2. Local-First Architecture (Zero Cloud Storage of Calculations)
Unlike cloud-connected accounting or subscription math tools, Calculator is engineered as a 100% on-device application:
- Local Calculation Engines: Standard math arithmetic, scientific trigonometry, logarithms, unit conversions, loan EMI amortizations, GST/VAT tax figures, BMI scores, and number base conversions are computed entirely by the device CPU.
- Zero Remote File or Data Uploads: Your calculation formulas, numeric values, custom unit inputs, and history logs are never sent to Gree Web Solutions servers or third-party cloud infrastructure.
- Offline Functionality: All calculation and conversion features operate completely offline without internet connectivity.
3. Android Device Permissions & Technical Purposes
Calculator requests minimal permissions strictly necessary to deliver ad-supported functionality:
