## What is Daya?

Understand your menstrual cycle with Daya.
Track your period, symptoms and daily changes in one simple app. No account, no ads and no subscription.

TRACK YOUR CYCLE
Log the start and end of your period and keep a personal history. See your cycle phases and estimated dates for your next period.

PLAN AHEAD
Use your menstrual calendar to keep a clear view of upcoming dates and prepare for your next period.

UNDERSTAND YOUR FERTILE WINDOW
View estimated ovulation and fertile days to better understand how your cycle changes throughout the month.

KEEP A SYMPTOM DIARY
Your cycle is about more than your period. Record what you experience each day:
• Pain and cramps
• Mood and energy
• Fatigue and sleep changes
• Acne, bloating and headaches
• Menstrual flow
• Vaginal discharge and spotting
• PMS-related symptoms

Review your entries over time and get to know your own patterns.

YOUR HISTORY, IN ONE PLACE
Find your calendar, previous periods, cycle lengths, estimated fertile window, symptoms and trends without switching between apps. Set local reminders for the moments you want to remember.

TRACKING THAT FITS YOUR BODY
Every cycle is different. Regular entries help you build a personal record and understand changes over time, including irregular cycles.

Daya is a tracking and wellbeing tool. Period, ovulation and fertility predictions are estimates. They are not medical advice and must not be used as contraception. Daya does not diagnose medical conditions.

FREE ESSENTIALS, OPTIONAL SUPPORT
Daya is free to download. Essential cycle tracking, calendar, journal, symptom and history features are available without a subscription.

Daya may offer optional in-app purchases to support the app and activate the Lifetime Founder Pass. These are one-time purchases, not auto-renewing subscriptions. Prices are shown in the app and on the App Store before you confirm a purchase. You can restore purchases from Settings.

PRIVACY
Daya works without an account, advertising or ad tracking. Your cycle data stays on your iPhone. If you choose to send feedback, only the message you submit is sent.
