Effective Date: January 1, 2020

Gritstone Oncology, Inc. (“Gritstone,” “we,” “us” or “our”) respects the privacy of visitors to our websites and online services and values the confidence of our customers, partners, patients and employees. This Privacy Policy and Notice of Information Practices (“Privacy Notice”) sets forth Gritstone’s practices regarding the collection, use and disclosure of information that you may provide through the website(s) that we operate, their subdomains, and all portals, applications, products, services, events and any interactive features, applications or other services that link to this Privacy Notice (“Website” or “Sites”), as well as Personal Information provided to Gritstone by any means.  Additional privacy disclosures may be made at the time of collection of the information. Please read the entire Privacy Notice before using our Website or our Services. By using the Website, you agree to abide by the terms of this Privacy Notice. This Privacy Notice is also part of our Terms of Use, which govern your use of the Website.

Collection of Information

We may ask you for some or all of the following types of information when you access various content or features of the Website or submit content, or directly contact us:

  • Contact information, such as name, email address, postal address and telephone number;
  • Job applications, including resumes, cover letters and references;
  • Search queries; and
  • Correspondence and other information that you send to us.
At our clinical trial sites, you may also be asked to provide:
  • Your gender, date of birth, country of domicile, and nationality;
  • Information about your racial or national origin;
  • Information about your health and medical conditions;
  • Information regarding your family and/or your family’s health and medical history; and

Please note that any information taken from you in person may be subject to additional disclosures and/or confidentiality requirements set forth in materials given to you at the time of data collection.  In addition, some or all of this information may be deidentified or anonymized. Please note that our clinical trial sites adhere to all applicable human subject data collection regulations and confidentiality requirements.

We also may collect certain information automatically when you visit the Website, including:

  • Your Internet Protocol (IP) address, which is the number automatically assigned to your computer whenever you access the Internet and that can sometimes be used to derive your general geographic area;
  • Other unique identifiers, including mobile device identification numbers (e.g., IDFA, Android/Google Advertising ID, IMEI);
  • Your browser type and operating system;
  • Your device characteristics;
  • Sites you visited before and after visiting the Sites;
  • Pages you view and links you click on within the Sites, including remembering you and your preferences;
  • Your device location and/or other geolocation information, including the zip code, state, or country from which you accessed the Sites;
  • Information collected through cookies, web beacons and other technologies;
  • Information about your interactions with email messages, such as the links clicked on and whether the messages were received, opened or forwarded; and
  • Standard Server Log Information.

We may use cookies, pixel tags and similar technologies to automatically collect this information. Cookies are small bits of information that are stored by your computer’s web browser. Pixel tags are very small images or small pieces of data embedded in images, also known as “web beacons” or “clear GIFs,” that can recognize cookies, the time and date a page is viewed, a description of the page where the pixel tag is placed, and similar information from your computer or device. By using the Website, you consent to our use of cookies and similar technologies. You can decide if and how your computer will accept a cookie by configuring your preferences or options in your browser. However, if you choose to reject cookies, you may not be able to use certain online products, services or features on the Website.  You can get more information about Cookies and Tracking Technologies, and instructions on how to opt out of these items, in our Cookie Policy.

Response to “Do Not Track” Signals

Do Not Track (“DNT”) is a web browser setting that requests that a web application disable its tracking of an individual user. When you choose to turn on the DNT setting in your browser, your browser sends a special signal to websites, analytics companies, ad networks, plug in providers, and other web services you encounter while browsing to stop tracking your activity. However, because there currently is no industry standard concerning what, if anything, websites should do when they receive such signals, we currently do not take action in response to these signals.  You can learn more about Do Not Track here.

We may use information that we collect through the Website or in person for a variety of purposes, including to:

We maintain a variety of security procedures to help protect against loss, misuse, unauthorized access, disclosure, alteration or destruction of the information you provide through the Website. However, no data transmission over the Internet or stored on a server can be guaranteed to be 100% secure. As a result, while we strive to protect your information and privacy, we cannot guarantee or warrant the security of any information you disclose or transmit to us online and cannot be responsible for the theft, destruction or inadvertent disclosure of your information.  Please see our Terms of Use for additional information.

Children’s Privacy

By using the Site or providing us with any information, you consent to the transfer to, and processing, usage, sharing and storage of your information in the United States and in other countries and territories.

Your California Privacy Rights – Notice to California Residents

As described above, Gritstone collects certain types of personal information about you during your relationship with Gritstone. Under California law, if you are a resident of California, you have the right to request certain information that we collect about you, including:

  3. The business purpose we have for collecting or selling that Personal Information;
  4. The categories of third parties with whom we share such Personal Information; and
  5. The specific pieces of Personal Information we have collected about you.

In addition, if we sold or disclosed your personal information for a business purpose, you may request that we provide you with:

  1. The categories of Personal Information that we sold about you, and the categories of third parties to whom the personal information was sold, by category or categories of Personal Information for each category of third parties to whom the information was sold; or if we have not sold consumers’ Personal Information; and

As a California resident, you also have the right, at any time, to tell us not to sell Personal Information – this is called the “right to opt-out” of the sale of Personal Information.  You also 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, 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 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 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 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; or
  • Make other internal and lawful uses of that information that are compatible with the context in which you provided it.

Please note that if we collected information about you for a single one-time transaction and do not keep that information in the ordinary course of business, that information will not be retained for purposes of a request under this section. In addition, if we have de-identified or anonymized data about you, we are not required to re-identify or otherwise link your identity to that data if it is not otherwise maintained that way in our records.

To exercise the access, data portability, Do Not Sell, and deletion rights described in this section, please submit a verifiable consumer request to us by emailing or writing us with your request at the contact information below.  Please include “California Privacy Rights” as the subject line. Only you 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 must include your full name, email address, and attest to the fact that you are a California resident by including a California postal address in your request. We may require you to confirm your identity and/or legal standing for the request as well as your residency in California in order to obtain the information, and you are only entitled to make this request twice a year. We will respond to your request within 45 days or let you know if we need additional time.
