In response to Coronavirus pandemic, Apple and Google partnered to develop contact-tracing technology to help global health authorities to track the COVID-19 spread. Both companies have released the first version of the exposure notification API for Android and iOS devices. Starting with the iOS 13.5 update on iPhone, you can enable the COVID-19 exposure logging on the device. Follow the steps to turn on exposure notifications on the iPhone.
How Does Contact Tracing Using Exposure Notifications Work?
Here is how it works. The exposure notification API will use Bluetooth on iPhones to send anonymous identifiers to nearby devices that are within range. Other devices will also broadcast such identifiers and receive them. All such identifiers will be stored on the device itself. Whenever a user manually reports themselves as COVID-19 positive, the data is then sent to everyone who is using a contact tracing app. Their device will then go through the log of the devices that they had been within their range over the last 14 days and then inform them if they had come in contact with that COVID-19 positive person. Apple has taken a decentralized approach here as the log of devices remains stored on a user’s device.
Apple and Google aim to assist developers working for health authorities in creating apps that can warn the user about possible contact with an infected person. Over a dozen countries have released such solutions to track the COVID-19 pandemic in the region. But so far, the scale of such apps have been limited to the respective country only. And here is where Apple and Google’s solution fill-in the shoes.
Make no mistake, this isn’t an app from Apple and Google. These are API tools built on a privacy-first decentralized tracing system that require multiple layers of consent, uses Bluetooth signals instead of location tracking, and it is more reliable. Apple said over 22 countries and several US states are already planning to build contact tracing apps using its exposure notification API. Not all contact tracing apps use the Exposure Notification system from Apple and Google. Only the ones that do will show up under the Exposure Logging feature in iOS 13.5.
For a contact tracing app to be successful, user adoption is the key to success. Your personal data or location history will not be tracked via any contact tracing app that uses the exposure notification system from Apple. The contact tracing tech from Apple and Google does not rely on location tracking. It only uses Bluetooth which is more relevant here. Google and Apple are hoping that strong privacy protections will drive the growth of apps using their API tools.

Enable and Disable COVID-19 Exposure Notifications on iPhone
The exposure notification option is disabled by default on the iPhone. You first need to download a compatible app from the App Store, which will ask for permission to use data from exposure notification on the iPhone.
Step 1: Open the Settings app on the iPhone.
Step 2: Navigate to General -> Software Update, and update to iOS 13.5.
Step 3: After a successful update, open the Setting app on the iPhone and go to the Privacy section.
Step 4: From the privacy menu, navigate to Health -> COVID-19 Exposure Logging and enable the toggle. From the same menu, you can disable the toggle as well.
