Privacy Policy

Overview

SleepOz (“app”, “we”) provides sleep tracking and snoring analysis. This policy explains what data we collect, how we use it, and your rights.

Data controller: SleepOz. Contact: ozkaptanhakan@gmail.com

Data We Collect

Account: email, display name (optional), auth session.

Sleep sessions: start/end time, duration, quality score, stage estimates, snore count.

Sound events (metadata): event type, intensity, timestamp — not raw audio.

App preferences: language, dark mode, alarm, notifications.

Permission flags: microphone and notification grant status.

Data We Do Not Collect

Raw overnight audio is never uploaded to our servers or Supabase Storage.

Location data is not collected.

No advertising IDs or third-party ad tracking.

The app is not directed at children under 13; we do not knowingly collect children’s data.

Microphone Usage

The microphone is used only when you start an active sleep session via “Start Sleep”.

Audio is analyzed on-device in real time to detect snoring and similar events.

No microphone access outside active sessions you initiate.

System permission dialogs are shown per App Store / Play Store guidelines.

Apple Health (HealthKit)

On iOS, SleepOz optionally uses the Apple HealthKit API.

When enabled under Settings > Apple Health (HealthKit), start and end times from completed sleep sessions are written to the Apple Health app as sleep analysis.

We do not read other health data through HealthKit; only sleep duration is shared.

This feature is optional; no HealthKit data is written when it is turned off.

Android Health Connect

On Android, SleepOz can optionally write sleep duration to Health Connect (requires a dev client/build with the native module).

When enabled under Settings > Health Connect, start and end times from completed sessions are written.

Raw audio and event recordings are not sent to Health Connect.

No Health Connect data is written when the feature is off.

Local Audio Recordings

Full-night recordings stay on your phone in the app sandbox (sleep-recordings/ folder).

View the file path in-app and delete recordings individually or in bulk.

Cloud file storage (Storage) is not used.

How We Use Data

Third-Party Sharing

Infrastructure: Supabase (database, auth) over TLS.

Data Retention

Security
