Privacy Policy Of Music Player

 Effective Date: October 31, 2026

Last Updated: October 31, 2026

Kezzlong Co ("we," "our," or "us") develops and operates the Music Player mobile application (the "App"). We respect your privacy and are committed to protecting it. This Privacy Policy outlines our data handling practices for users accessing the App on Android and iOS devices.

1. Privacy Overview: 100% On-Device Processing

Music Player is engineered as an offline-first, local audio utility:

  • No Account Required: You do not need to register, log in, or provide personal details (such as your name, email, or telephone number) to use the App.

  • On-Device Audio Playback: All audio playback, playlist curation, favorites management, queue organization, and equalizer adjustments are processed strictly on your physical device.

  • Zero Cloud Collection: We do not operate remote servers to stream, upload, catalog, or monitor your listening history or stored media files.

  • No Data Selling or Renting: We do not sell, rent, or trade your personal data, audio tracks, or listening habits to third parties or data brokers.

2. Device Permissions and Usage

The App requests only system permissions strictly required to index and play your local audio files and provide a seamless playback experience:

A. iOS (Apple App Store) Permissions

  • Media Library Access (NSAppleMusicUsageDescription): Enables the App to browse, index, and play audio and music files stored locally on your device or in your Apple Music library. Processing remains strictly on-device.

  • Background Audio (UIBackgroundModes - audio): Allows audio to continue playing smoothly while the screen is locked or while using other applications.

  • Audio Routing Detection: Used strictly to detect when headphones, Bluetooth audio devices, or external speakers are connected or disconnected to automatically pause or resume playback.

B. Android (Google Play) Permissions

  • Media Audio Storage (READ_MEDIA_AUDIO / READ_EXTERNAL_STORAGE on older OS versions): Required to scan, index, and organize audio files stored on your internal storage or SD card.

  • Foreground Service (FOREGROUND_SERVICE_MEDIA_PLAYBACK): Allows continuous audio playback in the background and renders interactive playback controls in the system notification shade.

  • Notifications (POST_NOTIFICATIONS): Used solely to display the media playback notification bar with play, pause, next, and previous controls.

3. Local Data Storage & Preferences

  • Your custom playlists, favorite tracks, playback queues, and equalizer settings are saved locally inside the App’s private sandbox directory on your device.

  • We have no access to your playlists, songs, or playback preferences.

  • Clearing application storage in your device settings or uninstalling the App permanently removes all local playlists and preferences.

4. Third-Party Services & Diagnostics

  • Diagnostics & Stability: We may access aggregated, non-personally identifiable crash traces and diagnostic metrics provided directly by platform app stores (such as Google Play Console Vitals and Apple App Store Connect Analytics) to resolve crashes and improve battery performance.

  • Advertising (If applicable): If the App includes a free ad-supported tier, third-party advertising partners (such as Google AdMob) may process standard, non-personalized device identifiers in compliance with Google Play's Ads Policy and Apple's App Tracking Transparency (ATT) framework. You can opt out of personalized tracking via your device’s system settings at any time. (Note: If the App is completely ad-free and without SDKs, this section can be simplified to: "The App contains no third-party tracking, advertising SDKs, or analytics frameworks.")

5. Account Deletion Exemption

Because Music Player operates without account registration, user profiles, or remote cloud servers, no account deletion mechanism is required under Apple App Store Guideline 5.1.1(v) or Google Play Data Deletion requirements.

6. Children's Privacy

Music Player is a general-purpose utility and does not knowingly collect personal information from children under 13 (or under 16 in the European Union).

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date.
