Unless there&#x27;s techniques I&#x27;m unaware of, I assume you&#x27;re talking about MAC address-based tracking? Apple has been working to eliminate that; they&#x27;ve been using randomized addresses during scanning since iOS 8.<p>The other possibility here is tracking via geolocation or iBeacon, which require an app with location services&#x2F;bluetooth enabled. And in those cases the tracking is most likely based on Apple IDFA&#x2F;Google Advertising Id, so you at least have the option to opt out: <a href="https:&#x2F;&#x2F;dev.twitter.com&#x2F;mopub&#x2F;ui&#x2F;opting-out-interest-based-advertising" rel="nofollow">https:&#x2F;&#x2F;dev.twitter.com&#x2F;mopub&#x2F;ui&#x2F;opting-out-interest-based-a...</a> (assuming the app properly respects the setting).
