But does it mean they will take data from everyone nearby? Well, not exactly. They will only record the data of your close contact that stays within 1 meters for 15 minutes or more. For example, if you’re inside the train for just 1 stop and someone shares the radius of 1 meter, it won’t be recorded. But if you’re in the restaurant for more than 15 minutes, anyone that is within 1 meter will be recorded as your close contact. And the best thing about this COCOA app is that your personal details won’t be recorded but instead your phone are given a random code! So you have no worries about your personal details being stored by the app!
