Privacy Policy

Last updated: September 24, 2026

Sleep Island ("we") values your privacy. This policy explains how we collect, use, and protect your information.

1. Information Collection

Sleep Island collects the following information to provide our services:

• Sleep data: Sleep time, wake time, deep/light sleep stages. Stored locally on your device.
• Audio data: Audio clips recorded during snore detection, processed and stored locally only.
• Usage data: Anonymous app usage statistics used to improve the product experience.

Website analytics

We record page views, user-initiated sound playback, App Store and Google Play button clicks, and clicks into the app section to improve this website. Records contain the page, language, button position, device category and source category. We do not store IP addresses, full referrer URLs, recordings or health data in these analytics, and set no analytics cookies. A random page identifier groups events within one page visit; it does not identify you across pages. Event details are retained for 90 days. We do not send these events when your browser enables Do Not Track or Global Privacy Control.

2. Data Usage

We only use your data for:

• Providing sleep analysis and snore detection services
• Generating personalized sleep recommendations
• Improving app performance and user experience

3. Data Storage & Security

Your sleep data and audio recordings are stored locally on your device. We do not upload your personal health data to cloud servers. We use industry-standard security measures to protect data transmission.

4. Third-Party Services

We do not use third-party advertising SDKs. We may use anonymous crash reporting services to improve app stability.

5. Your Rights

You can delete all personal data within the app at any time. For assistance, contact contact@sleepisland.org.
