Why it matters

Cycle data is sensitive. KOREE Moon treats it that way.

Your cycle does not happen separately from your life.

Appointments, reminders, recurring events, symptoms, and energy all shape how a day feels. KOREE Moon brings that context into one view.

A calendar for logged days and coming days.

Understand what was recorded, what may be coming, and which days carried symptoms, flow, mood shifts, or important events.

Designed for private daily planning.

The calendar exists to support you, not to extract from you. KOREE Moon keeps intimate cycle history local-first and in your control.

Local-first privacy

No sale of cycle data. No cloud copy of your intimate logs.

KOREE Moon is built for cycle tracking, symptom logging, mood notes, and private reflection. Those logs can reveal health, emotion, relationships, routines, and life patterns, so they deserve stronger protection than ordinary app analytics.

The local-first approach keeps sensitive cycle, symptom, thought, and mood logs on your device. KOREE Moon does not sell that data, and it is not designed around third-party advertising profiles.

The result is a period and cycle tracker that can still feel useful, beautiful, and modern without turning private biology into a business asset.
