Terms of Service

By downloading, installing, accessing, or using Ghost Music Player ("the Application"), provided by SDDEV ("Developer", "we", "us", or "our"), you acknowledge and agree to be bound by these Terms of Service. If you disagree with any part of these terms, do not install or use the Application.

These terms apply across all supported Android platforms including smartwatches (Wear OS), smartphones, foldables, tablets, and Android TV.

We grant you a personal, non-exclusive, revocable, non-transferable, limited license to run Ghost Music Player solely for personal, non-commercial playback, vocal practice, and audio processing of legally acquired audio files on your compatible Android devices.

You agree not to reverse engineer or extract standalone proprietary neural weights, sublicense the software, or bypass digital rights management protections on restricted audio sources.

Ghost Music Player is built upon an uncompromising offline-first foundation:

• Zero Cloud Telemetry: No audio tracks, vocal recordings, playback statistics, or listening habits are ever monitored or transmitted to remote servers.
• On-Device Audio DSP: 10-band equalization, Bass Boost, 3D Virtualization, and waveform rendering operate entirely inside local Android audio hardware and memory.
• No Remote User Account: Playlists, favorites, and metadata caches are stored exclusively on your device via local ObjectBox storage.

You retain 100% ownership over your personal voice recordings, created playlists, and trimmed ringtone files.

The Application includes an offline AI vocal stem separator powered by the UVR-MDX-Net neural model running locally via ONNX Runtime:

• Hardware Processing: Audio separation runs 100% locally on your device's CPU/NPU. No audio stream is ever sent to a cloud processing farm.
• Personal Use: Isolated vocal and instrumental tracks are intended solely for personal rehearsal, practice, and non-commercial study.

Ghost Music Player requests microphone access strictly for the optional Sing & Rehearsal karaoke studio:

• Microphone audio is monitored and recorded solely when you explicitly tap the record button.
• Rehearsal recordings are saved strictly into your private local application storage or chosen music folder.
• Microphone access is never activated in the background or during normal playback.

Synchronized lyrics and album artwork may be retrieved on demand using community-driven APIs such as LRCLIB:

• Lyrics queries send only song title and artist tags to match time-synced lyrics text.
• Offline translation of lyrics is executed on-device using local Google ML Kit Translation models.
• LRCLIB is an independent community service and the Developer does not warrant the permanent availability or accuracy of crowd-sourced lyrics.

Ghost Music Player provides core media playback without mandatory subscriptions. Any optional premium features, developer tips, or pro upgrades are processed exclusively through Google Play Billing:

• No Financial Credentials Collected: All financial transactions are managed entirely by Google Play under your personal Google account. We do not receive or store payment card details, bank information, or billing statements.
• Google Play Terms Apply: For billing inquiries, dispute resolutions, and refund evaluations, please refer to Google Play's Refund Policy.

Ghost Music Player is provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind. The Developer is not liable for device audio driver incompatibilities, playback latency on low-end hardware, or third-party copyright claims arising from your use of personal media files.

We reserve the right to amend these Terms of Service as necessary. Changes become effective upon publication on this site with an updated date stamp. Your continued use of the Application signifies acceptance of revised terms.
