Lumen is a personal reflection-and-art utility for iPhone and iPad, provided as-is for your own use.
Lumen turns a daily mood check-in into a generated image ("your light") that lives on your Home and Lock Screen. It is a reflection and art app. It is not a health, therapy, or mood-diagnosis tool and makes no such claims. Do not use it as the basis for any medical or safety-critical decision.
Lumen Premium is offered as an auto-renewing monthly or annual subscription and a one-time Lifetime purchase, billed through your Apple ID. Subscriptions renew unless cancelled at least 24 hours before the period ends; manage them in Settings → Apple ID → Subscriptions. The free tier remains functional regardless of any purchase.
The check-ins and lights you create are yours and stay on your device. Lumen claims no rights over them.
