Summary

Gesture Synth Weld runs entirely in your browser. Your camera feed, hand data and audio never leave your device. We use cookies only for analytics and, if enabled later, advertising.

Camera & Audio

Camera access is via the Web APIs getUserMedia / MediaPipe Hands. If you use Keyboard Mode, no camera is used. Video frames and hand landmarks are processed locally. Recordings (audio/video/skeleton) are created locally with MediaRecorder and offered as a download — nothing is uploaded to our servers. If you enable the microphone for sing-along, audio is mixed locally into the recording.

Cookies & Analytics

Google Analytics 4 (GA4)

We use Google Analytics 4 (ID G-4TF2TBSZFT) to understand usage in aggregate (page views, events like recording or keymap changes). Google may set cookies like _ga / _ga_*. See Google Cookie Policy and opt out via Google Opt-out or your browser settings.

Microsoft Clarity

We use Microsoft Clarity (ID xv2860e4rz) for session and heatmap analytics to improve usability. See Microsoft Privacy Statement.

Google AdSense (serving, below the fold only)

We serve Google AdSense display ads (one manual unit per page, below the fold in the reading area). Google may use cookies (including the DoubleClick cookie) to serve ads. Learn more at How Google uses cookies in advertising. You can opt out of personalized ads at Google Ad Settings. See also /ads.txt for authorized sellers.

Data we do not collect

We do not run accounts, logins, or newsletters. We do not sell personal data. Camera and audio data stays on device and is not transmitted, stored, or shared by us.
