Privacy Policy

Last updated: May 25, 2026 · Effective for Sleep Debt iOS v1.0 and later.

Sleep Debt is committed to protecting your privacy. This policy explains how we handle your data.

Data Collection

Sleep Debt only accesses sleep data from Apple Health that you explicitly authorize. This includes sleep duration, bedtime, wake time, and (when available) sleep stages. We do not collect personally identifying information, contact information, location, advertising identifiers, or any other category of data outside of the Apple Health sleep samples you choose to share.

Data Storage

All your sleep data is processed and stored locally on your device. We do not upload, transmit, sync, or store your data on any external servers. Your data never leaves your device. The app does not maintain any user account.

Third Parties

We do not share, sell, or transfer your data to any third parties. The app contains no advertising, no analytics SDK, no third-party tracking framework, and no crash-reporting SDK.

Notifications

If you enable Bedtime Reminder, Sleep Debt schedules a local notification through iOS’s built-in UserNotifications framework. No notification content or scheduling data is sent to any server.

Your Rights

You can revoke Apple Health data access at any time through iOS Settings → Health → Data Access & Devices → Sleep Debt. You can revoke notification access through iOS Settings → Notifications → Sleep Debt. Deleting the app removes all locally stored data permanently and immediately.

Children

Sleep Debt is rated 4+ and contains no objectionable content. It does not knowingly collect any personal information from children.

Changes to This Policy

If we materially change how the app handles data, we will update this page and the date above. Because all processing remains on-device, we do not anticipate changes that would broaden data collection.
