Luna-Cycle

Privacy-minded cycle tracking: period history, calendar, phase view, symptom logging, and insights. Wellness tool—not a medical device.

Luna is a cycle tracker that helps you log period starts, see your cycle at a glance, and build useful insights from your own history—not generic averages.

WHAT YOU CAN DO • Log period start dates and build a clear history • See cycle phases (menstrual, follicular, ovulatory, luteal) on your dashboard • View a calendar and day-by-day context for your cycle • Get range-based predictions from your logged cycles when you have enough data • Track symptoms and related notes over time • Explore insights and trends (charts and summaries) • Adjust settings and export options to match how you use the app

HOW LUNA THINKS ABOUT PREDICTIONS Forecasts use your personal history first. Broader defaults only help when you don't yet have enough cycles logged.

IMPORTANT Luna is a wellness and self-tracking tool. It is not a medical device and is not a substitute for professional medical advice, diagnosis, or treatment. Always talk to a qualified health professional for medical decisions.

ACCOUNT & SYNC Create an account to use Luna. Your data is tied to your account so you can access Luna consistently across devices when you use the same credentials.
