Privacy Policy

Last updated: March 29, 2026

The short version: Your files and data never leave your device. We don't collect, store, or transmit any of your spreadsheet data. Everything runs locally in your browser.

How the tool works

excel2cal.com is a 100% client-side web application. When you upload a file, it is read and processed entirely within your web browser using JavaScript. No data is sent to any server — not ours, not anyone else's.
