If it can help to decide or modify your setup, you might consider switching some apps to their website counterpart.
While not all apps have a website equivalent to "install", there are some that works as good as having the app installed.
Sometimes you might lose some features, like live notification.
Google maps website can also be used as a webapp, but you might lose navigation, which for some one is a deal breaker.
Personally I use the website if I have to search for something and then I grab the address and I use another app for navigation (like CoMaps), to try to stick as FOSS as much as possible.
For this specific example, Of course if your area is not properly mapped in OpenStreetMaps (OSM) you can't rely on it as main app for navigation.
Also, Private space might have some perks that come in handy (that the owner profile doesn't have), one of them being hiding or stopping the Private Space.
This means you can stop an entire set of apps altogheter.
Personally I prefer to use the Private Space to put GPS (as in Google Play Services) and all GPS dependant apps, so I can just stop them if I feel/need to.
Also, having most of the stuff replaced with FOSS apps in the owner profile, in the Private Space I basically have no data to be taken, if something should go wrong.
Also, when you reboot your phone, Private Space need a manual unlocking before starting, so it is also a way to avoid apps to "autoboot".
There are probably more paranoid setups than mine, but at a certain point you should draw a line between how much privacy you want and how much convenience you are willing to lose.
entropyartstudio What I'm wondering now is, what privacy features and protections from google's overreach am I giving up in this specific situation?
If you set your permissions properly, not as much as you would think.
While some permissions might be the same for everyone (I would say no calculator should need internet), there are some others that need a "personal touch"
While a lot of people in here will tell you to disable location on your camera, I might argue that it is subjective, maybe you want/need location tied to your pictures.
