It is completely normal that you only see a list of Unknown or Unsupported Devices. In fact, this means a COVID-19 privacy-preserving contact tracing app is nearby 👍. In contrast, if your list is empty it is likely that there is no device with the app around 😭.
We use the Web Bluetooth API that is available in modern web browsers. The listed devices should only include mobiles that have a Google/Apple privacy-preserving contact tracing app installed.
The Bluetooth Low Energy-based advertising payload of COVID-19 Exposure Notifications include a special Service UUID.
We filter for the Service UUID (0xFD6F
), to only display devices that have a contact tracing app installed.
Nope. All is happening on your device only. The Web Bluetooth API is designed with privacy in mind 🕵. Thus, the website cannot access the list of devices or any Bluetooth packets. Moreover, there are no Ads, trackers, or cookies used on this website.
The COVID-19 Exposure Notification API protects your privacy 💪. Thus, the MAC addresses shown in your list are completely random and will change every 15 minutes. Read more here.
Some platforms do not support the Web Bluetooth API yet.
