Sound is analyzed on your device. Playable raw audio is not saved or uploaded by default. You can stop monitoring and delete one night or all local data at any time.
Information we process
Microphone input is processed in device memory only after you start monitoring, to calculate relative sound level and possible snoring features.
Structured results include session times, sound-analysis samples, possible snoring statistics, partner disturbance marks, and improvement-experiment status.
This version does not require an account and does not collect your name, phone number, or email address.
Storage and transmission
Playable raw audio is not saved by default. This version does not upload audio, video, or monitoring results to our servers.
Structured results stay in the app’s private local storage. Up to 30 recent sessions are retained, and Android system backup is disabled.
You can permanently delete one night or all local records. Uninstalling the app deletes its private local data.
Permissions
Microphone: on-device sound analysis during a session you explicitly start.
Notifications: ongoing monitoring status and quick actions to mark a disturbance or stop monitoring.
Foreground service and wake lock: continuation of a user-started session while the screen is off.
Consent and acceptable use
Before monitoring, make sure your bed partner and other people near the phone know and agree.
Never use the app for secret monitoring or share information about another person without permission.
Health information
Possible snoring and risk education are observations only. This app is not a medical device and does not diagnose, treat, cure, or prevent any disease.
Possible snoring observations cannot diagnose sleep apnea. Consult a qualified healthcare professional for medical advice, diagnosis, or treatment—especially for choking awakenings, marked daytime sleepiness, or morning headaches.
Third-party services and children
This version contains no advertising, analytics, cloud-sync, or third-party sign-in SDK.
The app is intended for adults and their consenting partners. It is not directed to children and does not knowingly collect children’s personal information.
