Your recordings and your app data.

Recordings and audio clips

The app records and processes nighttime sound on your phone. The original recording and saved clips are stored on the phone and are not uploaded to Night & Air servers. The app may remove the original recording after exporting clips, depending on its retention setting; retained clips and derived night summaries are separate from that original. Inference results derived from those recordings are separate data and may be transmitted as described below. An optional iPhone or Android device backup setting can make saved recordings eligible for backup by your chosen device backup provider under that provider’s terms. This backup is separate from Night & Air’s servers. If you deliberately export or share a recording using your phone, the destination you choose receives it.

App information sent to Night & Air

The apps ask you to choose whether to enable non-audio data sync. When it is on, the app automatically sends supported information to Night & Air when a connection is available. This can include an app or guest identifier, device and app details, selected goals and profile, recording dates and durations, detected snoring metrics, nightly scores, check-in answers and symptoms you enter, experiments, daily actions, routines, progress and feedback. On Android, the automatic sync choice also includes generated analysis JSON, such as night graphs, timelines and detected sound patterns, and app usage events. You can turn off automatic sync and use the individual sharing controls. On iPhone, app usage and detailed analysis sharing have separate choices. These results and answers may be sensitive personal information even though they are not audio files.

We use this information to provide the app, keep your non-audio progress available, generate and update guidance, support the service, and understand how the app works. Backend processing may use submitted summaries to make wellness suggestions. The app and its scores are not a medical assessment of breathing or sleep apnea.

Health connections

If you choose to connect Apple Health or Health Connect, the app can read the categories you authorize, including sleep, heart rate, heart-rate variability, oxygen saturation or respiratory rate where available. This context is used in the app and can be included in synced night summaries if you enable non-audio sync. Check-in answers and other health context you enter yourself are covered by the app information section above. A personal data export you choose to share can also include health context.

Website email updates and beta signup

When you submit your email on the website, we store the email address you submit, your phone platform if you choose to provide it, the signup source and page, consent version, eligibility, timestamps, and limited campaign attribution such as referring page and campaign parameters. We use your email to contact you about Night & Air beta access and participation. You can ask us to stop these emails or remove your signup. The optional share button sends a general website invitation through a service you choose, or copies that invitation link; it does not include recordings or personal app results. Joining an email list is separate from installing the beta app. The site may remember first and latest visit attribution in your browser. Hosting and service providers may process ordinary connection data needed to deliver and protect the site. The site loads fonts from Fontshare. We do not sell your email address or app data for unrelated advertising.

Service providers and chosen recipients

Night & Air and the providers that host, operate, secure or back up its services may process the non-audio information described here on our behalf. We do not automatically send your progress to a partner or clinician. If you choose to export or share data, the app hands the selected file to the destination you choose, and that destination’s privacy practices apply. The optional device audio backup is handled by your device backup provider, not by Night & Air’s backend.

Your controls, retention and deletion

App settings show the sync, detailed analysis and app usage choices and let you remove saved nights. A deleted night is removed locally and its Night & Air backup and shared analysis are queued for deletion when the device reconnects. Turning off a sharing preference stops future transfers covered by that setting; it does not automatically erase information already received. You can also choose “Delete synced Night & Air data” in the app to remove the profile, check-ins, night summaries, derived metrics, detailed analysis and app usage held by the Night & Air service for that app identity. Sync pauses while deletion is pending and stays paused after completion until you choose to resume it; local nights and recordings remain. If you resume sync, saved local data can be sent again. For other deletion requests, including a website email signup or a separately managed account, contact us below.

The app can prepare a personal data export without audio for you to save or share. You can review Health permissions in your device’s health settings and control audio backup in the app and your device backup settings. Saved clips and any retained original recordings remain on your device until you remove them, the app’s retention setting removes an original after clip export, or you uninstall the app, subject to any device backup copies. Night summaries, analysis and progress stored by Night & Air remain available while needed to operate the service unless you delete a night, delete synced service data or request deletion. The in-app synced-data deletion does not remove a website email signup; that record remains while you are on the list unless you unsubscribe or request deletion. A confirmed service deletion can retain a minimal deletion marker and credential security record needed to prevent accidental restoration and support reliable retries, as well as limited information required by applicable obligations. It does not remove separately managed identities, store purchase records, copies you exported or shared, or copies held by your device backup provider. We do not currently publish a fixed period for every category; contact us for retention details or to request access, correction or deletion of your information.
