PRAXIS SCIENCE LAB / ANDROID
Spectrum Lab — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-16. 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
Microphone samples are analysed on the device. The app stores session names, notes, settings and numerical measurements in private local storage, not raw audio recordings. There is no app account or developer-operated audio upload service.
Permissions, services and sharing
Microphone permission enables sound analysis. A microphone foreground service and notifications support explicitly started screen-off monitoring and local alerts. The Lab edition does not request ads or offer purchases.
The separate Standard development edition integrates Google test advertising, consent and Play Billing. Google services may process connection and device information under their own policies: https://policies.google.com/privacy . Local audio processing does not mean that the advertising edition has no network traffic. Commercial subscription verification is not configured.
Retention and deletion
Deleting a session removes its local measurements. Clearing app storage or uninstalling removes private sessions and preferences. Files exported to another location remain there until you delete them. Export important measurements before uninstalling.
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.
