Danger.  Danger.  Privacy Concern.

Goodwitch steps up on a privacy soapbox to say:

Answering the question on screen reader detection and privacy concerns.  In
the old days, it was impossible to detect if a screen reader was running.
But times they are a changing.  For example, Apple now provides a way for
developers to know if VoiceOver is running.

   - *UIAccessibilityIsVoiceOverRunning()*
   - https://developer.apple.com/documentation/uikit/1615187-uiac

So...it comes down to...is detection of the use of screen reader (or other
assistive technology) a violation of privacy?   The prevailing answer (in
the a11y community is...this is a violation of privacy.

A few articles you might want to read for context:

   - *Detecting screen readers in analytics: Pros and cons *by Heather
   Burns 20160817  https://www.powermapper.com/blog/accessibility-analytics/
   - *On Screen Reader Detection *by Adrian Roselli written in 2014 but
   updated as recently as 20170577
   - http://blog.adrianroselli.com/2014/03/on-screen-reader-detection.html
   - *Detecting Screen Readers: No *by Dennis Lembree 20140314

Last but not least, the W3C is developing a spec called *IndieUI* which
currently has "screen reader settings" as restricted (private) data.  See
W3C Editors Draft of IndieUI: User Context 1.0 at
-ui-context.html#userScreenReaderSettings  This is not a final spec...nor
is it a law...but to be on the safe side, I advise not collecting this type
of data or making decisions with it.

ADA requirements are not based on statistics.  It only takes one user with
a disability to result in an ADA compliant.

Peace out,
