Yep. And being able to set it as the system assistant and open with the keyboard up is great when you don’t have google on your phone

Protoncalendar plus the tasks.org app

Some feature phones do i think but i don’t know enough about them to have a recommendation, sorry

Best options i can thing of, in no particular order, are the pinephone, a pixel with grapheneos, a light phone, or a feature phone

If you’re on android then you might be able to do a lot of what you want with a custom launcher, if you search “launcher” on fdroid you should find a ton of really solid options
