01
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.
LOCAL BY DESIGN
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.
02
Transparent permissions
macOS requires Accessibility and Input Monitoring permissions so the app can receive the selected keys outside its own window. It does not read general keyboard input.
03
Know what it does not record
Key Recorder does not identify participants, store experiment metadata, count interactions automatically or replace your lab notebook.
