Privacy Policy

Last updated: January 1, 2026

Our Commitment to Privacy

At Optimiz, we believe your sleep data is deeply personal and belongs to you alone. This Privacy Policy explains how we handle information when you use our mobile application. We've designed Optimiz with privacy at its core—your sleep data stays on your device and is never uploaded to our servers.

Information We Collect

Data Stored Locally on Your Device

The following data is processed and stored exclusively on your device:

  • Sleep tracking data (sleep stages, duration, quality scores)
  • Audio analysis data (for sleep stage detection and noise canceling)
  • Movement data (from device accelerometer)
  • Your app preferences and settings
  • Sleep history and trends

Important: Audio recordings are processed in real-time and are never stored. We only retain analyzed data points, not raw audio.

Data We May Receive

If you contact us for support or enable optional features:

  • Email address (if you contact support)
  • Device type and app version (for troubleshooting)
  • Anonymous crash reports (opt-in only)

How We Use Information

  • To provide and improve the Optimiz sleep tracking experience
  • To respond to support requests
  • To fix bugs and improve app performance
  • To develop new features (using only anonymized, aggregated data)

Data Sharing

We do not sell, rent, or share your personal data with third parties. Your sleep data remains on your device. We may share anonymized, aggregated statistics for research purposes, but this data can never be traced back to you.

Data Security

Your sleep data is encrypted on your device using industry-standard encryption. Since data stays on your device, you maintain full control. We recommend keeping your device secured with a passcode or biometric authentication.

Your Rights

  • Access: View all your sleep data within the app
  • Delete: Clear all data by uninstalling the app or using the in-app data reset option
  • Export: Export your sleep data in standard formats
  • Opt-out: Disable optional analytics at any time in settings

Children's Privacy

Optimiz is not intended for children under 13. We do not knowingly collect data from children. If you believe a child has provided us with personal information, please contact us.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes through the app or by email. Continued use of Optimiz after changes constitutes acceptance of the updated policy.
