No upload path
The application processes the configured signals locally and writes the result to a CSV file you choose. Your files remain under your own storage policy.
Your observation stays on your Mac.
Key Recorder has no network service, no account and no analytics inside the application. It is deliberately small enough to inspect.
Transparent permissions
Enable Input Monitoring in System Settings so the app can receive the configured keys during a recording. Accessibility is not required for passive recording. The app does not store what you type.
Know what is stored
Key Recorder measures durations, not interaction counts. Session titles, protocol notes and metadata you enter are saved in the local archive. It does not identify participants automatically.
