The larger the number of infected users who visit any particular location, the larger the hotspot becomes.
The hotspots stay visible for 3 days because the virus has been discovered to have live on a surface for 3 days.
A notification will be sent to uses when they are nearing and when they enter a hotpot so they can use precaution and make sure not to touch any objects that may be infected with COVID-19.
Security is paramount when dealing with users’ location and health data, so we do not ask for any of users’ information, as to not risk any sort of privacy or legal breach.
