Privacy Policy for SCI-CAL Calculator

Application Identifier: com.tahir.scical • Effective Date: July 12, 2026

1. Algorithmic Isolation & Local Arithmetic Runtime

SCI-CAL (com.tahir.scical) is engineered under a zero-telemetry architectural paradigm. We firmly maintain that your mathematical formulas, currency conversions, engineering inputs, financial assets data, and productivity metrics belong entirely to you. The application operates 100% locally. Complex computations—ranging from basic algebra to advanced scientific calculus formulas—are processed strictly inside the sandboxed CPU registers of your physical mobile handset.

Offline Execution Assurance: SCI-CAL does not possess remote client-server hooks to capture or analyze input expressions. No algorithms, parameters, or calculated sums are ever transmitted to Neuron TS Labs or external storage clusters.

2. Internal Data Subsystems & Boundary Rules

To deliver modern productivity tools like calculation history caches and immediate text transfers, the app runs specific local memory utilities. Below is the technical disclosure of these pipelines:

Subsystem Engine Operational Mechanism Data Security Constraint
Room DB Isolated Log Maintains a historical record of your typed expressions and solutions inside an encrypted SQLite database stored locally on device disk space. This database is sandboxed natively. It has no external cloud syncing functionality, features automated size capping filters, and cannot be accessed by other installed apps.
Clipboard & Share Engine Allows users to copy output results into Android system buffers or utilize native system intents to export complete financial breakdowns to messaging channels. Data handles are ephemeral. The app reads system clipboards strictly when you choose the paste command, and outbound share sheets pass control entirely to native OS protocols.

3. UI Core Layer & Typography Mechanics

SCI-CAL features an advanced, adaptive layout engine constructed with Jetpack Compose. To protect visual display integrity across highly varied accessibility systems, the app includes an autonomous typography controller that automatically dynamically scales output values between 60sp and 100sp. This formatting occurs strictly inside memory layers and uses zero analytics instrumentation to map layout dimensions or user accessibility choices.

4. Advertising Networks & Pro Licensing State

To sustain independent utility development, the free tier of SCI-CAL incorporates standard mobile ad platform integrations (such as Google AdMob). These networks operate under independent container definitions:

  • Metric Collection Boundaries: Advertising SDKs may monitor coarse regional IP locations, device identifiers, and basic ad-click telemetry to handle frequency limits and prevent click fraud. They have absolutely no visibility into the Room database, local history stacks, or expression engines.
  • Premium Token Verification: If you purchase the permanent Pro Experience tier, transaction data passes entirely through the secure Google Play Billing API. SCI-CAL checks the validation token locally on-device to remove ads, change navigation labels, and open exclusive tools. No banking information is visible to the developer.

5. Autonomous Data Control & Erasure Protocols

Since your calculation records, financial variables, and conversion trackers are not synchronized with any central database, Neuron TS Labs cannot perform remote data removal actions. You have absolute sovereignty over your records.

To completely clear your calculation traces from the device, choose one of these instant methods:

  1. Use the manual "Clear History" button inside the calculation log layout to reset your Room DB tables immediately.
  2. Navigate to Android Settings → Apps → SCI-CAL → Storage → Clear Storage to return the app to a clean-slate state.
  3. Perform a standard uninstallation of the software package, which forces the Android OS to securely delete the entire sandboxed storage volume.

6. Governance Compliance & Communications

SCI-CAL is built as a generic utility and does not deliberately target or capture data from minors under the age of 13. By eliminating cloud pipelines, our architecture naturally satisfies global digital privacy laws, including the digital asset protection principles of the Republic of India.
