Covid Watch:

Reduce the spread of COVID-19 without increasing the spread of surveillance.

Covid WatchCovid Watch aims to empower people to protect their communities from COVID-19 without sacrificing their personal privacy.

Our app uses Bluetooth signals to detect when users are in proximity to each other and alerts them anonymously if they were in contact with someone later confirmed to have COVID-19, without anyone (including the government) being able to track who exposed whom.

We were among the first groups to release an open-source protocol for privacy-preserving, decentralized Bluetooth contact tracing, and have been collaborating with MIT’s SafePaths and CoEpi to make this protocol a standard across apps and jurisdictions. We are aiming to release the full app by mid-April.

About Us
Meet our team, read our mission statement, follow our project timeline, and learn where we fit in among the many apps in this space.
Get answers to questions such as: There is already a lockdown, so what’s the point?, Will this app tell me where or when I was exposed? and What data are you collecting?.
White Paper
Read our March 20 white paper, “Slowing the spread of infectious diseases like COVID-19 with crowdsourced data”. Our modelling shows that a system like Covid Watch can significantly impact transmission and detection.
