Care19 Alert respects your privacy and does not ask you to provide personal details, such as name, email, phone number, or address. The Care19 Alert application does not collect location data.
Exposure Notification Operation
Care19 Alert uses the Google\Apple Exposure Notification System (ENS) to help reduce the spread of the coronavirus.
The ENS system maintains your privacy by exchanging random tokens with nearby devices that are also using Care19 Alert or another ENS enabled app. The random tokens, which change every 15 minutes, are kept on your device hidden from the Care19 Alert application in a cryptographically protected data store.
If you are contacted by the Department of Health after testing positive for COVID-19 you may be asked if you are using an ENS enabled application or device. You may then decide to share your ENS tokens by pushing the “Notify Others” button. When you decide to "Notify Others” your tokens and date of creation are securely transmitted to the Association of Public Health Laboratories (APHL).
Periodically, the Care19 Alert app will request an updated list of tokens from the Association of Public Health Laboratories that have a positive COVID-19 diagnosis associated with them. The ENS on your device will then compare positive tokens with the tokens stored on your device and will notify Care19 Alert of the time when you were near someone with a positive diagnosis.
