## Description

Built by a gynaecologist, not an ad network. Your cycle data never leaves your phone — no account, no cloud, no tracking.

Cycle Tracker is a comprehensive menstrual health app designed by Ricardo Santos, MD, PhD — a gynaecologist and reproductive medicine specialist. Clinical rigour meets intuitive design to help you truly understand your body.

 DETAILED CYCLE TRACKING
• Log menstruation, spotting, cervical mucus, basal body temperature, LH surge tests, and intercourse
• Visual calendar with colour-coded events and predicted fertile windows
• Track 15+ physical and emotional symptoms with light, moderate, and heavy severity levels
• Customisable cycle and period length settings

 PREDICTIONS & ANALYTICS
• Predictions calculated from your own cycle history, not population averages
• Cycle regularity assessment and length trend analysis
• Historical pattern recognition across multiple cycles
• Personalised insights based on your unique data

 PRIVACY FIRST
• All data stored locally on your device — never shared, never uploaded
• Optional biometric authentication (Face ID / Touch ID)
• No advertising, no data collection, no third-party access

 DESIGNED FOR EVERYONE
• Available in English, Portuguese, and French

Cycle Tracker was developed with the clinical care your reproductive health deserves. Whether you are monitoring your cycle, planning a pregnancy, or simply learning your body's patterns — this app gives you the tools to do it right.

IMPORTANT
Cycle Tracker is a tracking and educational tool, not a medical device. Predictions are statistical estimates calculated from the cycle history you enter — they are not a diagnosis and must not be used as a method of contraception or to rule out pregnancy. Always speak to your doctor before making any medical decision.
