How does cashlog store portfolio data differently?

cashlog works with a local file on your disk (File System Access API, Ctrl/Cmd+S) plus navigator.storage.persist(), optional AES-256-GCM vault, and no automatic per-ISIN quote requests that would leak holdings with your IP.

Who should pick cashlog over Portfolio Performance or Parqet?

Investors who want real local disk storage without a Java install, bond math (accrued interest & YTM), ECB FX split, AT/DE/CH tax views, and a browser UI on Mac, Windows, Linux, iPad and iPhone.
