Loop Master — Custom Video Looper per Islam Kadeer

Loop Master lets you replay any part of a video automatically — perfect for practicing music, studying a tutorial step, learning dance moves, analyzing sports footage, or just replaying your favorite moment.

FEATURES
- Works on YouTube, Facebook, and virtually any site with an HTML5 video player
- Set a custom start and end point by typing a timestamp or grabbing the current playback position with one click
- Loop a set number of times, or loop infinitely
- Adjustable playback speed (0.25x–2x)
- Small draggable on-page panel with a visual progress bar showing your loop segment
- Keyboard shortcuts: Alt+I (set start), Alt+O (set end), Alt+L (toggle loop), Ctrl+Shift+L (show/hide panel)
- Loop settings are remembered per video, stored only on your own device
- On pages with multiple videos (like social feeds), the loop stays locked to the video you set it on — it won't jump to another video as you scroll

PRIVACY
Loop Master does not collect, transmit, or sell any personal data. All settings are stored locally in your browser using the standard storage API and never leave your device.
