Where Does the YouTube App Store Data?
The main YouTube app keeps watch history in private storage. YouTube Music stays a separate app with separate data.

Video portal YouTube runs the classic android.youtube package on Android with a matching ios.youtube twin. Private storage holds login session plus watch cache and offline videos. The platform twin naming is unusually symmetric for Google apps.
History and subscriptions live server side. Downloads need Premium on the new phone too. Fresh login restores everything watchable after reinstall. Watch Later re syncs with the account. Session stays local while history stays server side. Videos reload after login with the same account.
