Before you download

Is Stratum a native app or an Electron/web app?

Native. The Mac version is built in Swift and the Windows version is a native Windows build — not Electron, not a browser wrapper. That's why it starts instantly, scrolls through millions of rows, and works fully offline.

Is my data private?

Yes. Your data stays on your computer — Stratum never uploads your files, datasets, or results to a server or the cloud. The app checks your license periodically and looks for updates; neither request carries any of your data.

What are the system requirements?

macOS 14 (Sonoma) or later, or Windows 10 or 11 (64-bit). There are no other dependencies to install.
