How to use ProtonMail in my Android phone without letting Google know about my Proton account?

How to use ProtonMail in my Android phone without letting Google know about my Proton account? - lemm.ee

I have been slowly degoogling my life by reducing my use of Google apps and switching to FOSS alternatives. I recently created a Proton account and tried to keep it completely isolated from my default Google account so as to not let it know what my Proton mail identity is. I have finished my transition in my desktop to the best of my ability and am planning to start the same with my mobile. The only thing I have done in my Android phone related to Proton is having downloaded ProtonVPN and signed into my account within the app. However I fear by downloading ProtonMail and signing into it, my Android phone would identify the email account, which could make this entire transition useless. Is there a way to avoid this situation or has the damage already been done. What does Google know about my Proton account, if at all?

What Android, LineageOS? Where are you logged in, a Browser or Apps?

Apps are shit, Androids sandboxing security model is hillarious as all preinstalled bloat has all permissions.

Even on LineageOS Google knows

your IP from Connectivity check
your IP from captive portal check
your location and device data from SUPL / A-GPS

but if you are logges into any accounts in apps, no chance.

Simply use your google accounts through a seperate browser and never in “Apps”. Best would be to use ‘shelter’ from F-Droid, create a work profile, install a VPN in either the work profile or your regular one, set it to always on -block other connections in your network settings.

You can do something about the first two points.

Your third point is more difficult. Unless things have changed recently, there isn’t really any way to mitigate your third point. This area is not well understood
