The Aarogya Setu app notably, was launched on April 2. It enables people to assess, on their own, their risk of catching the coronavirus. The app makes its calculations on the basis of a person’s interactions with others, using Bluetooth, algorithms and artificial intelligence.

However, some experts have raised privacy concerns over the app, saying that it needs far more data than what is necessary and falls shorts of the standards set by contact-tracing apps of other countries. Use of GPS-based location data, as per the experts, ‘is a major concern.’

It was in this context that the Congress leader sent out the said tweet today.

Prime Minister Narendra Modi, has, however, repeatedly hailed Arogya Setu, urging everyone to download it. Also, according to the NITI Aayog, it is the fastest app in the world to have recorded five crore downloads.
