Effective 2026. Lumen is made by Hadger (IP Shmigirilov).
Lumen has no server, no account, and no analytics. Your check-in (the mood words, an optional line of text, and an optional photo) is processed only on your device to generate today's light, and is never transmitted, stored remotely, or shared. Everything Lumen makes lives in local storage on your iPhone or iPad.
App Store purchases (Apple StoreKit). Everything else, including the check-in, the generated light, the widgets and sharing, works in Airplane Mode. Nothing you feel leaves the device unless you tap Share and hand a card to the system share sheet yourself.
Data Not Collected. There is no account, no identifier, and no tracking of any kind.
Any saved Lumen can be removed in the app at any time; deleting the app deletes everything it stored.
