About Clue

What Clue Does

Clue is a period and cycle tracker app that helps you understand your body through science-based, data-driven tracking. It predicts your period, PMS, ovulation, and fertile windows so you can anticipate symptoms before they start and plan accordingly.

Problem It Solves

Many cycle trackers lack scientific rigor or compromise user privacy. Clue solves both: it uses evidence-based methods to analyze cycle patterns while never selling or sharing your health data, protected by strict EU privacy laws.

Who It Is For

Clue is designed for anyone with a menstrual cycle, from teens experiencing their first period to women approaching perimenopause. It is ideal for those who want reliable cycle predictions, symptom tracking, and fertility awareness without compromising data privacy. It is not intended as a medical diagnostic tool or a contraception-only app.

Real Use Cases
