Why it matters

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

Track your period without making your body the product.

Cycle data is sensitive. KOREE Moon is designed around the belief that period logs, symptoms, mood, and private reflections should not become advertising profiles.

See period predictions and past logs in one calm place.

Use the lunar-style calendar to understand logged days, period days, and future period windows without turning daily tracking into a clinical dashboard.

Built for dignity every day.

The app is quiet, personal, and intentionally clear: log what matters, notice patterns, and keep ownership of your intimate history.

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.
