Lune: Period & Cycle Tracker

Lune is a calm, private period and cycle tracker for every woman. Know where you are in your cycle, what's coming next and what your body keeps telling you, with no account and your logs kept on your phone.

KNOWING YOUR CYCLE
Lune helps you understand your own rhythm: why your energy, sleep, skin and mood shift through the month, when your next period is likely, and what keeps repeating cycle after cycle.

TWO TAPS TO LOG
Log your period, flow, symptoms and mood in two taps, from the app or the home-screen widget. Logging is organized into Body, Mind and Life:
• Body: cramps, bloating, skin, sleep, energy, pain, cravings and fertility signs
• Mind: mood, stress, focus, brain fog, libido
• Life: workouts, food, travel and time-zone changes, conflict, massage, sauna, sex
• Medications and supplements, from painkillers to magnesium, iron, vitamin D and omega-3

A RANGE, NOT A FAKE DATE
Lune estimates your next period and ovulation from your own history and shows a window with how sure it is. Every cycle is a little different, so when one runs long, Lune follows your real day count instead of calling you "late". Log ovulation tests, basal body temperature (BBT) or cervical mucus if you like, and the estimate updates.

ONE GOOD QUESTION, MORNING AND EVENING
Instead of "how are you?", Lune asks one small question that fits your cycle phase, answerable in two taps from the notification.

SEE YOUR PATTERNS
Symptoms by cycle phase, energy and sleep across the cycle, cycle length over time, and what you ate or did yesterday next to how you felt today. Your symptoms sit on top of an educational hormone curve, so the phases make sense.

ASK LUNE (PRO)
A short read on where you are in your cycle, and answers to your questions, up to 5 a day, drawn from your own logs. Observations, never diagnoses.

HOME-SCREEN WIDGETS
Cycle day, phase and next period at a glance, with one-tap logging. Prefer discretion? Pick a soft ring or a moon style that only you can read.

HEALTH CONNECT
Import periods, basal body temperature, ovulation tests, workouts and steps from apps and wearables that write to Health Connect. Lune only reads; it never writes to Health Connect.

HOW CLOSE LUNE HAS BEEN
After each period, Lune shows how close its estimate was, and uses that record to widen or tighten your next window. Log illness, travel or stress and the window explains why it moved.

PRIVATE BY DESIGN
• No account. Your logs are stored on your phone.
• Nothing you log is ever sent for analytics or advertising.
• Ask Lune sends a short summary only when you ask, and nothing is stored on the way.
• Export to CSV or JSON, back up, or delete everything at any time.

IMPORTANT
Lune is a tracking app, not a medical device. It does not diagnose, treat, cure or prevent any condition, and it is not a method of contraception. Predictions are estimates from your own data. Talk to a doctor or other healthcare professional about anything that worries you; Lune lists the signs worth taking to one.
