01Introduction
UNIFY Hi-Res Music Player Pro (also called UNIFY Music) is an Android music player, equalizer and audio-processing application operated by an independent developer in Vietnam.
UNIFY Music can play audio stored on the device and can connect to music controlled by the user in personal Google Drive, Dropbox, WebDAV and SMB2/SMB3 or NAS locations. It does not provide a public commercial streaming catalog.
The app also contains an optional online Community area. The private connected-storage player and the public Community are separate features.
Private-library principle: connecting a cloud folder or private server does not automatically publish, share or upload the user's music to Community.
02Age requirements
13+
Core player and connected storage
Users must be at least 13 to use local playback, equalizer tools and private cloud/server playback. Provider account rules and any higher local age requirement still apply.
Community is strictly 16+. Users aged 13–15 may use the core player and private connected-storage functions, but cannot use Community accounts, posts, comments, follows, likes, favorites, reposts, creator subscriptions or other Community activity.
Users under 13 must not use UNIFY Music. No parental-consent exception permits a user under 16 to participate in Community.
03Local music and Android permissions
| Permission or data | Purpose |
|---|
| Music and audio files | Scan, organize and play supported files stored on the phone or SD card; read path, filename, title, artist, album, genre, duration, lyrics, tags and embedded artwork. |
| Microphone or audio-analysis access | Analyze sound waves for supported visualizers or audio processing. UNIFY Music does not use this permission to create or store voice recordings. |
| Notifications and foreground playback | Show playback controls, equalizer status, timers and supported account or Community activity. |
| Exact alarms | Run a Wake Timer at the time selected by the user. |
| Battery-optimization settings | Help supported playback or spatial-audio functions continue in the background. Changing this setting is optional. |
| Local app storage | Store playlists, queue state, lyrics, notes, metadata edits, artwork references, profiles, presets, source indexes, cache and editor projects. |
| Internet and network access | Connect to user-selected cloud accounts, WebDAV servers, SMB/NAS shares, Community services, billing, updates, analytics and advertising where enabled. |
| Google Play Billing | Validate trials, subscriptions, one-time purchases and Premium entitlement without receiving full card or bank details. |
Local audio is processed on the device for playback, EQ, bass, dynamics, visualizer, reverb and spatial effects. Original local songs are not uploaded to a developer-operated server merely to play or process them.
04Private cloud and server connections
Connected sources are optional and initiated by the user. UNIFY Music may process the minimum information required to browse the chosen location, build a local music index, show metadata and artwork, stream audio, seek and cache completed or partial audio.
Dropbox
- OAuth account authorization and a selected folder or path.
- Folder structure, file IDs or paths, names, types, sizes, modification data, audio content, tags and artwork required for the music library.
- Saved source index and offline status information on the Android device.
- Disconnect and remove-library actions that do not delete the original Dropbox files.
WebDAV
- Server URL, selected folder, connection label, username and password or app password where required.
- Multiple saved WebDAV connections and folder selections.
- Folder scanning, metadata, artwork, playback and later synchronization of changes.
- HTTPS is recommended. An unencrypted HTTP server may expose traffic to network observers.
SMB2 / SMB3 and NAS
- Server address, share name, selected folder and optional username, password, domain or workgroup.
- Multiple saved SMB/NAS connections, connection testing and library synchronization.
- File information, audio content, metadata and artwork needed to browse and play the user's private share.
- SMB connections generally operate on the user's local or private network and depend on that network's security.
Credentials are private connection data. They are not displayed in Community posts or shared with other Community users. Users should protect their device, accounts, server passwords and network.
05Google Drive access and Google API data
When the user connects Google Drive, UNIFY Music requests the read-only Drive scope needed to browse an existing personal music library. The app may access:
- File and folder names, IDs, hierarchy and selected folder.
- MIME type, size, modification timestamp and other technical metadata.
- Audio file content required for metadata extraction, artwork display, playback, buffering, seeking and local cache.
- Basic Google account information required by the authorization flow.
UNIFY Music uses Google Drive information only for user-requested music-library functions. It does not use Drive access to create, edit, rename, move, upload, share or delete Google Drive files.
The narrower drive.file scope is insufficient because users need to browse existing nested music folders and audio files that were not created by UNIFY Music.
Google API Limited Use: UNIFY Music's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Users can disconnect Google Drive inside the app and can revoke UNIFY Music access from their Google Account security settings.
06Progressive playback, source indexes and offline cache
To reduce waiting and support remote playback, UNIFY Music may:
- Build an on-device index of supported songs, folders, metadata and artwork.
- Download an adaptive initial buffer before playback begins.
- Continue downloading the current song sequentially while playback reads completed bytes.
- Request a new range or recover from the saved position when the user seeks or playback is interrupted.
- Retain fully downloaded songs for offline playback according to the user's cache settings.
Cache controls may include off, a storage limit, Wi-Fi only, Wi-Fi and mobile data, keep-after-disconnect and clear-cache options. Android may also remove cache automatically when device storage is low.
