This Privacy Policy documents the privacy protocols of Prism Calc: Reactive Canvas ("the Application"), developed, published, and maintained by Soft Trump Software Solutions. The Application is engineered under a strict "Privacy-by-Design" framework as a standalone mathematical utility. We do not collect, process, track, or transmit your calculation history, formulas, variable links, or device-specific metrics to any remote infrastructure, cloud servers, or third-party networks.
Local Ledger Persistence: Every mathematical expression, card entry, calculation sheet, and relational formula link you create exists strictly within your device's local sandboxed filesystem. This data is held in temporary memory (RAM) for real-time reactive calculations and committed directly to local persistent storage paths.
Zero Cloud Synchronization: The Application operates entirely without user accounts, cloud backups, or mandatory registrations. We do not capture or hold Personally Identifiable Information (PII) such as your name, email address, or device identifiers.
Privacy Isolation: Your calculation sheets and ledger history are completely confidential. Because the Application operates 100% offline, we have zero technical visibility into the math or data you input into the canvas.
To deliver an immersive, highly responsive interface, Prism Calc interacts only with minimal, non-sensitive hardware layers:
Haptic Actuators: Executes localized physical vibrations to provide real-time tactile feedback when using the custom keypad.
Local Storage Storage Read/Write Paths: Standard sandboxed operating system permissions required exclusively to reload your calculation ledgers across app lifecycles.
System UI Engines: Interacts with native layout modules to configure an edge-to-edge workspace that seamlessly scales around camera notches and system navigation bars.
The Application code architecture intentionally excludes third-party advertising software development kits (SDKs), analytical tracking pixels, and user profiling frameworks. Global application downloads and baseline platform stability metrics are processed exclusively through the standard, automated infrastructure of the Google Play Console ecosystem.
You retain absolute ownership of your data. You can clear individual cards, clear entire calculation sheets, or wipe your full history inside the user interface. Uninstalling the Application from your device or using the Android System Settings to clear app storage will immediately and permanently erase all locally stored data. We do not maintain remote mirrors or external backups.
