1. The Core Guarantee: Zero Server-Side Processing
EtsyFeeKit is engineered as a static, client-side web application. Every calculation, formula evaluation, chart rendering, and PDF/CSV export runs exclusively within your browser's local JavaScript engine. We do not operate an application database or backend API that receives or logs your financial figures, item prices, material costs, hourly rates, or sales margins.
2. Local Storage Usage
To provide a seamless user experience, EtsyFeeKit may save your latest calculator inputs and preferred color theme in your browser's native localStorage. This data never leaves your device and is never synchronized to the cloud. You can clear this stored state at any time by clearing your browser cache.
3. Analytics & Third-Party Trackers
EtsyFeeKit does not utilize invasive third-party ad networks, tracking pixels, or user fingerprinting scripts. Static hosting assets are delivered over the secure Cloudflare Global Edge Network, which captures standard, privacy-preserving HTTP transmission logs (e.g., requested file paths and status codes) strictly for DDoS prevention and infrastructure reliability.
