Smart home app Google Home runs a chromecast legacy package on Android. Private storage holds login session plus home graph cache. The chromecast string dates to the dongle era that grew into the full home platform.
An iOS build exists separately with an unverified ID, so only Android is stated here. Homes, routines and Nest state live server side. Fresh login restores everything after reinstall. Automations re sync with the household. Session stays local while homes stay server side. Graph reloads after login with the same account.
Where Google Home stores this, by platform
/data/data/com.google.android.apps.chromecast.app
Private session and home graph cache for the verified chromecast package. Homes sync from Google servers.
