MusicFocus Privacy Policy

Updated November 8, 2026 · App Store versions 2.3 and 2.4 · 简体中文

MusicFocus does not require an account. The App Store release stores your scores and practice information on your device. Version 2.4 adds local voice notes, library backup and optional nearby-device collaboration. Internet rooms, a developer-hosted score cloud and remote practice monitoring are not available in this release.

1. Microphone and on-device analysis

With your permission, the app analyzes microphone input on your device for practice detection and the optional pitch display. Practice detection does not save a continuous recording or send microphone audio to the developer. Separately, when you choose the voice-note tool and start recording, the app saves the audio locally until you manage or delete it. Recording and playing a voice note pause practice detection and are not added to detected practice time.

2. Information stored on your device

The app stores imported PDF scores, handwritten and PDF annotations, fingerings, voice notes, page locations, practice sessions, reading and metronome statistics, practice notes, badges and settings in its local app storage. The developer has no dashboard through which to view these items. There is no advertising SDK, third-party analytics SDK or advertising tracking in the app.

3. Optional nearby-device collaboration

You can deliberately connect two nearby devices using Apple's local networking technology, which may use Wi-Fi and Bluetooth. Discovery can show a device display name to nearby participants. Both devices must have their own copy of the same original PDF; the app does not transfer that PDF as part of the connection.

Once you connect to a participant, the devices can exchange the score title, page count, file fingerprint and app version to check compatibility. When you request or accept synchronization or live following, annotations, fingerings, visible page/zoom position and metronome settings can be exchanged. Annotation previews may be sent as part of a synchronization request so the receiver can decide whether to apply them. These are exchanged with the connected device, not through a MusicFocus internet relay. Voice recordings and practice history are not included. A receiving participant may retain annotations you share. End the session to stop further sharing; ending a session cannot withdraw copies already received by another participant.

4. Export, sharing and backups

When you choose to export a PDF, audio file, practice information or a whole-library backup, the selected file is handed to the app, person or storage provider you choose through the system interface. Library backups include scores, annotations and saved voice notes. Standard PDF export does not embed playable voice recordings. Restore adds copies rather than replacing existing scores.

System or computer backups, iCloud Drive destinations and other sharing services are governed by your device settings and the policies of the providers you select. They are not a MusicFocus-hosted cloud backup service.

5. Permissions and deletion

You can withdraw microphone or Local Network permission in system settings. This disables the related microphone or nearby connection feature, while local score reading remains available. You can delete scores and records using the app's available controls. Removing a voice-note marker or re-recording may retain older audio locally to support undo; removing the associated score also removes its stored files. Whole-library exports include only voice recordings referenced by saved notes.

Uninstalling the app normally removes its local app data. Existing exported files, system backups and copies shared with other people must be managed separately with their respective owners or providers.

6. Children and guardians

This release does not create child accounts or upload children's practice records or recordings to the developer. Guardians should help children manage microphone permissions, device names, nearby sharing, recordings of other people and backup/export destinations.

7. Support and future versions

If you email support, we receive the message and any information you choose to send to respond to your request. If you visit our support or privacy website, ordinary network and error logs may contain your IP address and request details for website operation and security. These website visits do not give us access to your local MusicFocus library.

Internet collaboration tested in development builds is not enabled in this App Store release. If a future release introduces internet collaboration or subscription services, we will describe its data flows and permissions in an updated policy before activation.
