INSTALLATION

Choose the Windows installer package.

System requirement: 64-bit Windows 10 or later.

  1. Open the latest GitHub Release and download the Windows x64 EXE installer.
  2. Run the installer and review any Windows SmartScreen message before continuing.
  3. Launch Lumi and grant camera access only if you want context-aware monitoring.
  4. Use the tray icon to configure Lumi, reminder switches, and the monitoring schedule.
Preview-build notice: The Windows installer is not currently code-signed and may trigger SmartScreen. Verify that the publisher URL is the official Lumi GitHub repository before running it.

What stays on your computer

Camera frames are processed in memory with MediaPipe and discarded. The app stores a 30-day local timeline of small behavior events in IndexedDB. It does not upload photos or video, capture your screen, or require an account.

Reminders you can enable

  • A prolonged gap between detected complete blinks.
  • A 20-second distance break after 20 minutes of observed screen time.
  • A configurable sedentary interval between 1 and 600 minutes.
Not a medical device

Lumi supports screen habits. It does not diagnose digital eye strain or dry eye disease and does not replace professional eye care.
