Wait, we can in Android. In my OnePlus 12 in the app settings under "data usage" there are two toggles for "disable mobile data" / "disable wifi"

Not present with a Pixel with Android 16, my effective choices are:

1. App can't use mobile data in background

2. App can use mobile data in background except in Data Saver mode

3. App can use mobile data in background regardless of Data Saver mode

For anyone doing comparisons, the literal settings appear under "Mobile Data Usage" as:

* [X] Background Data ("Enable usage of mobile data in the background")

* [ ] Unrestricted mobile data usage ("Allow unrestricted mobile data access when Data Saver is on")

You mean Google-Android.

Wow, thought it was GrapheneOS only, but no.

Confirmed these settings on One+15 on OOS16 (based on Android 16).

Is it also the case for other Android brands?

P.S. I did use it before to turn off ads.

Google's Pixel phones (near stock Android) famously do NOT have the option.

I believe this has been part of LineageOS since before it was called LineageOS. Most custom ROMs have some kind of internet filtering capability.

Some Chinese/Taiwanese brands do it too, but most western brands don't seem to include a firewall.

Xiaomi phones also have it but you can block Wi-Fi only for user (non system) apps. However you can block mobile data access to all apps.

None of the Samsungs I have owned so far had this feature and neither did my last Pixel.

I have an S25 Ultra with the latest version of Android, and these options don't seem to be there at all. I don't have a "data usage" under Permissions for any apps. I do have a Mobile Data section under App Info for any given app, but there's no way to toggle the options you mentioned.
