How it Works

  • Download the SlowCOVIDNC Exposure Notification app from the Apple App Store or Google Play Store and enable Bluetooth and Exposure Notifications. Bluetooth must be on for the app to work. After opting-in to receive notifications, the app will generate an anonymous token for your device. A token is a string of random letters which changes every 10-20 minutes and is never linked to your identity or location, but is linked to date. This protects your privacy and security.
  • Through Bluetooth, your phone and the phones around you with the SlowCOVIDNC app work in the background (minimizing battery) to exchange these anonymous tokens every few minutes. Phones record how long they are near each other and the Bluetooth signal strength of their exchanges in order to estimate distance.
  • If you test positive for COVID-19, you may obtain a unique PIN to submit in the app. This voluntary and anonymous reporting notifies others who have downloaded the app that they may have been in close contact with someone in the last 14 days who has tested positive.
  • PINs will be provided to app users who receive a positive COVID-19 test result through a web-based PIN Portal, by contacting the Community Care of North Carolina (CCNC) call center, or by contacting their Local Health Department (LHD).
  • SlowCOVIDNC periodically downloads tokens from the server from the devices of users who have anonymously reported a positive test. Your phone then uses its records of the signal strength and duration of exposures with those tokens to calculate risk and determine if you have met a threshold to receive an Exposure Notification.
