Security and privacy

Does Hurricane need an internet connection?

No. Hurricane is fully functional offline. The only thing that ever touches the network is the Check for Update item in its menu, which runs only when you click it.

That check requests a small version text file from 74mph.com. It sends nothing about you, your PC or your drawings.

Do drawings or their data leave the PC?

No. Hurricane builds AutoCAD script files on your PC and runs them in your own CAD program, on the drawings you choose. No drawing, no drawing content and no metadata leaves the workstation. Hurricane changes drawings only through the scripts you build and run.

Licensing and activation

There is no activation server and no online license check. The license is a key file that sits on the PC, a network share or a USB stick, and it keeps working with no connection.

Background services and start-up

None. The installer registers no Windows service, no scheduled task and nothing that starts on its own. Hurricane runs only when you launch it. It installs no browser add-ins and loads nothing into other applications: it is a stand-alone program, not an AutoCAD plug-in.

Telemetry

None. There is no telemetry, analytics or usage collection of any kind.

What Hurricane writes, and where

• Files: only in its own install folder, in its DATA and SCRIPTS subfolders (such as its file lists and the scripts it builds).
• Settings: a few values, such as its install path, under HKEY_CURRENT_USER\Software\VB and VBA Program Settings\HurricanePowerTool.
• Your drawings: only through the scripts you run, in your own CAD program.

Verifying the installer

Hurricane is not code-signed, so Windows or your browser may show a caution prompt on a fresh download. Every release lists its SHA-256 checksum on the download page, with a checksum file and a step-by-step verify page, so you can confirm your copy is exactly the file published here before you run it.
