signals. Because there currently is not an industry or legal standard for recognizing or honoring DNT signals, we do not respond to them at this time.

  1. Site Policy Regarding Children Under the Age of 18 and Non-US Residents

The Site is intended to comply with the Children’s Online Privacy Protection Act (COPPA) and CCPA. COPPA requires that web site operators never knowingly collect PI from anyone under the age of 13 without prior verifiable parental consent. The Site is not intended for minors under the age of 18 and we do not knowingly collect, use, disclose, or sell PI from minors under the age of 18, including children under the age of 13. Only adults age 18 or over are permitted to use the Site.

By using the Site, you agree to provide us with accurate information concerning your age or identity if we request it. You also agree not to assist children under the age of 18 in accessing the Site or to attempt to contact children under 18 through the Site.

This Site is located within the United States, and we currently do not sell products for delivery outside of California.  Nonetheless, users outside of the United States are advised that this Site and the services advertised on this Site are targeted for users in the United States of America.  Please be aware that if you are located in the European Union, the United Kingdom, Canada, or elsewhere outside of the United States, any information you enter on this Site will be transferred outside of the country where you are to the United States of America, which may not offer an equivalent level of protection to that required in the country where you reside.  European Union residents, in particular, are advised that the United States of America uses a sectoral model of privacy protection that relies on a mix of legislation, governmental regulation, and self-regulation.  Article 26 of the European Union’s Data Protection Directive (Directive 95/46/EC, 1995 O.J. (L 281) 31) allows for transfer of personal data from the European Union to a third country if the individual has unambiguously given his consent to the transfer of personal information, regardless of the third country’s level of protection.  By using this Site or by contacting us through a contact form, you consent to the transfer of all such information to the United States of America which may not offer an equivalent level of protection to that required in the European Union and to the processing of that information by us on our servers located in the United States of America in accordance with this Privacy Policy.

  1. Governing Law, Jurisdiction, and Limitation of Actions

This Privacy Policy, and any disputes arising out of it, will be governed by the laws of the State of California, regardless of its conflict of law principles or those of the jurisdiction where you live or in any other jurisdiction.  You and we agree to submit any disputes arising under this Privacy Policy to the exclusive jurisdiction of the Superior Court of Fresno County, California, or, if federal court jurisdiction exists, the United States District Court for the Eastern District of California, Fresno Division.  You and we agree to waive any jurisdictional, venue, or inconvenient forum objections to such courts (without affecting either party’s rights to remove a case to federal court if permissible), as well as (1) waive any right to a jury trial and (2) waive any right to bring a class action or private attorney general claim.  Any law or regulation providing that the language of a contract shall be construed against the drafter shall not apply to this Privacy Policy.  This paragraph will be interpreted as broadly as applicable law permits.

WHEN YOU AGREE TO THE TERMS OF THIS PRIVACY POLICY, YOU ARE AGREEING TO THE DISPUTE RESOLUTION POLICY SET FORTH IN OUR TERMS OF USE.  THAT SECTION INCLUDES, TO THE FULLEST EXTENT PERMITTED BY LAW: (1) THAT CERTAIN LEGAL PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS PRIVACY POLICY MUST BE BROUGHT IN THE FEDERAL AND STATE COURTS OF THE COUNTY OF MERCED, CALIFORNIA; (2) THAT YOUR CLAIM(S) WILL BE FOREVER WAIVED AND BARRED UNLESS FILED WITHIN ONE YEAR OF THE TIME IN WHICH THE EVENT(S) GIVING RISE TO SUCH CLAIM(S) BEGAN; (3) THAT YOU WAIVE YOUR RIGHT TO BRING, JOIN, OR PARTICIPATE AS A PLAINTIFF OR A CLASS MEMBER IN A CLASS ACTION SUIT, PRIVATE ATTORNEY GENERAL ACTION, OR MULTI-PARTY ARBITRATION BROUGHT AGAINST US, ANY PERSON OR ENTITY RELATED TO US, OR A SERVICE PROVIDER USED BY US TO PROVIDE THE SERVICES; AND (4) THAT YOU IRREVOCABLY WAIVE YOUR RIGHT TO HAVE YOUR CLAIMS AGAINST US TRIED TO A JURY.
