DiDi Australia required app users to download the COVIDSafe app, a technology designed to curb COVID-19 infections developed by the Australian Government. COVIDSafe uses Bluetooth® technology to look for other devices with COVIDSafe installed. An individual’s device will take note of contact with other individuals by securely logging their reference code. If an individual tests positive for COVID-19, the close contact information securely stored in phones can be uploaded and used — with the individual’s consent — by state or territory health officials to quickly trace others who have been exposed to the virus. By requiring users of DiDi services to install COVIDSafe, DiDi supports a national effort to curb infection rates.
