StacKova publishes NABRA, a player for audio files available on your Android device. For privacy questions or information you voluntarily send to support, contact [stackova8@gmail.com](mailto:stackova8@gmail.com).
Local playback and free access
All features in this release are available at no charge. NABRA does not require an account or sign-in, display advertising, or offer in-app purchases or subscriptions. The FREE release does not use a purchase-verification service, advertising tracking or listening-behavior analytics.
Files and data on your device
When you allow audio access, NABRA reads files and available information such as titles, artists, albums, durations, artwork and storage references to display your library and play your selections. Library, search and listening information are processed locally. NABRA does not automatically upload your audio files or library to a server.
The app keeps local library indexes, the queue and playback position, playlists, favorites, bookmarks, smart-list rules, imported lyrics, settings and personal sound presets. It does not create a public profile or a cloud listening history. You can refuse or revoke audio access in Android settings; features that need access to those files will then be unavailable.
A media playback service lets audio you chose continue when you leave NABRA's screen, with Android playback controls. The system may display the track title or artwork in media notifications, on the lock screen or in a widget you add. Android settings control the visibility of this information. Audio-file access is not microphone permission: NABRA does not record your microphone.
Imports and exports you choose
Backup and restore use Android's document picker. NABRA asks the picker for local files and save locations on the device. You choose the local file and where to save or import it. A backup contains supported app data such as playlists, favorites, bookmarks, smart-list definitions, settings and track references. It does not contain the original audio recordings or the active queue.
Importing lyrics or backup data is an action you choose, and NABRA requests local files for these operations. Backups exported from NABRA are saved locally. The app does not provide cloud upload or synchronization and does not send the backup to StacKova. You can later move or upload a file using your files app or another app you choose. That action takes place outside NABRA and is subject to the app or service's policy. Displaying local files depends on Android and the document provider; NABRA does not prevent copying or transfers performed by you or the system outside the app.
External links and support
The privacy link and license-source links open a browser, and the support link opens an email app on your device. The browser, website or email app may process information under its own policies. Opening these apps does not automatically attach your library, audio files or listening records.
If you choose to email support, StacKova receives your email address, message and any attachments you decide to send, and uses them to answer and follow up on your request. The email service stores messages under its settings and policies. You do not need to contact support to use NABRA's local features.
Retention and deletion
Local NABRA data remains until you remove it through an available app control, clear app storage or uninstall the app. Original audio and files exported outside NABRA's storage are not automatically deleted when you uninstall it. Manage those files in your files app, and manage any copies you later transfer through the service you chose.
We retain support correspondence for as long as needed to handle and follow up on the request, or to meet an applicable legal obligation. You can ask about or request deletion of information you voluntarily sent by contacting support. If a legitimate reason requires retaining part of it, we will explain that reason. There is no separate NABRA account that needs an account-deletion procedure.
Protection and changes
NABRA relies on Android's app-storage protections and access permissions and disables automatic Android app-data backup. NABRA does not transfer user data over a network or provide a server for storing it. Choose an appropriate location for local exports: uninstalling the app does not delete them or retrieve copies you later transferred to another app or service.
