Period Tracker – Private Cycle

Track your period, cycle, and symptoms completely offline — no account, no cloud sync, no subscription. Your menstrual cycle data stays on your phone, private and fully yours from day one.

📅 ACCURATE PERIOD & CYCLE TRACKING
Log your period start and end dates, flow intensity, cervical mucus, basal body temperature, mood, energy, and symptoms every day. The cycle tracker builds a personal model from your actual logged history — whether your menstrual cycle runs 21 days or 45 days — and delivers fertile window predictions and period forecasts calibrated to your real rhythm, not a textbook average. Every logged cycle sharpens the predictions automatically.

🔒 COMPLETELY OFFLINE — YOUR DATA NEVER LEAVES YOUR DEVICE
No sign-up screen. No email address. No profile creation. Open the app in under ten seconds. Every piece of menstrual data lives only on your device. No server receives your cycle dates, no cloud backup uploads your symptoms, no third party accesses your reproductive health records. For women who need true privacy — for legal, personal, or safety reasons — this is the only period tracker built that way from the ground up.

💊 PILL REMINDER & BIRTH CONTROL TRACKER
Never miss a birth control pill again. Set a daily pill reminder at the time that works for you — whether you take the combined pill, mini pill, or any other oral contraceptive. The pill tracker logs each dose, alerts you when it's time, and lets you note any missed pills so the cycle tracker can account for hormonal changes in your predictions. Pair your contraceptive pill reminder with your period tracker for a complete picture of your reproductive health.

🩺 PCOS, ENDOMETRIOSIS, PMDD & IRREGULAR CYCLES
Mainstream period trackers assume a 28-day cycle. This one does not. If your menstrual cycle varies by weeks rather than days — common with PCOS, endometriosis, PMDD, postpartum recovery, perimenopause, or hormonal imbalances — the tracker learns your actual range and shows predictions as a window of days, not a fixed date. After three to four cycles, the pattern engine surfaces correlations between symptoms, cycle phase, and physical experience. Women with PCOS, endometriosis, and PMDD have brought these logged patterns to their OB-GYN and received diagnoses they had been seeking for years.

🌙 CYCLE PHASES, MOON CYCLE & HORMONE AWARENESS
Your menstrual cycle has four distinct phases. Follicular phase: estrogen rises, energy builds, cognitive performance peaks. Ovulatory phase: your fertile window opens, social confidence and physical strength spike. Luteal phase: progesterone takes over, PMS and PMDD symptoms may begin. Menstrual phase: flow tracking, cramp management, renewal. Some users track alongside the lunar cycle, noting how their personal monthly rhythm aligns with the moon cycle across seasons.

📊 DEEP SYMPTOM & MOOD TRACKING
Track PMS and PMDD symptoms, cramps, bloating, headaches, breast tenderness, menstrual acne, sleep quality, stress, anxiety, libido, basal body temperature, and cervical mucus changes across every phase. PMDD users can log mood severity daily and identify the specific luteal phase window where dysphoric symptoms peak — data that is clinically relevant and often diagnostic at a gynecologist visit.

🩺 DOCTOR-READY HEALTH REPORT
Generate a complete cycle history — period dates, lengths, symptoms, and charts — formatted for your OB-GYN, endocrinologist, or fertility specialist. No screenshots or handwritten notes needed.

🤫 DISCREET MODE
Change the app name and icon to a neutral calendar appearance in settings. Add a PIN or fingerprint lock. Your period and cycle data stays private on any shared device or in any environment where visibility matters.

🌸 PERIMENOPAUSE & MENOPAUSE
Track irregular cycles, hot flashes, night sweats, sleep disruption, and mood changes through perimenopause and menopause. Handles cycle gaps of 60, 90, or 120+ days without assuming pregnancy.

Your cycle. Your data. Your phone. Always.
