Nodex Privacy Policy

Last updated: April 8, 2026

Nodex is a Chrome extension that controls YouTube playback and browsing through head gestures detected via your webcam. This document describes exactly what data Nodex accesses, processes, and stores.

Summary

Nodex does not collect, transmit, or share any personal data. All processing happens on your device. No video, image, face data, or usage analytics leaves your browser.

What Nodex accesses

Camera

Nodex requests access to your webcam to detect head gestures via MediaPipe Face Mesh. Video frames are processed locally in your browser and are never saved, uploaded, or transmitted. The camera stream is discarded frame-by-frame as gestures are computed.

YouTube page content

Nodex reads DOM elements on youtube.com pages:

• The <video> element — to control playback (play, pause, seek, volume).
• Thumbnail anchors — to display the navigation focus ring and open videos.

Nodex does not read page content outside these elements. It does not access your watch history, comments, or account information.

What Nodex stores

Nodex uses chrome.storage.local to save (on your device only):

• Calibration profile: head pose baseline, personalized gesture thresholds from the calibration flow.
• Gesture-to-command mappings: which head gestures trigger which YouTube actions.
• UI preferences: HUD visibility, last used mode.

This data stays on your device. It is removed when you uninstall the extension or clear Chrome’s extension storage.

What Nodex does NOT do

• Does not collect analytics, telemetry, or crash reports.
• Does not use cookies or tracking pixels.
• Does not have a backend server — there is nothing to send data to.
• Does not share data with advertisers, data brokers, or third parties.
• Does not use remote code — all JavaScript and WASM is bundled in the extension package.
