Privacy Policy

SleepMumble (formerly Noctune)

Updated 13 November 2026

SleepMumble records and analyses night sounds on your phone. Your recordings and results stay in the app unless you choose to export or share them, or use a system backup described below.

What we collect

We do not automatically receive your recordings, results or settings. The app has no analytics, advertising, tracking or crash-reporting SDKs, and no account or recording-upload service. Files you choose to share and emails you send are described below.

Microphone and recordings

Where your data lives

Nights, summaries, clips and settings are stored in the app's storage on your phone. On iPhone they may be included in your iCloud Backup if you have it turned on; that backup is handled by Apple under your account, not by us. On Android they are not part of Google's backup.

To keep the free trial fair, the app stores the dates of monitoring nights and, if you choose to end the trial early, a separate marker for that choice. These contain no recordings or analysis results. Cleaning up recordings or restoring an in-app backup does not reset them. On iPhone, copies remain in this device's Keychain after the app is deleted; they do not sync to another device and are not sent to us. On Android, only these trial records are included in Google's system backup; restoration depends on your backup settings and the system.

Except for the trial records retained on iPhone as described above, deleting the app removes its local app data. Videos saved to Photos, exported files, system backups and copies sent to other apps remain in those places until you delete them there.

Things you choose to share

You control whether files leave the app. Clip sharing and saving videos are available from version 1.1.7:

The receiving app, file service or social platform handles files under its own privacy policy and the audience settings you choose. A video in Photos may sync through iCloud Photos or another backup service you enabled. Deleting a recording in SleepMumble does not remove those copies. The app does not post to social networks automatically.

Purchases

The App Store or Google Play handles payment. We do not receive your card details. The app uses store services for prices, purchase eligibility, buying, restoring purchases and supported offer-code redemption, including a purchase check in the background at launch. Recordings and analysis results are not sent with these requests.

The About page also reads the current App Store storefront to decide whether to show the mainland China filing number. The last known storefront is stored locally for offline use; device region is the fallback. This does not request location permission or send the region to us. Privacy, support, rating and filing links open external services; sharing may use the receiving app’s network connection. Recording and analysis work locally.

Email

If you write to us, we receive your email address and what you send. We use it only to reply and to improve the app, and we don't share it. Please don't attach recordings or sensitive health details.

Children

SleepMumble is not directed at children under 13. We do not knowingly collect personal information from children.

Not medical advice

SleepMumble is for personal observation of snoring. It is not a medical device and does not diagnose or treat any condition.

Changes

If this policy changes, we'll update this page and the date above. If the app ever starts collecting data, we'll say so here and in the app first.
