PRAXIS SCIENCE LAB / ANDROID
Mosaic — Privacy Policy
How Praxis Science Lab handles information for this Android app.
Effective date: 2026-09-12. This notice describes Android version 0.5.0 (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
Selected photos, text, collage settings, project thumbnails and language preferences remain in private app storage. Mosaic does not upload photos or collages to a developer-operated server. There is no app account or cloud backup.
Export writes an image to Pictures/Mosaic through MediaStore. Sharing sends the chosen export to the application selected by the user, which has its own practices.
Permissions, services and sharing
Mosaic accesses selected photos through the Android document picker and exports images to the gallery. It does not request camera, microphone, contacts or precise location.
Google Mobile Ads Next-Gen 1.4.0 and Google UMP 4.0.0 are included. Commercial identifiers are unset and that flow is disabled in the signed 0.5.0 release. In the debug build, opening Test advertisement can contact Google. Demo ads generate no revenue but may process connection information, identifiers, interactions and diagnostics. Google policy: https://policies.google.com/privacy
Future commercial advertising will obtain applicable privacy choices through UMP before requests. Advertising privacy options appear in Settings when required. A banner is limited to export completion, without blocking editing or saving.
Retention and deletion
Delete named copies through Projects. Free unused storage removes app-owned photo copies only when no project, draft, recovery file or current undo/redo history references them. Unreadable metadata stops cleanup. Clearing storage or uninstalling removes private projects and settings; Android backup is disabled. Gallery exports remain until deleted separately. Google controls retention of data processed by its advertising services.
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.
