Starting at iOS 11 Apple now has a means of letting us identify devices that have used something up (e.g. a trial period etc.) without identifying any personally identifying information: https://developer.apple.com/documentation/devicecheck
The above link describes these DeviceCheck APIs. How can we do this in an FMX app? Will also need for Android eventually too.
My intent is to let users vote from the app – but only vote once.
