When I install and sign in to Google Hangouts (family won't switch to Signal) on my iPhone, Google Maps suddenly knows about it, and either signs me in automatically to the same Google account or keeps telling me I'm missing out by not signing in. So even if I don't sign in on Maps Google knows that my Google account is on the same device as the Maps app. I don't want Google to know this, but the only solution I've come up with is to uninstall all other Google apps from my phone.
Is there a way to sandbox Google apps so I can sign in to one app without the other apps knowing?
