MyCloud App 'Third Party Analytics'

I spotted this item in the Settings page of the Android MyCloud App.

Third Party Analytics? What exactly is this, and what does it do?

It is on by default. I have turned it off. I don’t want my data being used by third parties. I’m not especially happy about an app choosing to default to sending app analytics to a third party either, without asking my express permission

Maybe this will answer your question.

Thanks. It’s off, and staying off…