Disconnecting a source
- Disconnecting stops future authorized access to that source.
- The saved library index may remain on the device so the user can see previously indexed songs and offline status.
- Cached audio may remain when the user chooses to keep it.
- Removing a saved library deletes local song entries, metadata and artwork for that source, not the original provider or server files.
- Clearing cache removes downloaded copies from the Android device, not the original cloud or NAS music.
Original-source protection: removing a source library, clearing cache or disconnecting does not delete songs from Google Drive, Dropbox, WebDAV or SMB/NAS.
08How information is used
- Playback and audio processing: local and remote music playback, seeking, EQ, visualizer, effects, timers and editor tools.
- Connected-source operation: authorization, folder browsing, indexing, synchronization, metadata, artwork, progressive playback and offline cache.
- Authentication: sign eligible users aged 16+ into optional Community services.
- Community: display profiles, publish and distribute presets or posts, record interaction and deliver relevant activity notifications.
- Moderation and safety: investigate reports, enforce age restrictions, remove prohibited content and prevent abuse or fraud.
- Purchases: confirm Google Play trials, subscriptions and one-time entitlements.
- Diagnostics and product improvement: investigate crashes, compatibility, network errors and aggregate feature performance.
- Legal compliance: respond to valid legal requests and protect users, the developer and the service.
UNIFY Music does not sell private music files, connected-source credentials, OAuth tokens, email addresses or Community account data to advertisers or data brokers.
09Service providers, public content and disclosures
Information may be processed by providers that support UNIFY Music, including:
- Google APIs and Google Identity: Google Drive authorization and read-only music access selected by the user.
- Dropbox APIs: Dropbox authorization and selected music-source access.
- Google Firebase or equivalent infrastructure: optional Community authentication, database, notifications, moderation and server functions.
- Google Play: app distribution, billing, subscription management and entitlement validation.
- Analytics, crash-reporting or advertising providers: only where enabled and subject to applicable platform and consent controls.
- Email-delivery providers: necessary account messages and, only after separate opt-in, optional product email.
WebDAV and SMB/NAS traffic is sent to the server chosen by the user. The server owner and hosting provider may process connection logs and files under their own terms.
Published Community profiles, posts, presets, comments and share cards are intentionally public within the eligible Community. Information may also be disclosed when required by law, to protect users or the service, or as part of a legitimate business transfer.
10Advertising, analytics, communications and billing
Advertising
The free version may display ads where enabled. Advertising partners may process device, advertising or approximate technical identifiers according to applicable consent choices and their own privacy policies. Private music files and storage credentials are not supplied to advertisers.
Analytics and diagnostics
UNIFY Music may process app version, device category, playback or feature events, network errors and crash traces to improve stability, compatibility and security. Diagnostics are not intended to include original music files or private server passwords.
Email and notifications
Necessary account, security, deletion, purchase, moderation and policy messages may be sent to eligible account holders. Optional marketing email is off by default and requires a separate affirmative opt-in available only to users aged 16 or older. Every marketing message must include an unsubscribe method.
Billing
Google Play processes purchases. The developer may receive product ID, purchase token, transaction state and entitlement information, but not complete payment-card or bank details.
11Security, storage and retention
- OAuth tokens, server details and credentials may be stored on the Android device using available platform protections so the user can reconnect.
- Provider-supported encrypted transport is used where available. HTTPS is recommended for WebDAV.
- SMB/NAS security depends on the user's local network, server configuration, password strength and protocol support.
- Source indexes and cache remain until removed by the user, Android storage management or app deletion.
- Community account data is retained while active and until a valid deletion request is processed.
- Billing, security, fraud-prevention, moderation and diagnostic records may be retained where reasonably necessary or legally required.
- Anonymous or aggregate statistics may be retained after they no longer identify a user.
No security method is completely risk-free. Users should protect their Android device, provider accounts, NAS, passwords, network and backups.

13Children, teenagers and Community eligibility
Under 13
UNIFY Music is not intended for children under 13. If we learn that personal information from a child under 13 was collected, we will investigate and delete it where required.
Ages 13–15
Users aged 13–15 may use the core player, equalizer and private cloud/server playback where their provider account and local law allow it. They cannot enter Community, hold a Community account, publish or download Community presets, create a Community profile, comment, follow, like, favorite, repost or use other Community interactions.
Age 16 and older
Community is available only after the user confirms they are at least 16 and completes supported account requirements.
Underage Community accounts
If we reasonably believe a Community user is under 16, Community access may be restricted immediately while the account is reviewed. Confirmed underage Community data may be deleted or anonymized.
No parental-consent bypass: users under 16 are not permitted to participate in Community even if a parent or guardian gives permission.
14Changes and contact
This policy may be updated when app features, providers or legal requirements change. Material changes will be announced through the app, website, Play Store listing or account communication where appropriate.
If a future use of data requires fresh consent, UNIFY Music will request that consent separately rather than silently expanding an earlier consent.
