If it’s trying to figure out if you’re watching Stranger Things it can look for when your stationary at home and just needs to record a few seconds at a time every few minutes. I don’t know how the fingerprinting works. It might be able to run locally and not use a ton of power. We’re talking Shazam, not full text transcription.

I believe that’s what ostree is for

Sounds like that’s exactly what they’re trying to do.

Other than the necessities, the one app I allow notifications for is the C-SPAN app. They send maybe 1 notification a week for something like a live presidential address on a news event.

Anything that might create excessive notifications (social media/news) I use as a web app on top of not enabling notifications.

Only texts and calls are audible notifications. Everything else is slient.
