Data Collection

Maker Margin Planner does not collect, sell, rent, or transmit pricing inputs, CSV rows, calculation results, browsing history, or personal information.

Network Activity

The calculator has no backend service and no analytics SDK. The extension source does not call fetch, XMLHttpRequest, sendBeacon, or third-party analytics services.

Local Processing

Inputs entered into the popup and CSV rows pasted into the batch planner are processed locally using JavaScript.

Browser Storage

Maker Margin Planner uses browser extension storage only for the offline license code used to activate the extension.

License codes are verified locally. They do not cause calculator inputs, CSV rows, results, or browsing history to be sent anywhere.

Permissions

The extension uses the storage permission only for license-code storage. It does not request host permissions or run content scripts on marketplace pages.
