Aarogya Setu contact tracing – How does it work? 

The Aarogya Setu app on your phone detects other devices that have the Aarogya Setu app when they come within the Bluetooth proximity of your phone. When this happens, both the phones securely exchange a digital signature of this interaction, including time, proximity, location and duration. This data is stored on the device of all individuals. In the unfortunate event that any of the people that you came in contact with during the last 14 days, tests positive for COVID-19, the App calculates your risk of infection based on the number of your interactions and the proximity of your interaction and recommends suitable action. This action is displayed on your Home screen. Your updated risk of infection is analysed by Government of India, to facilitate suitable medical interventions, as and when required.

Privacy Features built into the Aarogya Setu

Aarogya Setu has been developed with “privacy-first by design” as a key principle. Aarogya Setu has implemented some of the best and widely accepted privacy features and practices, including anonymization, data minimization, purpose and use limitation and data retention principles.

The 4 key ways in which Aarogya Setu protects the privacy of its users are :

  • Personal information you provide at registration is immediately anonymized and all subsequent transaction are related to a specific Device Identification Number (DiD) that is assigned to you by the Aarogya Setu server.
  • By default, all contact tracing and location information that is collected, is stored locally on your mobile device. This information is only uploaded to the Aarogya Setu server if you have tested positive for COVID-19. The location information is also recorded when you take the self-assessment and it is sent to the server along with your response to self-assessment.
  • All contact tracing and location information stored on the mobile device and not uploaded to the Aarogya Setu servers is permanently deleted from the phone on a rolling 30-day cycle. All your contact tracing and location  information that might have been uploaded to the Aarogya Setu server is permanently deleted 45 days from the date of upload, if you have not tested positive for COVID-19 within that period of time. If you are infected, all contact tracing and location information pertaining to you is permanently deleted from the server 60 days after you are  declared cured of COVID-19.
  • Further, the privacy policy explicitly limits the purposes for which this data will be used i.e. only for assisting you and generating insights to help the Government of India in its COVID-19 mitigation efforts.

Will Aarogya Setu inform other users of the App that I have tested positive?

Aarogya Setu does not reveal your personal identity or your medical condition to any other user of the App or to the public at large. The Government of India may, for the purpose of implementing suitable medical and administrative interventions, contact persons you have come in contact with but will not inform them of your identity or your  condition.
