Privacy Policy

Last updated: 04/01/2026

Nano Songbook ("we," "our," or "us") respects your privacy. Our philosophy is simple: Your creative work belongs to you. This Privacy Policy explains how our application handles your information.

1. Data Collection

Nano Songbook is primarily an offline-first application. We do not require you to create an account, and we do not track your personal identity, location, or the content of your songs.

However, to ensure the app remains stable and bug-free, we collect anonymous technical data:

• Crash Logs: If the app crashes, we receive a report containing the code error and device state (e.g., "App crashed on Samsung S23 while opening Settings").
• Performance Data: We monitor metrics like app launch time to ensure responsiveness.

2. Third-Party Services

We use trusted third-party services to help us maintain and improve the application. These services may collect information used to identify your device for diagnostic purposes, but not your personal identity.

• Google Firebase (Crashlytics & Analytics): Used for crash reporting and basic usage analytics.

3. Permissions & Device Usage

To provide specific features, the app requires access to certain device capabilities. These permissions are used strictly for functionality:

• Local Network / Wi-Fi (Band Sync):
  Required to discover and communicate with other devices running Nano Songbook on the same Wi-Fi network. All sync data (lyrics, scroll position) is transmitted directly between devices via your local network. We do not intercept or store this data on external servers.
• Storage / Files:
  Required only when you explicitly choose to "Import" or "Export" song files or backups. We only access the specific files you select.

4. Children’s Privacy

Our Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.

5. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
