How claims are classified
- File observation
- A value extracted from the exact publisher-linked file, such as package, version, declared SDK or byte size. It applies to that file, not every variant.
- Publisher statement
- A feature or policy described by the developer. It is attributed and is not presented as our hands-on finding.
- General guidance
- Android or manufacturer instructions applied with model/version caveats. Device-specific paths are not invented.
- Unverified
- A missing release date, untested feature or unperformed check is identified explicitly.
Release maintenance
A release update should begin with ymusic.io and the file linked there. Record retrieval time, resolved source, bytes, SHA-256, manifest version, package, SDK and native libraries. Validate the cryptographic signature and compare signing lineage before calling a file verified for installation.
A filename is not a public version. A third-party listing date is not automatically a publisher release date. A scan result requires a dated report for the exact hash, with its limitations disclosed. No detailed change list is written without primary release notes.
Screenshots and testing
Real screenshots retain their original controls, source credit and known dates. The legacy developer previews predate the current V4 coverage; their exact builds are unknown, so they are not labeled as current V4 screens.
AI-created images illustrate migration, audio formats and file searches. They are visibly labeled as illustrations and are never used as proof of an Android procedure or app test. The founder portrait is the real image supplied by the owner.
Corrections and commercial disclosure
Corrections should change the affected statement, its source and the review date when substantive work occurs. The contact page explains the information needed and current contact status.
This implementation contains no advertisements, affiliate redirects or sponsored placements. If the owner later adds any, they should be disclosed near the relevant recommendation and reflected in the privacy policy. Rankings, review ratings and download counts are never fabricated.
