No I am trying to say with a connected device using online services, the service provider is going to have access to your data that you use to interact with them.
To a first approximation, everyone in 2024 expects their data and settings to be transferred across devices.
People aren’t working as if it is 2010 when you had to backup and restore devices via iTunes. If I’m out of town somewhere and my phone gets lost, damaged or stolen, I can buy another iPhone, log into my account and everything gets restored as it was.
Just as I expect my watch progress to work when I use Netflix between my phone, iPad, Roku devices etc.
