Hi Ed,
Look at QGuiApplication::applicationStateChanged signal.
When your app transits from
Qt::ApplicationActive to anything else (Qt::ApplicationSuspended or
Qt::ApplicationInactive),
it's worth to save everything; next user can swipe it out.

It looks to be a rather cross-platform way,
and it may work for iOS as well.

Take care!

Robert
