How does this work:
You just need to register and ON your bluetooth. When you came across another TraceTogether User, it will save the data in both phone and encrypted.
When the TraceTogether user is detected as COVID-19, government will only retrieve the data from the patient and call the list of user contacted. This could help government faster in touch with close contact person without further spread. Data will not be use for other purpose.
TraceTogether helps suppose work fo contact tracers and healthcare workers to combat the spread of COVID-19 and to protect our loved ones and families.
The app will be suspended once epidemic subsides.
