## What is PrivateCycle?

PrivateCycle is a privacy-first period, cycle, and ovulation tracker that keeps 100% of your health data on your device. No account. No sign-up. No ads. No telemetry. No third-party data sharing — ever. Your body is your business.

Log your period, symptoms, mood, and fertility signals in seconds, and get clear, honest predictions for your next period, fertile window, and ovulation — all computed locally on your iPhone.

WHY PRIVATECYCLE
• Local-first: core tracking, predictions, and insights work with no internet and no account.
• Your entries are stored in an encrypted database on your device (AES-256).
• No ads. No data sale. No hidden trackers or third-party SDKs.
• Transparent predictions that are honest about uncertainty instead of faking precision.
• Core tracking is free, forever.

TRACK WHAT MATTERS
• Period flow — light, medium, heavy, clots — with start and end logging.
• Symptoms: cramps, headache, tender breasts, bloating, fatigue, acne, backache, nausea, hot flashes and more.
• Mood and feelings, energy, sleep, cravings, digestion.
• Discharge, sexual activity and drive.
• Measurements: basal body temperature, weight, water, sleep hours, LH and pregnancy tests.

HONEST PREDICTIONS
• Next period date with a prediction window, not a false exact day.
• Fertile window and estimated ovulation day.
• Current cycle phase and a plain-language confidence level.
• Irregular cycles and late periods are explained, never silently guessed away.

SEE YOUR PATTERNS
• A full cycle calendar with an at-a-glance legend.
• Cycle history and averages.
• Insights into how your symptoms move with your cycle.

MODES FOR EVERY LIFE STAGE
• Cycle tracking.
• Trying to conceive.
• Pregnancy — gestational age, due-date countdown, weekly summary.
• Perimenopause — symptom logging and an irregularity view.

PRIVACY BUILT IN, NOT BOLTED ON
• Your data never leaves your device by default.
• App Lock with Face ID or Touch ID keeps your entries yours.
• Full data ownership: export to JSON, CSV or plain text, passphrase-protected local backup and restore, and one-tap delete-everything.
• Reminders are scheduled locally on your device.

PLUS — ONE-TIME UNLOCK, NO SUBSCRIPTION
Upgrade once inside the app to unlock:
• An on-device AI health assistant — private answers, with nothing leaving your phone.
• Advanced insights: your body's patterns, symptom forecasting, and lifestyle-to-symptom correlations.
• A clinician report — a formatted, date-range summary to bring to your doctor.
• The full pregnancy experience: week-by-week development, body changes, daily tips, kick counter, contraction timer, appointments and checklist.
• Full perimenopause: symptom-burden view, timeline and milestones.
• Advanced reminders.
No ads, no subscription, and the same privacy guarantees. Buy once, keep it.
