LunaRest Privacy Policy

Effective Date: May 13, 2026 Last Updated: September 1, 2026

1. Introduction

Welcome to LunaRest ("we," "our," or "us"). LunaRest is a sleep wellness application designed to help you track, understand, and improve your sleep. We are committed to protecting your privacy and being transparent about how your information is used.

This Privacy Policy explains what data we collect, how we use it, and your rights as a user. By using LunaRest, you agree to the practices described in this policy.

2. Information We Collect

2.1 Information You Provide

• Sleep data — bedtime, wake time, sleep duration, sleep quality ratings, and notes you enter manually
• Health assessment answers — responses to our sleep health onboarding questionnaire (chronotype, stress level, sleep disruptors, etc.)
• CBT-I program progress — which lessons you have completed and your reflection answers
• Night recordings — short audio clips saved automatically around real sound events during Auto Sleep Tracking (snoring, coughing, sleep talking), stored locally on your device only
• Coach chat conversations — if you use the Pro AI Coach chat, your messages and the coach's replies are stored locally on your device so your conversation history persists between sessions
• Settings preferences — language, target sleep hours, notification preferences, and your iCloud backup choice (see §2.5)

2.2 Information Collected Automatically

• Device information — device type, operating system version (used only for app compatibility)

2.3 Apple Health Data (Optional)

If you choose to connect Apple Health, LunaRest may:

• Read your sleep history, and, if you wear an Apple Watch to bed, overnight vitals including heart rate, resting heart rate, heart rate variability (HRV), respiratory rate, blood oxygen, and wrist temperature (on Apple Watch models that support it)
