"The App, called 'AarogyaSetu' joins Digital India for the health and well-being of every Indian. It will enable people to assess themselves the risk of catching the coronavirus infection. It will calculate this based on their interaction with others, using cutting edge bluetooth technology, algorithms and artificial intelligence," an official statement said.
If a person is clinically tested positive with coronavirus infection, the mobile number of the infected person is included in the register maintained by the health ministry and will be updated on the app as well, an IT ministry official explained.
"Once installed in a smartphone through an easy and user-friendly process, the app detects other devices with AarogyaSetu installed that come in the proximity of that phone. The app can then calculate the risk of infection based on sophisticated parameters if any of these contacts are tested positive," the statement said.
The government has announced a 21 lockdown starting March 24 and appealed to everyone to maintain social distancing to avoid the risk of getting infected with the deadly virus which has killed over 40,000 people globally and 50 in India.

The government said that privacy is priority for the app users and the personal data collected by the app is encrypted and will stay secure on the phone till it is needed for facilitating medical intervention.
"Available in 11 languages, the App is ready for pan-India use from day-1 and has highly scalable architecture," the statement said.
