1. Who we are

LynMusic manages and plays local and remote music on iPhone, iPad, Mac and Apple TV. Each description applies where the relevant platform supports the feature. The developer and personal data controller is 麦文浩, residing in mainland China. For privacy questions, contact [email protected].

We do not operate a server for centrally collecting users’ libraries, or integrate advertising, cross-app advertising tracking or additional automatic analytics uploads. Basic local features do not require a developer account. Network sources, lyrics, purchases and feedback involve the processing described below.

2. Information we process

InformationPurpose and storageLibrary and playbackSongs, albums, artists, file locations, playback history and progress, queues, favorites and playlists are stored locally for management, search, recommendations and playback restoration. Remote synchronization contacts the relevant music serviceSource configuration and credentialsServer addresses, accounts and settings you enter are saved to establish connections. Passwords and tokens managed by the credential store use the system Keychain without iCloud synchronizationLyrics, artwork and filesLyrics, artwork, cached audio, downloads and imported music, fonts, backgrounds and configurations are stored locally for playback, display and personalization. Images and audio are stored as filesPreferences and purchasesSettings and Apple-provided product, transaction and account-associated identifiers, purchase and trial dates, verification and revocation status, purchase environment and reminder records are stored locally to verify, restore and manage accessDiagnostics and feedbackCrash diagnostics are generated locally. Contact information, feedback and attachments you choose to send are used to investigate and respond, as described in section 5

Apple handles purchases and payments. We do not collect Apple Account passwords or payment card details through the app. Processing relies on the applicable basis for providing requested features, handling feedback, your valid consent or meeting legal obligations. Accepting the User Agreement does not give blanket consent to optional processing.

3. Network connections and third parties

Network requests provide recipients with necessary connection information, such as IP address and request time:

• Music sources: Connection, scanning, playback, downloads and synchronization send authentication information, song or file identifiers, queries and operations to servers you configure. Enabled background features may also make requests.
• Lyrics and artwork: Automatic matching, manual searches and configuration tests send song names, artists and configuration-dependent information such as album or duration to lyrics services you enable, and access lyrics or image addresses in the results. LrcAPI, AMLL and LRCLIB are interface presets; the configured address determines the recipient. Custom workflows may also send authentication fields or other template content you configure.
• FN Connect: When you use this connection method, the app sends the FN ID to Feiniu’s connection service to obtain connection addresses. Some connections may pass through a relay. The service provider is 广州铁刃智造技术有限公司.
• Apple: Product loading, purchases, trial claims, restoration and verification interact with Apple and may require system Apple Account sign-in. See App Store & Privacy.
• Wi-Fi transfer: On iOS/iPadOS, the transfer page enables a local receiver for browser-uploaded files, names and relative paths, without a developer relay server. The receiver stops when all transfer sessions end. Traffic is unencrypted; use a trusted network.
• External links, feedback and sharing: When you open a browser, send email or share, the destination processes connection information and your submitted content. GitHub feedback may be public. Manual update checks on tvOS also contact GitHub. See GitHub’s Privacy Statement.

Third-party services may process information outside mainland China and explain their own retention and deletion practices. Review the relevant service before enabling configurations or submitting content. We remain responsible for our own legal obligations, including any additional notices, consent and international-transfer safeguards required by law; this policy does not replace them. Disabling a source or feature stops its subsequent requests but cannot retract data already sent.

4. Permissions and controls

• Local network: Connects to music servers, shared folders and Wi-Fi transfer. Network type may determine audio quality, not your location.
• File access: Reads resources you select or import and makes changes, such as tag edits, at your direction. macOS may retain access to authorized locations.
• Photo additions: iOS/iPadOS requests add-only access when saving a lyrics image, without reading existing photos for that purpose.
