I've never owned a TV before but recently purchased a Samsung TV. In terms of privacy, is it recommended I use its internal OS to log into things like Netflix or Disney+, or is it better to use a Chromecast for those things? I figured if I use a Chromecast I can simply not connect my TV to the Internet at all. Of course, it does mean I'll be using a Google product. And what privacy related issues am I opening myself up to in the first place? What kinds of things do TVs and Chromecasts track? Anything else I should be considering?

I have an iphone for work that I'm also allowed to use for personal stuff. I don't use it often, but it has a great camera and is a useful backup for 2FA if I would lose my primary (android) phone. It also gives me the option to use Apple Pay. Paying with my android doesn't work, my bank's app is shitty. It would be useful to have an alternative for my bank card, so I was considering setting up Apple Pay. But I wanted to know: what information will apple get if I use Apple Pay? Do they get the payment details of every payment I make? Will they know anything about payments I make with my card?
