## What is Circadian AI Sleep & Rhythm?

Circadian AI reads your body clock — not your data.

It turns your Apple Health sleep and your local sunrise into a personal circadian phase, then builds one simple daily plan: when to get morning light, cut caffeine, eat, do NSDR, and wind down for sleep.

Everything runs 100% on your iPhone. No account. No logging. Works offline — nothing about your health ever leaves your phone.

WHY CIRCADIAN AI
• On-device engine — private by design, no servers, no sign-up
• Personal circadian phase from real sleep + HRV + sunrise data
• A clear daily protocol instead of another dashboard of numbers
• Built on published circadian-science principles (light, timing, temperature)

YOUR DAILY PLAN
• Morning light window — when to step outside for the biggest shift
• Caffeine cut-off — timed to protect tonight's sleep
• Meal & movement timing aligned to your rhythm
• NSDR / wind-down prompts to help you downshift in the evening
• Chronotype-aware — early bird or night owl, the plan adapts

WORKS WITH APPLE HEALTH
Connect Sleep and Heart Rate data (optional) and Circadian AI does the rest — reading trends on-device to fine-tune your timing every day.

WHO IT'S FOR
• Anyone rebuilding a sleep schedule or fixing a late body clock
• Shift workers, travelers, and students out of sync
• Biohacking, longevity, and morning-routine fans who want signal, not noise

PRIVATE BY DESIGN
No email. No cloud profile. No tracking. You can use the full plan without handing your data to anyone.
