However, to date, no state or central government has shown any interest in using the API. The Aarogya Setu app by the central government does not rely on the said API, and will continue to function on its own, so will contact tracing apps developed by other state governments. The privacy protocols of the exposure notification technology by Apple and Google are more stringent than most of these apps, and it remains to be seen if authorities are willing to trade the loss of control for a more stable (and privacy-focussed) technology.
But there is a precedent. The United Kingdom this month said it will ditch its contact tracing app developed by the National Health Service in favour of the decentralised technology by Apple and Google. The NHS contact-tracing app was buffeted with technical glitches, including failure to detect Bluetooth signals and thus contacts, and complaints by privacy advocates. Norway, too, is likely to abandon its contact-tracing app after its data protection authority said it represented a disproportionate intrusion into users’ privacy. India, though, has yet to enact a data protection law.
