Privacy Policy

Effective date: May 17, 2026

Overview

Sharp Eleven is a music practice application for managing jazz charts, setlists, progression drills, and playback. This policy explains how the Android app handles data.

Data Stored On Your Device

Sharp Eleven stores app data locally on your device so the app can provide its practice features. This local data may include:

  • Imported or created charts and chart libraries
  • Setlists
  • Playback, drill, chart display, and theme settings
  • Temporary import links or handoff data used to complete an import

Data Collection

Sharp Eleven does not require an account and does not collect personal data on a developer server in the Android release covered by this policy. The app does not use advertising SDKs or analytics tracking in this release.

Camera

If you use QR import, Sharp Eleven may request camera access to scan a Sharp Eleven chart QR code. Camera frames are used only for QR recognition and are not stored or sent by Sharp Eleven.

Files, Links, And Sharing

Sharp Eleven can import chart files, compatible chart links, and backup text selected by you. Imported content is stored locally on your device. If you choose to share a chart, Android's share sheet may send the selected chart link to another app or service chosen by you.

Network Access

Sharp Eleven uses network access for app links and optional access to trusted third-party resources selected by you. External websites and apps may have their own privacy practices.

Notifications

Sharp Eleven may request notification permission for Android media playback controls or foreground audio playback. Notifications are not used for advertising, marketing, or tracking.

Data Deletion

You can delete locally stored app data by deleting imported charts or setlists in the app where available, clearing the app's storage in Android settings, or uninstalling the app.

Children

Sharp Eleven is a music practice tool for musicians and is not directed to children. The app does not knowingly collect personal information from children.
