Australia launched a coronavirus contact tracing app on Sunday. covidsafe lets devices conduct a’digital handshake’ when they come within 5 feet of each other.

Australia’s voluntary app is based on Singapore’s tracetogether software. An infected person must consent to having their data shared.

The Australian government says only health authorities would have access to the data stored on its app. It would not be legally possible for other authorities to access the data.

Apple and Google have announced a framework to develop decentralized contact tracing apps. Information would be anonymized and the companies have pledged to disable the service once the outbreak of the virus has been contained.
