Privacy Policy

This Privacy Policy explains how Lumen (the “App”), developed by Caulderon Interactive, handles information. The App is an offline-first light puzzle, runner and creative studio. It does not require an account or sign-in, and Caulderon Interactive does not operate an App backend that receives gameplay data.

Campaign progress and arrangements, runner best scores and settings, earned in-game prisms, shop cosmetic unlocks and tool quantities, studio scenes and saved compositions, classic-mode progress, and audio, haptic and motion preferences are stored locally using Android app storage. This information restores your game and preferences and is not sent to a server operated by us.

The App uses Google Play In-App Updates to ask the Play Store whether a newer version is available and, with your approval, download and install it. Google Play may process device metadata, the installed application version and installed module information under Google's policies. Lumen does not receive your payment details, contacts or personal files through this check.

Light Studio can export artwork as a PNG. Android's system document picker lets you choose the destination and grants access only to the location selected for that export. Lumen does not request broad photo or file access, automatically upload artwork, or retain unrelated access.

Lumen does not request location, contacts, camera, microphone, notification, advertising-ID or broad storage permissions. It can use Android's standard haptic feedback, local audio playback and system document picker. The Play Store manages update downloads.

The only third-party runtime service integrated in this version is Google Play In-App Updates. The App contains no advertising, analytics, crash-reporting, social-login, cloud-save or in-app-billing SDK. Prisms are earned in Lumen and cannot be purchased with real money. See Google's Privacy Policy.

Local data remains until you clear Lumen's storage or uninstall it. Android backup is disabled for the App. Exported PNG artwork remains wherever you chose to save it and must be deleted through your file or gallery app. We cannot retrieve or restore local progress because we do not receive it.

Lumen is a general-audience game and is not designed to collect personal information from children. It has no account, chat, advertising or user-generated-content upload. If you believe information has nevertheless been provided to us, contact us so we can review the matter.

You may decline a flexible update and continue with the installed version, although updating is recommended for fixes and content. You control whether to export artwork and where it is saved. You may erase all App-held data through Android Settings or by uninstalling the App.

We may revise this policy when Lumen or applicable requirements change. Updates will be posted on this page with a revised date. Questions may be sent to support@caulderoninteractive.com.
