We respect your privacy and are committed to providing a secure, transparent, and privacy-friendly experience.
Watt Wise is an offline Android application designed to help users estimate electricity consumption, calculate electricity costs, manage appliance usage, and explore preliminary solar panel, inverter, UPS, and battery backup requirements.
This Privacy Policy explains how the application processes information and handles locally stored data.

Payment or banking information
All electricity consumption estimates and calculations are performed locally on the user's device.
Watt Wise is designed to work entirely offline.
Users can access its core features without creating an account or connecting to an online service.
The application provides:
Electricity consumption estimation
Estimated monthly electricity bill calculations
A built-in appliance catalog
Custom appliance management
Solar panel capacity estimates
UPS and inverter sizing estimates
Battery backup capacity estimates
The application does not connect to electricity providers or automatically access electricity meters.
Watt Wise uses Android SharedPreferences to store application settings and user-created appliance information locally on the device.
Stored information may include:
Appliance names
Appliance wattage and quantity
Daily usage hours
Load percentages
Backup appliance selections
Electricity rates and additional charges
Currency and billing period settings
Theme preferences
This information is used exclusively to support application functionality.
DG Apps Labs does not maintain an online database of users' appliance lists, calculations, or preferences.
Depending on Android device settings and the application's backup configuration, locally stored data may be included in Android's system backup and restoration process.
Watt Wise estimates electricity consumption and costs using user-provided appliance information.
Calculations are performed locally.
The application does not access:
Electricity provider accounts
Smart electricity meters
Official billing records
Banking or payment information
Estimated bills may differ from actual electricity bills because of tariff structures, taxes, fixed charges, and variations in appliance usage.
Watt Wise provides preliminary estimates for solar panels, inverters, UPS systems, and battery backup requirements.
These estimates use user-provided values and simplified calculations.
The application does not remotely connect to solar equipment, batteries, inverters, or monitoring systems.
Results are intended for general planning and educational purposes only.
Users should consult a qualified electrical or solar installation professional before purchasing or installing electrical equipment.
Watt Wise does not require special or sensitive Android permissions for its described core features.
The application does not require access to the device's camera, microphone, location, contacts, photos, or external storage.
An internet connection is not required to perform calculations or manage appliances.
The described version of Watt Wise does not intentionally integrate advertising networks, analytics tracking services, or third-party user profiling services.
The application uses Android and Jetpack Compose components to provide its interface and functionality.
If third-party services are added in future updates, this Privacy Policy will be revised to accurately describe any related data handling practices.
Watt Wise is designed to minimize privacy risks by processing calculations locally and avoiding unnecessary personal information collection.
Application preferences and appliance records are stored within Android's application storage.
DG Apps Labs does not operate remote servers to collect or store users' electricity estimates or appliance records.
Locally stored appliance information and settings remain available until users modify or remove them, clear application data, or uninstall the application.
Users can:
Add, edit, and delete appliances
Clear their saved appliance list
Modify calculation settings
Change theme preferences
Clear application data through Android settings
Uninstall the application
Uninstalling generally removes locally stored application data, subject to Android backup and restoration settings.
Because Watt Wise does not maintain user accounts or developer-operated personal information databases, no separate server-side account deletion process is required.
Watt Wise is a general-purpose utility application.
The application does not knowingly collect personal information from children or adults through its described features.
No account registration or personal information is required to use the application.
Watt Wise provides estimates based on user inputs, typical appliance wattages, and simplified mathematical formulas.
Actual electricity consumption, utility bills, solar generation, and battery performance may vary.
The application is not a certified electricity measurement device or a substitute for professional electrical engineering advice.
Users should verify important calculations with their electricity provider or a qualified professional.
DG Apps Labs may update this Privacy Policy to reflect changes in application functionality, data handling practices, or applicable requirements.
Updates will be published with a revised effective date.
