In iPhone → Settings → Stack Exchange → Notices → Quantcast Measurement, it says, near the end:
If you would like to learn more or opt out of such data collection, please use the Disable Analytics setting.
Where's the "Disable Analytics" setting? I can't find it.
I tried the "Disable Metrics" setting, but it only disabled calls to Google Analytics and
/1/track/ios of mobile.stackexchange.com. The calls to m.quantcount.com are still there, even after I restarted the app.
