“With SlowCOVIDNC App, North Carolinians have another powerful tool to help slow the spread of COVID-19 right in their pockets. Downloading SlowCOVIDNC is a practical step each of us can take to protect ourselves, our loved ones and our state,”
How SlowCOVIDNC Works
- Download the free SlowCOVIDNC Exposure Notification app from the Apple App Store and the 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 the device. A token is a string of random letters that changes every 10-20 minutes and is never linked to identity or location. This protects app user privacy and security.
- Through Bluetooth, phones 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 an app user tests positive for COVID-19, the individual 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 call center, or by contacting their Local Health Department.
- SlowCOVIDNC periodically downloads tokens from the server from the devices of users who have anonymously reported a positive test. Phones then use records of the signal strength and duration of exposures with those tokens to calculate risk and determine if an app user has met a threshold to receive an exposure notification.
Google Cloud, SpringML, and the North Carolina Department of Health and Human Services worked together to build this app in a matter of weeks with amazing traction in the first week.
