Hush — Cycle Tracker

Now with TTC, pregnancy, and perimenopause modes, fertility treatment reminders, dark mode, and on-device pattern insights. Same privacy core.

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 • Cycle tracking (default) • TTC — emphasizes fertile window, adds BBT, ovulation tests, cervical fluid logging • Pregnancy — gestational week tracker, due date, week-by-week development blurbs • Postpartum — return-of-cycle tracking • Perimenopause — widens cycle tolerance, hot flash logging, no false "overdue" alerts

FERTILITY TREATMENT SUPPORT (TTC mode) • Custom medication reminders (you set name, dose, times — we fire the alarms) • Dose log + injection site rotation tracker (helps avoid bruising) • Trigger shot countdown • Two-week-wait countdown • Stim cycle day counter • Never gives medical advice — your RE's protocol is yours; Hush is the reminder system + journal

LEARN LIBRARY 12 in-app articles on phases, PMS vs PMDD, perimenopause, PCOS, iron deficiency, fertile windows, sleep through the cycle, birth control's effect on tracking, and more. Bundled in the app — no network calls.

DATA YOU OWN • One-tap JSON or CSV export of your entire history • iCal subscription so your cycle shows in Calendar • Doctor visit PDF — printable 6-month summary for your OB-GYN • JSON import — restore from backup, switch phones easily • One-tap full data wipe in Settings → Danger zone

DESIGNED FOR PRIVACY, NOT JUST MARKETED THAT WAY • No account, no login, no email required • Local-first storage with iOS sandboxing • No third-party SDKs except Apple's StoreKit • No crash reporter, no analytics, no attribution • Open, machine-readable JSON export so your history is portable • App Store privacy nutrition label: "Data Not Collected" — audited by Apple

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.
