## What is Lumen?

Lumen is a private, on-device companion for perimenopause. It pairs simple symptom and cycle tracking with a warm, knowledgeable AI coach and a daily insight that reflects on your recent check-ins — and all of it runs entirely on your iPhone.

Because every bit of AI runs locally with Apple Intelligence, your intimate health data never leaves your device. No account. No servers. No analytics. No subscription.

ON-DEVICE AI COACH
Chat with a supportive, knowledgeable coach about what you're going through. Ask questions, talk things through, and get gentle, personalised guidance — privately. Your conversations stay on your phone.

QUICK SYMPTOM & CYCLE TRACKING
Log how you feel in just a few taps — hot flashes, sleep, mood, energy, anxiety, and your cycle. See gentle trends over the past week so you can spot patterns.

A DAILY INSIGHT, JUST FOR YOU
Once a day, Lumen reads your recent logs and shares a short, encouraging insight with one gentle tip. See it on the Today screen or right from your Home Screen widget.

APPLE HEALTH (OPTIONAL)
Sync hot flashes, cycle, mood, and energy to Apple Health, and let Lumen read last night's sleep to personalise your insight. Everything stays on your device.

GENTLE REMINDERS
Opt in to a daily check-in reminder at a time that suits you.

PRIVATE BY DESIGN
• 100% on-device — no network requests of any kind
• No account, no sign-in, no tracking
• "No Data Collected" privacy label

Lumen offers supportive information, not medical advice. It can't diagnose conditions or prescribe treatment. For severe or sudden symptoms, please contact a clinician or emergency services.
