We may ask for your feedback on the app and we may conduct other surveys (which are of course voluntary). We may also send you information about new versions of the app or similar apps we may have in the future. Every marketing email sent by us will include a link you can click to opt-out from receiving such emails.

You may also submit your COVID-19 test status and details of any treatment, whether you are a healthcare worker and your use of protective equipment, and visits to hospital or clinics. (All of the foregoing, “Health Data and Other Protected Classifications”)

We process Health Data and Other Protected Classifications for the following purposes:

  • To better understand symptoms of COVID-19
  • To track the spread of COVID-19
  • To advance scientific research into the links between patient's health and their response to infection by COVID-19
  • To identify the exposure of healthcare workers to COVID-19
  • To provide you with the Services
  • In the future we may use this data to help healthcare providers such as hospitals support sick individuals

Personal Data of Children

As noted in the Terms of Use, we do not knowingly collect or solicit Personal Data from children under 18; if you are a child under 18, please do not attempt to register for or otherwise use the Services or send us any Personal Data. If we learn we have collected Personal Data from a child under 18, we will delete that information as quickly as possible. If you believe that a child under 18 may have provided us Personal Data, please contact visit

Sharing of Personal Data

Third party processors: We use third parties to process some of your Personal Data on our behalf, for example security and fraud prevention providers, hosting and other technology and communications providers, analytics providers, and staff augmentation and contract personnel. When we allow them access to your data, we do not permit them to use it for their own purposes. We have in place with each processor a contract that requires them only to process the data on our instructions and to take proper care in using it.

These processors include:

  • Google Cloud Platform
  • SurveyMonkey
  • Segment
  • Expo
  • Google Firebase
  • Amplitude
  • Google G Suite
  • MailChimp
  • Mailgun
  • Intercom
  • Sentry
  • Cloudflare
  • Sqreen

Research Partners and Other Third Parties:

Research Partners: The purpose of our Services is to understand and prevent the spread of COVID-19. In order to do this, we share data with people doing health research, for example, people working in:

  • Hospitals
  • Clinics
  • Universities
  • Health charities
  • Other research institutions

For example, doctors and scientists at Massachusetts General Hospital, Harvard School of Public Health, Stanford University, and King's College London will have access to your Personal Data for the foregoing purpose. Below is a list of institutions with whom we share your Personal Data. (Please note that this list is provided as an example only, and we may add institutions to this list.) Data shared with research partners other than hospitals and teaching institutions will be de-identified.

Transfer: We may restructure how we provide the Services, and as part of that, your Personal Data may be transferred to one of our affiliates or to a not-for-profit organization.

Data Security and Retention

We seek to protect your Personal Data from unauthorized access, use and disclosure using appropriate physical, technical, organizational and administrative security measures based on the type of Personal Data and how we are processing that data. Although we work to protect the security of your account and other data that we hold in our records, please be aware that no method of transmitting data over the Internet or storing data is completely secure. We cannot guarantee the complete security of any data you share with us, and except as expressly required by law, we are not responsible for the theft, destruction, loss or inadvertent disclosure of your information or content.

We are unable today to set any particular time limit on the storage of your sensitive personal data, but we will keep it under regular review and ensure that it is not kept longer than is necessary. By way of example, we currently collect your name so that we are able to pass this on to health care professionals if it is necessary to protect your vital interests or the vital interests of another person. Once this is no longer required, we will delete all names from our records. In contrast, data about the spread of the virus is likely to be extremely valuable for researchers studying both this virus and in understanding epidemic spread for the future. We are likely, therefore, to retain this information for much longer.

In some cases we retain Personal Data for longer, if doing so is necessary to comply with our legal obligations, resolve disputes or is otherwise required by applicable law, rule or regulation. We may further retain information in an anonymous or aggregated form where that information would not identify you personally.

Personal Data Use and Processing Grounds

We will only process your Personal Data if we have a lawful basis for doing so. Lawful bases for processing include consent and our “legitimate interests” or the legitimate interest of others, as further described below.

Legitimate Interests: Our legal basis for processing your Personal Identifiers is our legitimate interest in providing you the Services and developing, improving, marketing and running the Services.

Consent: In some cases, we process Personal Data based on the consent you expressly grant to us at the time we collect such data. When we process Personal Data based on your consent, it will be expressly indicated to you at the point and time of collection. Specifically, we process the category of Health Data and Other Protected Classifications based on your consent. Because of the tight regulatory requirements placed on us, we need your consent to process data about your health, which means that if you do not consent (or withdraw your consent), we cannot allow you to use the app. This is not meant unkindly, we are simply not able to provide you with the service without your consent.

If you wish us to stop processing Health Data and Other Protected Classifications, you may withdraw your consent at any time by visiting

When you withdraw your consent, we will delete all Health Data and Other Protected Classifications we hold about you.

Other Processing Grounds: From time to time we may also need to process Personal Data to comply with a legal obligation, if it is necessary to protect the vital interests of you or other data subjects, or if it is necessary for a task carried out in the public interest.

EU Data Subject Rights

Under the GDPR you have a number of important rights with respect to your Personal Data, including those set forth below. For more information about these rights, or to submit a request, please visit Please note that in some circumstances, we may not be able to fully comply with your request, such as if it is frivolous or extremely impractical, if it jeopardizes the rights of others, or if it is not required by law, but in those circumstances, we will still respond to notify you of such a decision. In some cases, we may also need to you to provide us with additional information, which may include Personal Data, if necessary to verify your identity and the nature of your request.

  • Access: You can request more information about the Personal Data we hold about you and request a copy of such Personal Data. You can also access certain of your Personal Data by logging on to your account.
  • Rectification: If you believe that any Personal Data we are holding about you is incorrect or incomplete, you can request that we correct or supplement such data.

  • Portability: You can ask for a copy of your Personal Data in a machine-readable format. You can also request that we transmit the data to another controller where technically feasible.
  • Objection: You can contact us to let us know that you object to the further use or disclosure of your Personal Data for certain purposes, such as for direct marketing purposes.
