Linux waydroid question

So I am thinking this and want to know if I’m right.

So on Linux mobile you have waydroid or a fork of.

So I am assuming when running any android app in that container those apps can only see data in the shared folders between main os and android correct ?

Also do those apps have access to info beyond the android system (usually lineage), like can they see main os, imei, etc.

If running a VPN on Linux side will that also apply to the android side or do you need to run a android VPN too ?

Thanks no advance.
