Chaldea User

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

It's not a necessary step if you just use it on one device. Everything in app is available regardless of registered or not.


NO security guarantee! DON'T use frequently used passwords!!!

Game Account

  • Switch among multiple game accounts
  • Game Server

App Data

Root folder for app data(root_path): All data saved here, you can manually backup them.


For Android and iOS, uninstall app will fully delete root_path including your user data.

The root path differs from platforms

OSRoot Path
iOS"File" App/On My iPhone/Chaldea/

The true path can be found in User Data-Data Folder.

Directory Structure:

├── assets  // image/voice assets downloaded path
├── backup  // daily backup of userdata.json
├── game    // app dataset
├── downloads
├── ffo_output
├── logs
├── temp
└── user
    ├── settings.json   // main local settings
    └── userdata.json   // ALL user-related data

User Data Management

  • Online backup: the server provides user data backup and restore.
  • Github Backup: sync data with Github repo. It will fail if SHA mismatch, you can clear SHA then force overwrite remote file.
  • Backup history: the app will create a backup everyday(in backup folder), 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

Disabled. 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.

Game Data Management

The dataset has minimal app requirement. If you cannot update to the latest data, please upgrade app first.

Spoiler Settings

There are 2 similar settings:

  1. "Hide Unreleased Cards":
    • Only turn on filter in svt/cc/ce list page. All data are still there, turn off filter or in other pages, you can still find the unreleased cards.
    • The filter is based on current game account's region setting.
  2. "Delete Unreleased Cards":
    • Delete unreleased Servant/CE/CC data when loading, Events, main stories and mystic codes are kept there.
    • You must restart app to make spoiler change to take effect.
