## What is Lumi?

Meet Lumi, your little cycle companion.

Lumi is a calm, private period and cycle tracker with a friendly character who keeps you company through every phase. Log your period and feelings in a tap, see what's coming, and get gentle ideas for how to care for yourself, all without an account, ads or a cloud.

YOUR DAY WITH LUMI
• Lumi greets you and asks how you're feeling, then reacts with her own expressions
• Log happy, calm, tired, anxious, irritable or sad in one tap
• No time to log? Lumi makes a gentle guess based on your past cycles

A CALENDAR THAT LOOKS AHEAD
• Log or edit any day: period on or off, light, medium or heavy flow, and your mood
• See predicted periods, PMS days and estimated ovulation months ahead
• Plan a trip: pick your dates and see what's likely while you're away
• Predictions learn from your own history and show how sure they are

ASK LUMI
• Ideas for food, drinks, mood, movement and rest that fit your current phase
• Chat with Lumi about your cycle using an AI that runs entirely on your iPhone
• Your questions and answers never leave your device

INSIGHTS
• Your cycle history at a glance: cycle length, period length and logs
• Patterns in your symptoms and how your cycle length changes over time

GENTLE REMINDERS
• Optional heads-ups before your period and PMS days, plus a daily check-in
• Pick the time that suits you

PRIVATE BY DESIGN
• No account, no sign-up, no cloud
• No ads, no analytics, no tracking
• Your data stays on your iPhone, protected by iOS encryption
• Optional Face ID app lock
• Export your data anytime, or delete everything in one tap

DESIGNED FOR EVERYONE
• Soft, dreamy look in light mode and a starry night sky in dark mode
• Supports Dynamic Type, VoiceOver, Reduce Motion and Increase Contrast

Every feature is free.

Lumi helps you notice patterns in your own cycle. It is not a medical device, does not diagnose or treat any condition, and is not a form of birth control. Talk to a doctor or other health professional about medical questions.

The optional on-device AI uses Google's Gemma model, downloaded once from Hugging Face (about 2.6 GB, Wi-Fi recommended).
