gotcha

Catches people trying to use your computer while you're away. Grabs all input devices so nothing works, snaps a timestamped webcam photo when someone tries, and unlocks with a secret key.

Working on macOS and Linux.

Setup

macOS

The app needs Accessibility API access to grab input devices.

1. Open System Preferences > Security & Privacy > Privacy > Accessibility
2. Add your terminal app (e.g. Terminal.app, iTerm2, Alacritty) to the list
3. Run with cargo run

Linux

The app needs access to /dev/input/* devices to grab keyboards and mice.

1. Add your user to the input group:

   sudo usermod -aG input $USER
   

2. Log out and back in for the group change to take effect
3. Verify with groups — you should see input in the list
4. Run with cargo run

Usage

1. Run cargo run
2. All keyboard and mouse input will be grabbed — the desktop becomes unresponsive
3. Any input triggers a timestamped webcam photo saved to captures/
4. Press Escape to release all devices and exit
