GraphineOS works much like this.

I think the reason Andoid doesn't implement it is because they want to be able to sell user data as much as anyone else.

For science!

"Actually, in the terms of service you signed with DirecTV, your NFL Sunday Ticket was set to auto renew after the first free year.

Also.

We've billed you for it for two months, and is now past the point where we can remove it. You have 5 additional payments.

This is in fact also not illegal apparently. Since it's in the terms of service.

If you'd like to sue DirecTV please have your lawyer contact our TEAM of lawyers and we'll be happy to address it."

Worked that soul sucking job for five long years while going to college. Sucked.

I trusted them for years. But, imo, if your rooting your device what your looking for is more functionality and not more safety.

This. Plus factorio

Proxmox.

I spin up VM's and pass through my graphics card. If I'm studying I'll but into kbuntu. If I'm playing or streaming video games, windows 10. I also have several VMs for different purposes. A Win10 with quicken for tracking family expenses. A Proxmox backup server to house backup images from my primary Proxmox cluster, using three old PCs. As an example.

Oh for sure.

There's so much potential here. I wish I could code. Instead I just donate.

I see you, friend.

I mean, you can ask. Idk that it'll happen anytime soon tho.

Started with self hosting Vaultwarden

Moved onto an annual family subscription to Bitwarden

Today I learned what a lolicon was, and yikes indeed.

So, like with a lot of things it depends on your risk tolerance. If you have Android and don't take steps to keep Google from your location, the only extra thing your giving Google with Fitbit is your heart rate, activity level, weight, and menstrual cycle (if applicable). They'll (probably) sell this information in bulk to advertisers so they can link your advertisement ID to ads relevant to you, like ads for stationary bikes or whatever.

When faced with this problem what I said to myself was, "I can't selfhost and build a fitness tracker. So some company is going to get my info. I'll break it up as much as I can." I use Garmin.

Garmin watches are a quality product. I'm fond of the ones with eink displays so I don't have to charge the but once a month. Garmin has my health info. Proton has my emails. Google has my calendar events (Google calendar has no reasonable replacement imo.)

I know you didn't ask for other product recommendations. But all of this is a long winded way of saying the danger is letting one company have all your information.

Companies and governments will always know something about you, unless you live on the the moon. The important thing is keeping track of who knows what and if one company begins to know an unreasonable amount (looking at you Google), then start cutting off that company.

Lastly, consider your political climate. If I'm a woman in Texas I'm likely not going to let any company know when my last period was.
