Hush — Cycle Tracker

Hush is a privacy-first menstrual cycle tracker that does one thing: keeps every byte of your data on your device. No account. No servers. No ads. No tracking SDKs. We literally cannot sell what we never collect.

WHAT'S INCLUDED (FREE)
• Period logging — start dates, end dates, optional notes
• Symptom logging — mood, energy, pain, plus quick-tap flags for cramps, bloating, headache, fatigue, tender chest, acne
• Phase detection — menstrual, follicular, ovulation, luteal
• Phase-aware ambient design that shifts color through your cycle
• Next period and ovulation forecast that refines as you log
• Custom user-defined symptom flags
• On-device symptom pattern engine — "Cramps tend to show up 2 days before your period in 5 of your last 6 cycles"
• Symptom pattern detection across cycles
• Calendar view with phase-colored history
• Light, dark, and system themes

LIFE-STAGE MODES

NOT MEDICAL ADVICE
Hush is educational. It is not a contraceptive and not a fertility diagnostic. Predictions are statistical estimates based on what you log — accuracy improves with more cycles. Always talk to a qualified healthcare provider for medical decisions.
