COCOA - COVID-19 Contact is an app developed by the Government of Japan providing its users with an effective way of tracking new cases of COVID-19 as they emerge in real-time in Japan. As in other Asian territories like Singapore, China and Korea, this tool is definitely of great help to detect infections and outbreaks that occur anywhere in the country.
The way COCOA - COVID-19 Contact works is very similar to other apps like TraceTogether and Immuni. First you have to sign up on the platform and identify whether you're carriers of the virus or not. That allows the app to create a tracking network to alert citizens in case of contact with the virus.
As far as privacy is concerned, it must be taken into account that the data managed within the platform is totally confidential. In this sense, you'll only ever be identified by means of an encrypted code and no one will ever know your real identity. Plus, the stored parameters are automatically deleted after 14 days.
COCOA - COVID-19 Contact is the app for tracking COVID-19 in Japan. As Japanese citizens authorize installing this tracking tool on their mobile devices, it'll gain greater momentum to influence locating possible outbreaks and new infections.
