The file isn’t code-signed yet, so Windows SmartScreen is cautious with new files: click More info → Run anyway. What you downloaded is exactly the file we published.
2 · The trial starts on first launch
3 days with everything unlocked — no signup, no card, nothing to configure. When it ends, the app locks until you enter a key.
3 · Like it? Unlock it
Get a license on the pricing page — $8.99 one-time, key by email in seconds, and the app you already installed unlocks with it. Portable, 100% local, zero telemetry.
