PRAXIS SCIENCE LAB / ANDROID
Scientific Calculator — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-08. This notice describes Android version 1.1.3 (5) 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
Calculation history (up to 50 results), number formatting, angle and base preferences, and language are stored in app-private storage. Calculations run on the device. The app does not transmit these records to Praxis Science Lab. No accounts, advertising, analytics or crash-reporting service are implemented.
Permissions, services and sharing
No camera, microphone, contacts or location permission is requested. The Android package declares Internet access through its framework, but the calculator has no application network requests and over-the-air updates are disabled. Opening the privacy or publisher link uses your browser.
Retention and deletion
Clear calculation history in the app to remove saved results. Clear the app's storage in Android Settings or uninstall to remove its remaining local settings and records. Android cloud backup is disabled for this app. Praxis Science Lab has no server copy to restore.
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.
