Where Does HarmonyOS Store Data?
HarmonyOS ties devices and data to the Huawei ID, with app storage per package and Super Device transfers over the account.
Last updated
HarmonyOS centers on the Huawei ID like its Android cousins center on Google. Devices, gallery, contacts, and backups attach to the account with per app storage underneath. Super Device features share across signed in hardware.
Confirm the exact app data entries on your build, since HarmonyOS NEXT diverges from AOSP paths. Cloud backup selection decides what survives: check the list before wiping. Local copies help media, while the account carries everything structural.
Where HarmonyOS stores this, by platform
/storage/emulated/0/Android/data/<package>
Per app private data under each package. The exact layout varies by HarmonyOS version, so match entries on your device. Account backup covers what folders cannot.
Frequently asked questions
How do I move HarmonyOS data to a new phone?

Through Phone Clone or cloud backup under the same Huawei ID. App data restores per app where developers allow it. Confirm the backup contents before wiping the old device.
