5.2 Content Delivery Networks
We use CDNs (Content Delivery Networks) to serve static resources such as CSS frameworks, fonts, and JavaScript libraries. These services may collect technical information about your visit for performance and security purposes.

Since your financial data never leaves your browser:

However, you should:

Since we don't store your financial inputs:
- Your calculation data exists only during your browser session
