PRAXIS SCIENCE LAB / ANDROID
AudioLab — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-08. This notice describes Android version 0.3.1 (4) 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
Live microphone samples and user-selected audio files are processed on your device. AudioLab stores preferences, session names and state, file references and numeric measurement records in its private local database. Microphone analysis is started by the user and stops when the app leaves the foreground. The app has no account, analytics, advertising or cloud service. The Android release removes Internet and network-state permissions.
Permissions, services and sharing
RECORD_AUDIO is requested for live analysis. You can deny or revoke it in Android Settings and continue with features that do not need the microphone. Audio-file access is granted through the system picker. Exporting a chart, session or PDF writes the information you choose to a system-selected destination, which may be a cloud-backed document provider. Such a provider handles its copy under its own policy. The app does not automatically upload microphone audio.
Retention and deletion
Saved sessions can be deleted in the app. Clear Android app storage or uninstall to remove the private database, including stored measurements and settings. Android app backup is disabled. Original audio files and exported reports, charts or session files are separate from private storage and remain until you delete them from their destination. Removing a session does not delete an original source file.
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.
