Privacy Policy

1. Introduction

Somna is committed to protecting your privacy. This Privacy Policy explains how our mobile application handles your data.

2. Data Collection and Usage

Somna is a local-first application. Your sleep logs, settings, and personal data are stored locally on your device.

Somna does not operate its own analytics server and does not sell your personal data.

Some optional third-party services may process limited technical data when you use related features: Google Play Billing and RevenueCat for Pro purchases, Google AdMob for banner ads shown to free users, the AI Coach provider for AI responses, and Google Drive for optional cloud backup.

3. Purchases and Advertising

Somna offers an optional Pro upgrade through Google Play. Purchases are processed by Google Play and entitlement status is managed through RevenueCat. We do not receive or store your full payment card details.

Free users may see banner ads served by Google AdMob. Pro users do not request or display ads.

To serve ads, measure them and prevent fraud, the Google Mobile Ads SDK collects and shares with Google your device's advertising ID, IP address (approximate location), ad interactions and diagnostic information. See How Google uses information from sites or apps that use its services.

4. Google Drive Data (Cloud Sync)

Somna offers an optional Pro feature to backup and sync your data using Google Drive.

Information we access:

If you choose to use this feature, Somna will request access to your Google Drive via the official Google Sign-In.

How we use your data:

• Storage: We upload a backup file (`somna_sleep_logs_backup.json`) to a hidden application data folder (`appDataFolder`) in your Google Drive.
• Restoration: We download this specific file to restore your sleep data across devices.
• Privacy: We cannot see or access any other files in your Google Drive. The permission is restricted strictly to files created by Somna.

Data Safety:

Your data is transferred directly between your device and Google's servers using secure encryption (HTTPS). We do not store your sleep data on our own servers.

5. AI Coach

If you use the Pro AI Coach feature, your prompt and relevant sleep-log summary may be sent to the AI service to generate a response. Do not enter emergency medical information or information you do not want processed by the AI provider.

Our AI relay server forwards each request to the AI provider and does not store your messages or sleep logs.

6. Your Choices and Data Deletion

• Sleep logs on your device: Delete individual logs in History. To delete all Somna data on your device, uninstall the app or clear its storage in Android Settings > Apps > Somna > Storage.
• Google Drive backup: Disconnecting Google Drive in Somna does not delete the backup. To delete it, open Google Drive, go to Settings > Manage apps > Somna > Options and choose Delete hidden app data.
• Advertising ID: Reset or delete it in Android Settings > Privacy > Ads.
• Purchase records and anything else: Email tamariskx@gmail.com with the subject "Delete my data". Include your Google Play order ID (it starts with "GPA") if you bought Pro. We will delete the related records held by Somna and RevenueCat within 30 days. Google Play keeps its own order records under Google's policies.
