  1. When two people using MassNotify on their smartphones are near each other, their phones exchange random codes using Bluetooth. The code is completely anonymous, with no location tracking or exchange of personal information.
  2. When someone in Massachusetts tests positive, they will receive a text message from the Mass. Department of Public Health with a verification link.
  3. The person who tests positive can follow the link to anonymously share their positive test result with other MassNotify users. This is voluntary.
  4. Anyone who also has MassNotify and has been near the user who tested positive for a significant length of time in the last 14 days may receive an anonymous alert that they might have been exposed to COVID-19.
  5. Notifications have a link to information about what to do next to protect yourself and others. They do not contain any information about who tested positive or where the exposure may have happened.
