1. Client-Side Financial Privacy
HarkleTools operates on a privacy-first architecture. All calculation inputs—including item prices, shipping figures, production costs, and profit metrics—are processed strictly inside your web browser using client-side JavaScript.
Your financial data, sales volumes, product margins, and business numbers are never sent to, stored on, or transmitted across our servers.
2. Local Storage Usage
We use your browser's local storage solely to remember your visual interface preferences (such as your Light, Dark, or System theme selection). This information remains entirely on your device.
3. Third-Party Links
HarkleTools contains references and links to external websites, including official Etsy help documentation and policies. We are not responsible for the privacy practices or content of third-party websites.
