Privacy Policy

In short

Sleepy stores your sleep data on your iPhone and, if iCloud is turned on, syncs it through your own private iCloud account so your nights follow you across your devices. We never see it: no account is required, and no analytics or tracking is used. You are always in control of your data.

Data we collect

None. We do not collect or have access to any personal information. Everything you record in the app (bedtimes, wake times, notes, mood, fatigue ratings) is stored on your device using Apple's SwiftData framework.

Accounts and login

Sleepy does not require an account. There is no sign-up, no login, and no personal information collected. The app works fully offline.

iCloud sync

If you are signed in to iCloud, your nights are synced between your devices through your private iCloud database, using Apple's CloudKit. This data is encrypted by Apple and only accessible from your Apple Account. We cannot read it. You can turn this off anytime in iOS Settings → your name → iCloud.

Apple Health (optional)

If you enable Apple Health integration, Sleepy writes each completed sleep session to the Health app on your device, and can read sleep recorded by other sources (such as your Apple Watch) when you tap “Import nights from Health”. Imported nights are never written back to Health. This data is managed by Apple's Health framework. Sleepy never sends it to us or to anyone else. You can revoke this permission anytime in iOS Settings → Health → Data Access & Devices → Sleepy.

Vital signs (optional): if you allow it, Sleepy also reads the heart rate, heart rate variability, respiratory rate, blood oxygen, wrist temperature and breathing disturbances your Apple Watch records in Apple Health during the night. They are only shown on a night's sleep stages screen, read when you open it, and never stored or sent anywhere.

Motion (optional)

If you turn on “Suggest from my iPhone”, Sleepy reads your iPhone's motion activity on the device to spot a long still period during the night and offer to log it. This reading happens only on your iPhone and is never stored or sent anywhere. Nothing is recorded until you confirm.

Notifications

Notifications (bedtime reminders, wake reminders, wind-down reminders, weekly summary) are scheduled locally by iOS using Apple's UserNotifications framework. They are triggered entirely on your device based on the schedule you configure and never leave your phone.

Live Activities

If enabled, Live Activities display your current sleep session on the Lock Screen and Dynamic Island. They run locally on your device and are not transmitted anywhere.

Third-party services

Sleepy does not use any third-party analytics, crash reporting, advertising, or tracking SDK. The only services used are Apple's own frameworks (CloudKit, HealthKit, Core Motion, UserNotifications, ActivityKit), each of which requires your explicit permission and is governed by Apple's own privacy policy.

Data retention and deletion

Your sleep sessions are stored on your device until you delete them. You can delete individual nights from the Journal at any time (swipe or use the delete button in the night detail screen). Deleting a night removes it from all your devices. Deleting the app removes the data stored on that iPhone; nights synced to iCloud can be removed in iOS Settings → your name → iCloud → Manage Storage. Data written to Apple Health remains in your Health app and must be deleted separately from there.

Children's privacy

Sleepy is rated 4+ and does not knowingly target or collect data from children. Since no data is collected at all, no age-based restrictions apply to data processing.

Your rights

Because we do not collect or process your personal data, most data-protection rights (access, correction, deletion, portability under GDPR) are fulfilled directly by you on your device. You can export all your data at any time from Settings → Your data → Export as CSV or JSON.

Licensing

Use of Sleepy is governed by the Apple Standard End User License Agreement (EULA). Limitations of liability and warranties are as defined in that EULA.

If you are located in the EU and have concerns about how your data is handled, you also have the right to file a complaint with your national data protection authority (e.g. CNIL in France).

Changes to this policy

If this policy ever changes, the updated version will be available here and in the app. Significant changes will be announced in the app’s release notes on the App Store.
