## What is Yawn Sleep?

How was your night? Yawn Sleep turns your sleep data into a small, delightful scene.

A soft 3D bed and the little Sleep Companion react to your personal Yawn Score. The better the night, the tidier the bed – and the more refreshed your little companion looks.

The Yawn Score is calculated directly on your device using three easy-to-understand components:

• Sleep duration
• Sleep efficiency
• Share of restorative sleep stages

Yawn Sleep works on iPhone and Apple Watch. With your explicit permission, it reads sleep stages from Apple Health.

Private by design:

• No user account
• No advertising
• No analytics or tracking SDKs
• No upload of your health data
• Processing happens entirely on your devices

The Yawn Score is Yawn Sleep’s independent estimate and is not a medical measurement. The app is not intended for diagnosis, treatment, or medical decisions.
