The categories of information that we may collect are: 

  1.  Information by which you may be personally identified, such as your name, postal address, email address, telephone number, medical record identifiers, IP address, or any other identifier by which you may be contacted online or offline. This may also include other information that has been identified as personal information under CCPA, including your signature, health insurance information, financial information for payment purposes, or other medical information.

We collect this information directly from you when you provide it to us and/or automatically as you navigate through our Websites.

We will only use your personal information for the purposes for which it was collected. We will only collect as much personal data as is reasonably necessary in relation to our business purposes. We may use information that we collect about you or that you provide to us, including any personal information, for the following purposes: to provide our Websites and/or Services to you; to provide you with information, products, or services that you request from us or that we believe may be of interest to you; to contact you; for payment purposes; to provide information to your physicians and other healthcare providers; and to fulfill any other purpose for which you provide it. We may also use and process your personal information for marketing purposes (e.g., to offer or furnish additional information to you about Personalis, its products and/or services), to personalize the types of information you receive from Personalis, to store your interests and preferences in order to customize your use of our Websites, to communicate with you, to verify compliance with the terms and conditions of our Websites, to authenticate customers and users, to evaluate how our Websites are being used and the audience the Websites are reaching, to compile, identify, and analyze trends and interests to help us improve our Websites and/or Services, and to develop and improve the content and operation of our Websites or Services to better serve the needs of our customers and users.

We may also use your personal information to provide you with customer support and to maintain and improve our Websites. We may combine your information with other information about you that is available to us, including information from other sources, in order to maintain accurate records of individuals who engage our services and to assist with the marketing of Personalis products and services. Additionally, your personal information may be aggregated with information from other users of our Websites such that the information no longer personally identifies you. We will take reasonable measures to ensure this de-identified data cannot be associated with you. We will not attempt to re-identify individuals from the aggregated information. Any recipient of de-identified data from Personalis is contractually obligated to also refrain from attempting to re-identify individuals from aggregated data as well as to take steps to ensure the aggregated information cannot be associated with any one individual.
We may use and process the aggregated information for the general purpose of evaluating our market and/or business trends, our customer and user demographics, interests and behavior, our past and future product and/or service offerings and/or pricing, or other aspects of our business. We may share such aggregated information with our business partners, vendors, distributors, or other collaborators for these same purposes. We may also sell or license such aggregate information to one or more third parties for use and processing in a similar manner.

While Personalis makes every reasonable effort to protect information collected through our Websites and Services, based on the volume, scope, and nature of the personal data processed, please be aware that there is always some risk involved when submitting data over the Internet. We cannot guarantee that our Websites are 100% safe from illegal tampering or “hacking.” Any data transmitted over the Internet may be at risk; however, once it is received at Personalis and entered into its database, it has the same protection that Personalis extends to its own confidential information. We track the total number of visitors to our Websites, the number of visitors to each page of the Websites, and the domain names of our visitors’ Internet service providers. No personally identifiable information is gathered in this process.

Personalis’s general retention policy is to retain your personal information for only as long as is necessary for the business purposes for which your personal information was collected. The length of time that Personalis retains any personal information including, but not limited to, first-party cookies, and your name, address, email and genetic information varies depending on the legal basis for processing that personal information, applicable regulations, and Personalis’s need to establish, exercise, or defend legal claims.
