COVID-19 Contact Confirming Application

COCOA is an app developed by the Ministry of Health, Labour and Welfare, that informs you if you have been in close contact with an individual who has tested positive for COVID-19.

Here is how this app works:

1 Download COCOA

2 COCOA memorizes all others’ smartphone information when you have close contact (individuals whom you are close contact with for more than 15 minutes and contact within approximately 1 meter)

3 Those who have tested “positive” will register on your COCOA that you have been close to people infected with COVID-19.

4 COCOA notifies those who have been in close contact with this COVID-19 carrier in the past 14 days.

5 COCOA will tell you if you should go to a medical institution or not.

*COCOA is via Bluetooth, and it will NOT require people’s name and telephone number. NO GPS. The government will NOT collect data.
