PRAXIS SCIENCE LAB / ANDROID
Praxis Clean — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-19. This notice describes Android version 0.16.3 (20) 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
File review processes names, paths, sizes, modification times, content fingerprints, thumbnails and compression locally. The local journal stores operation states, file references and fingerprints for verification and restoration. Photo selections, language and other preferences stay on the device. Installed-app inventory supports file ownership and app management; optional usage access supports exclusions. No developer-operated account is required.
Permissions, services and sharing
Storage access is requested according to the selected tool. Usage access, Shizuku, root and Accessibility are optional and can be refused or revoked. The app does not root the device. After individual confirmation, cache assistance inspects a recognized Android Settings screen for up to 45 seconds and performs at most one supported Clear cache action; it does not retain screen text or use it for advertising.
The evaluation build includes Google Mobile Ads and UMP with test identifiers. An optional test in Settings checks applicable consent before requesting ads. Google services may process IP addresses, approximate location, identifiers, interactions and diagnostics. Test advertising can still transmit data. Google privacy: https://policies.google.com/privacy . The app does not intentionally supply file contents, paths, installed-app inventory, usage records or the operation journal to advertising services.
There is no Billing SDK or separate analytics SDK in this version. User-initiated exports use the chosen document provider, which may synchronize files under its own terms. Default journal exports omit paths and hashes; an optional detailed export includes them. Android automatic app backup is disabled.
Retention and deletion
History offers manual removal of old journal records while preserving recoverable or uncertain operation receipts. Local trash has no automatic expiry. Restore needed files before clearing app storage or uninstalling: losing the private journal can prevent restoration of trash payloads. Clearing app data removes preferences and private records but does not necessarily remove shared-storage trash payloads or exported files. Manage exports at their chosen destination. Google controls retention of advertising-service data.
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.
