Last updated: April 12, 2026

1. Introduction

Somna (“we,” “our,” or “us”) operates a sleep intelligence web application that connects to your Oura Ring to help you understand and reduce snoring. This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our service.

2. Information We Collect

We collect the following categories of information:

2.1 Account Information

When you create an account, we collect your email address and password (stored securely via Supabase Auth).

2.2 Oura Ring Data

With your explicit authorization via OAuth 2.0, we access the following data from your Oura Ring account: blood oxygen saturation (SpO₂), heart rate variability (HRV), respiratory rate, resting heart rate, sleep stages and duration, sleep efficiency, and body temperature. This data is used solely to generate your sleep analysis and morning reports.

2.3 Self-Reported Data

Through the evening check-in feature, you may voluntarily provide: meal timing and type, alcohol consumption, stress level, nasal congestion level, and planned sleep position.

2.4 AI Chat Data

If you use the AI Sleep Coach feature, your conversation messages are stored to provide context for future interactions.

3. How We Use Your Information

We use your information to:

  • Generate personalized morning reports identifying snoring root causes
  • Calculate your predictive snore risk score
  • Provide AI-powered sleep coaching based on your biometric data
  • Identify clinical patterns that may warrant professional medical evaluation
  • Improve our algorithms and service quality

We do not sell your personal data to third parties. We do not use your data for advertising purposes.

4. Data Storage and Security

Your data is stored in Supabase (PostgreSQL) hosted in Canada. We implement the following security measures:

  • Row Level Security (RLS) on all database tables, ensuring you can only access your own data
  • Encrypted storage of Oura API access and refresh tokens
  • HTTPS encryption for all data in transit
  • Authentication required for all API endpoints handling user data

5. Third-Party Services

We integrate with the following third-party services:

  • Oura (ouraring.com) — We access your Oura Ring data via their API with your explicit OAuth authorization. Oura's own privacy policy governs their data collection.
  • Anthropic (Claude API) — We send anonymized biometric data summaries to generate AI-powered reports and chat responses. No personally identifiable information is included in AI prompts.
  • Supabase — Our database and authentication provider, hosted in Canada.
  • Vercel — Our hosting provider for the web application.

6. Your Rights

You have the right to:

  • Access your personal data at any time through the application
  • Request a copy of all data we hold about you
  • Request deletion of your account and all associated data
  • Revoke Oura Ring access at any time through your Oura account settings
  • Opt out of AI-generated reports (template-based reports will be used instead)

7. Data Retention

We retain your data for as long as your account is active. Upon account deletion, all personal data, biometric records, check-in history, reports, and chat messages are permanently deleted within 30 days.

8. Medical Disclaimer

Somna is a wellness monitoring tool, not a medical device. It is not intended to diagnose, treat, cure, or prevent any disease or medical condition. Our reports and AI recommendations do not constitute medical advice. If you are concerned about sleep apnea or any sleep disorder, please consult a qualified healthcare professional.

9. Children's Privacy
