“Indian authorities plan to make a contact-tracing mobile app mandatory for everything from taking public transit to going to work, raising concerns among digital rights experts about privacy and increased surveillance.”

“While authorities have said use of the app is voluntary, it has been made mandatory for food-delivery workers and some other service providers, and all federal government employees.”

“It may also be needed to access public transit and airports when a nationwide lockdown lifts, according to local media reports”
