PagePilot Privacy Policy

Last updated: June 15, 2026

Katsushi Kawato ("we", "us") provides this Privacy Policy for the sheet-music viewer app "PagePilot" (the "App"), describing how the App handles your information.

1. Information We Collect

The App does not collect any personal information such as your name, email address, account credentials, or location. All data handled by the App — scores, setlists, annotations, and settings — is stored only on your device. None of this data is transmitted to or stored on any external server, including ours.

2. Use of Device Features

The App uses the following device features solely for the purposes described below. We do not collect, retain, or share any information obtained through these features.

  • Camera: Used only to scan a QR code shown on another device in order to receive shared scores. No photos or videos are taken or stored.
  • Bluetooth: Used to connect to MIDI instruments and to the DAW Conductor accessory.
  • Local Network (Wi-Fi): Used to transfer scores and setlists directly between your own devices. Data is exchanged only between devices on the same network and never passes through an external server.

3. Communication with External Services

The App connects to the font's distribution source (GitHub, github.com) in order to retrieve display fonts. This connection is used solely to download font files and does not transmit any personally identifying information such as your name or email address. GitHub's handling of access logs (such as IP addresses) recorded as part of this connection is governed by GitHub's own privacy policy.

Apart from the above, the App does not communicate with any external server. If you choose to share or store score data through another service (such as a cloud storage provider), that handling is governed by that service's own terms and privacy policy and is outside the scope of this Policy. How the App handles information when you choose to share diagnostic information is described in Section 4.

4. Sharing Diagnostic Information (Optional)

The App includes a feature that lets you share diagnostic information to help investigate problems. It runs only when you explicitly choose to use it in the settings screen; the App never sends this information automatically.

  • A diagnostic report may include, for example, the app version, your device's OS type and version, and internal runtime logs (records of screen transitions and processing, internal identifiers, and error information). It does not include the contents of your scores, setlists, or text, nor file names or song titles.
  • You choose the destination through your device's share feature. Please review the contents before you share, and choose where to send it. We receive a report only if you send it to us, and we use it solely to investigate problems.

5. Analytics, Advertising, and Tracking

The App performs no usage analytics, serves no advertising, and does not allow any third-party tracking. It does not access the advertising identifier (IDFA) or perform cross-app tracking.

6. Children's Privacy

Because the App collects no personal information, it is safe to use for users of all ages.

7. Use from Outside Japan

Because the App collects no personal data, the same handling applies regardless of your country or region. Even where regulations such as the EU General Data Protection Regulation (GDPR) apply, there is no personal data that we process or store.

8. Changes to This Policy

We may revise this Policy as needed. If we make a material change, we will announce it on this page.

9. Contact
