safe-contact/app

Safe Contact is an open-source iOS/Android app built with Ionic/Cordova that uses Bluetooth to detect and notify users if they've been in contact with someone infected with a virus like COVID-19. It generates a random device ID on first launch, exchanges anonymous Bluetooth signals with nearby devices, and sends meeting data to a backend server while maintaining GDPR compliance by not collecting location or identity information. The app serves both individuals who want to monitor potential virus exposure and epidemiologists seeking statistical data on virus transmission patterns.
