Effective date: October 28, 2026. Developer: Kuan-Hao Chao.
Little Light Below, also named 光落深境, is the mobile game previously developed as 100-Floor Descent. The game does not create accounts, operate a game server, collect personal information, track players, or include advertising, analytics, subscriptions, or in-app purchases.
Information stored on your device
The game stores language, control, sound, haptic and appearance preferences; chapter, relic and medal progress; local records; and an interrupted expedition. Story progress includes restored camp features, rescued wayfarers, viewed scenes, finale completion and an optional resting-light checkpoint with pending discoveries and active play time. Landing Coach may save a practice exercise and the original course to return to. Lantern Echo may store a small recording of your traveler’s positions and active gameplay time so you can race your own successful route.
These values stay in the game’s local storage. Echo routes are not uploaded, shared automatically, or linked to a person or device identifier. The game provides no account or cloud synchronization service. Your operating system may include app data in device backups according to your system settings.
Optional sharing
Sharing happens only when you choose the Share action. A challenge contains the game name, result, mode, course seed, traveler and rules version; a Daily challenge also contains its challenge date. The operating system lets you choose a destination. The game does not add your name, account, contact list, location or device identifier.
Network and device capabilities
Gameplay works offline. The game uses local audio and optional haptic feedback. It does not request access to the camera, microphone, location, contacts, or photo library. Opening a Support or Privacy link uses your system browser and a network connection. The website host processes normal web requests when you visit these pages.
Deleting local data
To delete local game data, use Delete App on iOS, or Clear storage / uninstall on Android. iOS Offload App retains its documents and data. These operating-system actions remove local progress and Coach/Echo data; device backups follow your system settings. There is no developer account or server copy from which we can recover a lost expedition.
Children and policy updates
The game does not collect personal information from children or other players. It contains mild fantasy cave hazards and has no chat or user-generated content. If the game’s data practices change, this policy will be updated with a new effective date.
