1. What the app does
Boreal Music (com.luminetz.borealmusic) is a player for audio files stored on your device. It lets you choose folders, organize playlists, view local lyrics, sync lyrics yourself and customize playback and appearance. It needs no account and no music server, does not stream music over the internet and shows no ads.
2. Data the app accesses
With your permission, the app reads audio files and their metadata: title, artist, album, duration and artwork. In folders you choose, it can also read related artwork and lyrics files. It stores file paths or identifiers, a local index and SHA-256 fingerprints used to recognize identical copies. Fingerprints are never sent to any service.
3. Data stored on your device
The app keeps playlists, favorites, preferences (including appearance: light, dark or system theme, accent color and high contrast), scan rules, authorized folders, playback position and queue, the profile name and photo you choose, local title/artwork edits and listening statistics. These statistics include songs played, dates and listening time. They stay on the device and are not synced between devices.
The app also stores, only on the device:
- Listening history and summaries: the monthly and yearly summaries (top songs, artists and albums, most active day and hour, streaks and comparisons) are computed on the device from that history. Nothing is sent anywhere.
- Synced lyrics: if you use the lyrics sync tool, the lyrics you time are saved as .lrc files in the app's private storage. They are exported only if you choose to.
- Playback resume positions: the position of long audio files, the playback speed and the audio settings you choose.
- Widget data: the title, artist and artwork reference of the last song, so the home-screen widget can show it.
- Live wallpaper settings: intensity, reactivity and colors of the Aurora wallpaper. The app also stores whether Boreal Music Pro is active, so it can open offline with the unlocked features.
4. How data is used and transferred
This data is used to play, search and organize your library, show your statistics and remember your settings. The app has no servers of its own, no remote accounts, no ads, no remote analytics, no tracking and no online lyrics search. The developer does not receive your music, library, lyrics, photos or statistics, and does not sell data.
The app's only outside communication is through the Google Play Billing library described in section 5. Because of it, the Google Play install shows network access permissions; playback, the library and statistics work the same offline.
5. Boreal Music Pro purchase (Google Play)
Boreal Music Pro is an optional one-time purchase, with no subscription, that unlocks additional effects, styles, accent colors, the live wallpaper, the lyrics sync tool, the full listening summary, share cards, practice tools and controls. The purchase is handled entirely through Google Play Billing:
- Google processes the payment. Neither the app nor the developer receives or stores your card number, payment details, or your Google account name or email.
- To activate Pro, the app asks Google Play for the status of your purchases and receives the status of the Boreal Music Pro purchase (purchased, pending or not purchased), the product identifier (boreal_music_pro) and a purchase token. The app uses the token only to acknowledge the purchase with Google Play, as Google requires, and stores on the device only whether Pro is active.
- This information is not sent to any developer server. The app checks with Google Play again each time it opens, so refunds and restored purchases are reflected automatically. "Restore purchase" repeats that check.
- The Google Play Billing library included in the app communicates with Google Play and may send Google technical information about how purchase operations perform. Google processes that data and your purchase data as an independent controller, under the Google Privacy Policy (https://policies.google.com/privacy) and the Google Play terms.
- Receipts, order history and refunds are managed from your Google Play account.
6. Backup file
In Settings you can save a backup and restore it later. The backup is a single JSON file that you save in a location you choose with the Android file picker, which can be on the device, a USB drive or a cloud provider you have installed. It can contain your settings, playlists, favorites, listening history, saved equalizer curves, and your profile name and photo, plus the title, artist and file name of the songs they refer to. It does not contain your music files, your synced lyrics, your folder permissions or your Boreal Music Pro purchase.
The file is not encrypted: anyone who can open it can read it, so keep it somewhere you trust. The app never uploads or sends it anywhere; it only reads or writes the location you pick. When you restore, you choose which parts to apply, and the app only reads the file you select.
7. Home-screen widget and live wallpaper
The "Now playing" widget and the Aurora live wallpaper (Pro) read only the playback state of Boreal Music itself on your device: whether something is playing, the title, the artist, the cover and its dominant color, and the audio level of the song that is playing. They do not read other apps, your microphone or your files, and they do not send anything out of the device. The wallpaper never starts playback.
8. Sharing and system services
Only when you choose Share does the app prepare a copy of the audio file, or an image of the song, of your profile, of your listening summary or of a lyric card, and hand it to the app you select. Share cards are images created on the device and are shared only when you choose to; the temporary copy is kept in the app's cache. Shared content may include title, artist, artwork, lyric lines and statistics, depending on the feature. The receiving app applies its own privacy terms. Choosing a photo or folder may open system or third-party providers, including cloud providers you have installed.
When you set a ringtone, Android storage and settings are used with the corresponding permissions. The copy created as a ringtone may remain outside the app's private data.
9. Permissions
Audio or storage: discover and play authorized files; on older Android versions, export a ringtone when needed. Folders and photos: access through system pickers. Notifications: show playback controls. Foreground service and wake lock: keep playing with the screen off. Modify system settings: only when you ask to set a ringtone; Android takes you to its settings to grant it. Google Play billing and network access: buy and verify Boreal Music Pro through Google Play. The visualizer, the widget and the live wallpaper use only the audio and state of Boreal Music's own playback; the app never records the microphone. The widget and the live wallpaper are declared system components and need no extra permission from you; the live wallpaper is optional and only active if you choose it in Android.
You can deny or revoke permissions in Android Settings. Some features will then lose access to files. The app lets you request access again or use selected folders instead.
10. Retention and deletion
Indexes, statistics, summaries, synced lyrics, resume positions, widget and wallpaper settings, preferences, artwork and playlists are kept in the app's private storage until you clear its data or uninstall it. Share copies (including share cards) and other caches can be removed with Clear cache in Android; the system may also free cache space. Removing a song from the library does not delete the original file.
To delete all of the app's local data, open Android Settings > Apps > Boreal Music > Storage > Clear data, or uninstall the app. This does not delete your original music files or copies you have shared, backup files you saved, lyrics you exported or ringtones you exported. The app does not enable automatic cloud backup of its private data.
Clearing data or uninstalling does not cancel your Boreal Music Pro purchase: it stays linked to your Google account and can be restored. Google keeps the purchase record under its own policies.
11. Security
Android keeps the app's private storage separate from other apps, according to your device's security. Access to shared files depends on the permissions you grant. There are no accounts, passwords or remote storage. Payments are protected by Google Play. Backup files are not encrypted, so store them carefully.
12. Children
The app has no advertising, no communication between users, no content from other users and no remote tracking. It is not specifically directed at children under 13. Google Play purchases are subject to the parental controls and purchase authentication offered by Google Play.
13. Changes and contact
If external services, advertising or new data transfers are added, this policy and the store declarations will be updated before those features are distributed. The date above shows the latest version.
