Where Does the Nintendo Switch App Store Data?
The Switch companion app keeps chat and game data in private storage on Android under a znca ID. Session stays local with the cache.
Last updated
Nintendo Switch companion app (voice chat, SplatNet, parental controls) runs an obscure znca package on Android. Private storage holds Nintendo Account session plus game service cache. The codename string gives no hint of Nintendo, so file hunts for switch come up empty.
An iOS build exists separately with an unverified ID, so only Android is stated here. Game saves themselves live on the console, not the phone. The app is a companion, not storage. Losing its data costs login time, never game progress.

Frequently asked questions
Does Switch app data transfer phones?
Log into the same Nintendo Account on the new phone. Game data and SplatNet history sync from servers. Local data holds session and voice chat cache. Fresh login restores chat services.
What is the exact Switch app package name?
The verified ID is com.nintendo.znca, a legacy codename string. Quote the full znca string; switch guesses match nothing on device. An iOS build exists separately.
