Why does Windows show a SmartScreen warning?

These applications are distributed directly by the author and are not digitally signed with a commercial code-signing certificate.

Because of this, Microsoft SmartScreen may display a warning such as:

"Windows protected your PC"

This does NOT mean the application contains malware.
It only means that Microsoft does not have enough reputation data for this executable.

The software is a self-contained Electron application that runs locally on your computer and does not require an account, telemetry, advertising, or online services.

Run anyway

Some versions of Microsoft Edge may block the download completely and may not offer a "Run anyway" option.

If this happens, try downloading the file with a different browser. Several users have reported successful downloads using Thorium Browser:

These applications are distributed directly by the author,

subscriptions or cloud services.
