A cookie is a small file that can be placed on your computer’s hard disk or on a website server. Cookies do not retrieve information stored on your hard drive and do not corrupt or damage your computer or computer files. For those using our Provider Portal, we may link cookie information to your email address to maintain and recall your preferences within the Provider Portal.

Why we use cookies

We may use cookies and similar tracking technologies to improve or administer the Website, analyze trends, track users’ movements around the Provider Portal, support security features on the Provider Portal, and to gather demographic information about our user base.

How to manage cookie preferences

Depending on their purpose, some cookies will only operate for the length of a single browsing session, while others have a longer life span to ensure that they fulfill their longer-term purposes. Your web browser can be set to allow you to control whether you will accept cookies or reject cookies, to notify you each time a cookie is sent to your browser, or to delete cookies that have already been set. If your browser is set to reject cookies, certain aspects of the Website that are cookie-enabled will not recognize you when you return to the Website, and some Website functionality may be lost. The “Help” section of your browser may tell you how to prevent your browser from accepting cookies. To find out more about cookies you may visit


By using the Provider Portal, you expressly allow us to contact you and use your information as set forth in this Privacy Policy. You may opt-out of receiving marketing emails anytime by clicking the “unsubscribe” link in the email that contains the marketing communication.


The Provider Portal may contain links to other third-party websites. Please be aware that we are not responsible for the privacy practices of third parties and their other websites. This Privacy Policy applies only to the information we collect through the Provider Portal. We encourage you to read the privacy policies of other websites you link to or otherwise visit them.


Whenever reasonably possible, we strive to provide you with choices and control regarding your Personal Information. Upon receiving your request, we will make reasonable efforts, subject to applicable laws, to correct, delete, and/or block your Personal Information from further use to the extent it remains in our possession. If you have questions or requests in connection with your Personal Information or this Privacy Policy, please contact us as noted below.


You may have implemented a “do-not-track” signal through your browser. As there currently is no fixed standard for do-not-track signals, we currently do not respond to do-not-track signals from your web browser.


We will retain Personal Information for as long as necessary to accomplish our purposes for such data as set forth in this Privacy Policy. You can request that your information be deleted by contacting us at the address provided at the bottom of this Privacy Policy. At the time your information is deleted, we will destroy your Personal Information using reasonable data destruction practices. We may, however, retain certain information to comply with legal or contract obligations or to facilitate law enforcement requests.


We may revise this Privacy Policy from time to time. If we decide to change our Privacy Policy, we will post the revised policy here. If changes are significant and materially affect your rights under this Privacy Policy, we may provide a more prominent notice on the Website. In certain cases, we may also provide email notification of the revised Privacy Policy and give you the right to opt out from our use of your Personal Information in accordance with the revised Privacy Policy. However, because we may make changes at any time without notifying you, we suggest that you periodically consult this Privacy Policy.


Certain California residents have additional privacy rights under the California Consumer Privacy Act (“CCPA”). When we operate as a “service provider” (as defined under the CCPA) for our customers and they provide us with your personal information for business purposes under a service contract, the CCPA applies primarily to those customers, not to us. In such cases, we will direct any requests you send us to exercise your rights under the CCPA to the applicable customer.

Your Rights Regarding Your Personal Information

The CCPA gives certain rights to California residents regarding their personal information. We summarize below what those rights are and how you may exercise them. You do not need to have an account with us to exercise these rights.

The CCPA also gives California residents the right to opt out of (or for minors under 16, the ability to opt in to) sales of their personal information. However, we do not and will not sell your personal information. If, in the future, we decide to sell personal information, we will provide you with notice and the right to opt-out of (or for minors, opt-in to) such sales.

Right to Know About the Collection, Use, Disclosure and Sale of Personal Information

Upon providing us with a verified consumer request, you may ask us to disclose certain types of your personal information we have collected and used over the 12-month period prior to the date of your request. You may make this request only twice within any 12-month period. You may request:

  • The categories of personal information we collected about you
  • The categories of sources of the personal information we collected about you
  • The business or commercial purpose for collecting that personal information
  • The categories of third parties with whom we shared that information
  • The specific pieces of personal information we collected about you (except to the extent prohibited under CCPA including, for example, disclosure of Social Security numbers or other government, health insurance or medical identification numbers, account passwords)
  • If we disclosed your personal information for a business purpose, a list identifying the personal information we disclosed to each category of recipient.

Generally, within the preceding 12 months, Sema4 has:

  • Collected the categories of personal information described in Section 2 above from the sources described in Section 2.
  • Disclosed the following personal information about you to our service providers for a business purpose as described in Sections 3 and 4 above: account information and other personal information you provide to us.
Right to Request Deletion of Personal Information

You have the right to submit a verified consumer request at any time that we delete any of your personal information collected and retained by us, unless an exception under the CCPA applies.

If no exception applies, and if we have been able to verify your consumer request, we will delete, aggregate or de-identify your personal information from our records in accordance with the CCPA. We will also direct third parties to whom we have disclosed your personal information to delete it, although we cannot guarantee that such third parties will comply with our direction.

Please note that we may deny your deletion request based on certain provisions of the CCPA, including where it is necessary for us or our service providers to carry out certain business functions, comply with laws or to engage in other internal and lawful uses of the information within the context in which you provided it to us.

Making a Verified Consumer Request to Us

To make a request to exercise your rights under CCPA described above, please submit a verifiable request to us by either:

  • Calling 1-844-SEMA4-34, or
  • Completing and submitting the form available on our Websites at A verifiable consumer request must be made by you or a person registered with the California Secretary of State whom you have authorized to make the request on your behalf. (A representative must be authorized by you in writing or have a valid power of attorney under California probate law.) You may also make a verifiable request to us on behalf of your minor child.

To be considered a proper verified request, your request must:

provide us with sufficient information allowing us to reasonably verify that you are the same person about whom we collected the personal information or the authorized representative, and

describe your request in reasonable detail so we can correctly understand, evaluate and respond to the request.

We may ask you for additional information if needed in order to verify your request, but if we do, we will use such additional information only to verify your identity (or the authority of the representative) and for security and fraud-prevention purposes.

We will also ask you to separately confirm any request to delete personal information.

Responding to Your Verifiable Consumer Request

We will use reasonable efforts to respond to your verifiable consumer request within 45 days of receiving it. If some cases, we may require more time (up to 90 days). If that is the case, we will communicate to you in writing (by postal mail or electronically, at your option) the reason and the length of anticipated delay. We will not be able to fulfill your request if we cannot verify your identity (or the authority of your representative) and confirm that the personal information subject to the request relates to you.

Disclosures we provide in response to a verified consumer request will cover only the 12-month period before we received the request. If your request involves the porting of your personal information, we will use a format that is reasonably designed to allow you to transmit the information to another entity. If we deny part or all of a verified consumer request, we will provide a reasonable explanation for the denial.

We do not charge fees for responding to verifiable consumer request unless they are excessive, repetitive or manifestly unfounded. If we determine that a fee is appropriate, we will provide you with an explanation and a cost estimate before we complete your request.

We will keep records of consumer requests and our responses as required under the CCPA.


We will not discriminate against you for exercising any of your rights under the CCPA. This means that, except where permitted under the CCPA, if you make a request for disclosure or to delete your personal information, we will not (i) deny you goods or services, (ii) charge you different prices for goods or services (e.g., through penalties or withholding of otherwise available discounts), (iii) giving you a different level of goods or services, or (iv) suggesting to you that we will take any of the actions in (i) through (iii).
