Not necessarily true with smartphones.<p>I just tried it out. The site acknowledges it tested out ~6M devices so far. It&#x27;s not that big of a number actually. My browser turned out to be unique even though I&#x27;m using a pretty common method (basically just run Chrome on an Android).<p>I&#x27;ve sent the version of Android (which was falsely detected because I upgraded to a newer version, but I&#x27;m still sending the info about the older version, so I&#x27;m assuming this is a bug), my Android model (and build) and my timezone. Anyone who bought the same model from my country (and possibly even the surrounding countries) would probably get the same fingerprint (unless he&#x27;s using a different browser).
