Local Settings & Preferences: The extension saves your input such as electricity rate, default voltage, usage hours, generator efficiency, and appliances you add to the load planner.

The extension requests minimal permissions to work properly:
activeTab: To analyze content on the active tab when you activate the extension.
storage: To save your preferences (electricity rates, appliance list, etc.) locally.
scripting: To display cost tooltips by injecting lightweight scripts on pages.
contextMenus: To allow quick conversions when you right-click selected text.
tabs: To connect popup calculations with the correct browser tab.
host permissions: To detect power values (W, kW, HP) on shopping/product sites.
These permissions are used only to provide the extension’s single purpose and nothing else.
