How the trial works

  1. Download and install — no sign-up, no key.
  2. On first run, a short setup downloads the local detection model. The 14-day trial starts automatically.
  3. The trial is anchored to your device, so reinstalling won’t reset it.
  4. When you’re ready, buy a license and activate it in-app — one-time, perpetual, node-locked to your device.
