Praxis Graph — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-15. 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
Calculations, expressions, history and Pro workspace data are processed and saved on the device. No developer-operated account or calculation server is required.
Permissions, services and sharing
Google Play Billing is integrated for a planned one-time purchase. Google handles the payment flow; the app verifies and caches purchase information for access restoration. The developer does not receive payment-card details. Production purchase configuration is not active in version 0.1.0. No advertising SDK, UMP integration or advertising identifiers are included. Calculations do not require media, microphone or location permission.
Retention and deletion
Clearing app storage or uninstalling removes private calculation data and settings. Google controls retention of purchase records. A verified purchase can be restored through Google Play once commercial purchasing is configured.
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.
