  • the implications of using apps like instagram in separate user profiles?

I am a grapheneos user. I have to use instagram and facebook for work reasons. I activate always-on/ block connections without a proxy. Since they are in separate profiles, they are completely sandboxed from my personal apps. However, my question is when switch users (unlike logging out in dekstop), the apps from my second profile stay active and connected to internet or not. There was even an post saying that cross-profile notifications are possible. So, I am asking to learn if it is possible for those invasive apps to follow me through IP addresses of the two different profiles.

Thanks for your help.

    Note that all apps are sandboxed on stock Android as well as on GrapheneOS, but putting them in separate user profiles does provide additional isolation.

    GrapheneOS improves user profiles over stock Android in number of ways. One of those is the ability to logout of user profiles when you don't need them. That way Instagram will not keep running in the background.

    Notification forwarding for a user profile is an optional feature. If you don't want notifications forwarded from a specific user profile then you can disable forwarding for that profile. If you've logged out of the user profile anyway, there will be nothing to forward, as the user profile is at rest.

    Note that you can isolate apps further by utilizing the Vanadium sandbox when installing them as progressive web apps (PWAs). That's how I use Instagram and Twitter.
