Nimbrune — Privacy Policy

1. The short version

• Your recordings, detected clips, settings, and session history are not sent to SoftForge Digital.
• Nimbrune has no account, backend, cloud database, advertising, analytics, tracking, or external sound-analysis service.
• Recording, analysis, review, and deletion work without an internet connection.

2. Microphone and local recording

Nimbrune requests microphone access only after you choose the explained microphone-access action. Recording begins only when you start a sleep session. A low-bitrate temporary recording is stored in the app's private local container and can continue while the screen is locked or the app is in the background. Nimbrune never starts recording at launch, on a schedule, or without your action.

iOS may interrupt microphone capture for calls, alarms, route changes, or other system audio events. Nimbrune records recognized interruption gaps and resumes only when iOS permits it. Each recording stops after a maximum of 12 hours.

3. On-device sound analysis

When you choose Stop & Review, Nimbrune uses Apple's built-in Sound Analysis framework on the device to look for possible speech and snoring moments. If the 12-hour limit stops capture, the protected source remains local and analysis waits until you return to the app. Audio and classification results are never uploaded to SoftForge Digital or an external AI service.

When processing succeeds, Nimbrune keeps selected short event clips and removes the temporary full-session source. If analysis or cleanup is interrupted, the protected source or cleanup intent may remain locally so the app can offer retry or discard, or finish cleanup on a later launch.

4. Information we collect

SoftForge Digital does not collect personal information, audio, detected clips, session metadata, diagnostics, usage data, advertising identifiers, or location through Nimbrune. The app does not track you across apps or websites.

5. Local storage, sharing, and deletion

Session metadata and preferences are stored locally with SwiftData. Audio files are stored as protected files in the app's private Application Support container. Nimbrune excludes its managed audio and metadata from device backups. CloudKit is disabled.

You can delete an individual session or all local session data inside Nimbrune. Uninstalling the app removes its container according to iOS behavior. Because there is no account or backend, SoftForge Digital cannot view, recover, synchronize, export, correct, or remotely delete this local data for you.

If you deliberately share a clip through Apple's share sheet, you choose the destination. That destination handles the copy under its own terms and privacy practices. SoftForge Digital does not receive the clip through Nimbrune.

6. Network use and third parties

Nimbrune contains no advertising, analytics, remote crash-reporting, external AI, or custom networking SDK. Apple's operating-system frameworks provide microphone capture, local storage, and on-device sound classification under Apple's platform terms. Visiting this privacy page or contacting support occurs outside the app and is governed by the general SoftForge Digital website privacy policy.

7. Purpose and limitations

Nimbrune is a personal audio-review tool. Classifications can be wrong or incomplete and vary with device placement, distance, room noise, and other sounds. Nimbrune is not a medical device and does not diagnose, treat, or monitor a medical condition or measure sleep quality.

8. Changes to this policy

If Nimbrune's data practices change, this policy and the App Store privacy disclosure will be updated before the changed behavior is released. The updated date will appear on this page.
