PRAXIS SCIENCE LAB / ANDROID
Prism Player — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-12. This notice describes Android version 0.1.0 (1) and the configuration documented below.
Praxis Science Lab is the publishing brand used by Traian Anghel. For support or privacy questions, email traiananghel@gmail.com. Include the app name and version. Do not send passwords, medical records, private recordings or other sensitive information.
Information handled by the app
The app reads audio files selected through the Android document picker or made available by an optional music-library permission. Track locations and metadata, playlists, favorites, play counts, language and appearance preferences are stored locally. Embedded album artwork is read locally. Audio files and library records are not uploaded by Prism. There is no account, microphone recording or cloud music library.
Permissions, services and sharing
Optional audio-library access is used for scanning: READ_MEDIA_AUDIO on Android 13 and later, or READ_EXTERNAL_STORAGE on earlier supported versions. The document picker can grant access to selected files without a library-wide permission. Media playback uses a foreground service, audio focus and a wake lock to support background listening and system controls. No microphone, location or all-files-management permission is requested. Internet and network-state permissions and Google Mobile Ads/UMP libraries are included for planned advertising, which is disabled in this build.
Retention and deletion
Remove library entries and playlists in the app to remove those local records while keeping the source audio files. Clear Android app storage or uninstall Prism to remove its library records, preferences and cached artwork; audio files stored elsewhere on the device remain. Library data is excluded from Android backup and device transfer.
Security
Private app files use Android application storage protections. No additional database-encryption guarantee is made. Keep your device protected and control access to files you export. There is no Praxis Science Lab account to delete for this app.
Support messages and external pages
If you contact us, we receive your email address and the information you choose to send. We use it to answer your request and resolve the issue, not for advertising. Correspondence remains only as needed for that purpose and any applicable legal obligations; you can request deletion. Our email provider processes messages under its own terms. We do not sell support correspondence.
Opening this policy or other external links sends ordinary connection information to the website or browser provider. See our website privacy notice. App-local data is not automatically included in those requests.
Your choices
You can clear local data and use the contact above to ask about support correspondence or request access, correction or deletion where applicable. We may need information to identify the relevant request. You may also contact your local data protection authority. Local app information is processed to provide the functions you use; support correspondence is processed to respond to your request.
Changes
We update this notice when app behavior or relevant practices change. The date and version above identify the policy you are reading.
