 It will, eventually.
 
+### Can the deviceID be used to track me across the internet
+
+No\*. The device is stored in your browsers localStorage - a data store which is sandboxed only to Home Assistant. That means only Home Assistant can access it. Furthermore, different Home Assistant installations cannot acces each others localStorage.
+
+Some of [my lovelace plugins](https://github.com/thomasloven/hass-config/wiki/My-Lovelace-Plugins) use the device to do different things for different *devices*.

+**\*: There is one exception. If you are using [Fully Kiosk Browser](https://www.ozerov.de/fully-kiosk-browser/), the deviceID is taken from the browser instead of being randomly generated. This deviceID will be the same for each website that asks for it.**
