Chaldea User

A very simple user system, only for user data backup and multi-device synchronization.

User Data Management

Provide user data backup and restore(import). The app will create a backup everyday, you can restore it in backup history.

And Chaldea server also provides a simple backup feature, you need to manually upload to or download from server among multiple devices.

Android External Storage

Android users can select whether to use external storage if SD card exists. When toggle the setting, you can choose to auto migrate app data to target directory. Take attention, auto migration will override files if already exist in target directory. Otherwise, you can choose to manually copy your data.

Do manual BACKUP for your data to avoid accident, mainly in userdata, config and backup.

You need to restart app to let it take effect.

App Dataset Management

The dataset version is just the created date. A full version contains the minimal compatible app version. e.g. 20210922-1.6.0 means the 20210922 version dataset requires your app version at least 1.6.0, or may be incompatible.
