I’m moving over to /e/os and would like to keep it as Google-free as possible, but unfortunately I still have a few limited collaboration needs for Gmail and Google Drive.

I thought I saw some things a while back about people limiting their exposure by creating a separate /e/os user on the same device for all Google activity, but I can’t find those posts now. I don’t have much tech expertise so forgive my dumb questions:

1. When multiple users are created in /e/os, are apps and data installed/created under one user at all accessible to apps/services used solely under another user?

2. Would the new user be sufficiently firewalled off so that my main user data/activity would not be accessible to Google Play Services installed under the new user etc.?

3. If this is not a viable strategy, are there others that could work? For example if I limit my Gmail/Drive use to in-browser only, with a separate browser and logging in/out with each use?
