Luna: Period, Ovulation, Cycle

Stop paying $60/yr to have your intimate cycle data monetized. Luna is 100% on-device, offline & private—with free partner sharing via QR and 365-day vacation forecasts.

Luna is the private, offline-first menstrual cycle, period, and ovulation tracker designed with one unbreakable rule: your intimate health data belongs exclusively on your device.

Most cycle apps force you to create an account, upload your personal history to remote cloud servers, and monetize your habits. Luna is built differently:

◆ 100% ON-DEVICE PRIVACY & ZERO ACCOUNT REQUIRED • No email, phone number, or account creation needed to begin. • All cycle logs, symptoms, moods, and notes are encrypted locally with hardware-backed encryption. • Zero third-party ad networks, zero analytics trackers, and zero data brokers.

◆ CYCLE, PERIOD & FERTILE WINDOW FORECASTING • On-device algorithmic estimates for period start dates, fertile windows, and ovulation phases. • Adaptive cycle length tracking that learns from your natural patterns. • Clear phase breakdowns (Menstrual, Follicular, Ovulation, Luteal) with practical daily insights.

◆ DAILY SYMPTOM & WELLNESS LOGGING • Log flow intensity (Spotting, Light, Medium, Heavy) with one tap. • Track symptoms: cramps, headaches, bloating, mood swings, fatigue, breast tenderness, and skin changes. • Record wellness notes, intimacy, energy, sleep, and custom daily check-ins.

◆ ENCRYPTED CLINICIAN PDF REPORTS • Export multi-page, formatted cycle health summaries for your OB-GYN or healthcare provider. • Includes cycle variability metrics, symptom frequency distributions, and timeline charts.

◆ SECURE PARTNER SYNC • Keep your partner informed without compromising your data sovereignty. • End-to-end encrypted QR-code pairing shares only the cycle phases and dates you choose.

◆ BEAUTIFUL, CALM, INTUITIVE DESIGN • Clean Apple-inspired aesthetic free from pink clichés and intrusive popups. • Biometric App Lock (Face ID / Touch ID) and discrete app icon options.
