Camera and microphone
The homepage does not request camera or microphone permission. The play page asks for camera access only after you choose to start the game. Gesture Synth requests video access and explicitly requests no audio, so it does not use your microphone.
Camera frames are read by the MediaPipe hand landmarker running in your browser. The Gesture Synth application does not upload or store your camera video. Leaving the play page stops camera access; you can also revoke camera permission in your browser settings.
Resources loaded from other providers
When hand tracking starts, the browser downloads MediaPipe runtime files from jsDelivr and a hand landmarker model from Google-hosted storage. These requests may expose standard connection information, such as your IP address and browser request details, to those providers. Gesture Synth does not send camera frames with those resource requests.
Local browser storage
Gesture Synth uses localStorage to remember whether you completed the play tutorial, so the guide does not reopen automatically on every visit. This preference stays in your browser until you clear site data. The current site has no user accounts.
Cookies and similar technologies
Gesture Synth and third-party services used by the site may use cookies, local storage, device identifiers, and similar technologies to operate the website, understand site usage, remember preferences, prevent abuse, and, when advertising is enabled, deliver and measure advertising.
Google Analytics may use cookies and similar identifiers to measure page visits, traffic sources, device and browser information, and interactions with Gesture Synth. You can control or delete cookies and other site data through your browser settings.
Analytics
Gesture Synth uses Google Analytics on production pages to understand aggregate site usage, such as page visits, traffic sources, device and browser information, and interactions with the play experience. Google Analytics may use cookies or similar browser storage and receives standard connection information such as your IP address as part of those requests.
Analytics is used to improve the site and understand whether visitors can successfully reach and use the product. For information about how Google handles data in its services, see Google's Privacy Policy.
Advertising and third-party vendors
Gesture Synth may use Google AdSense on eligible content pages such as guides and blog articles. When advertising is enabled, third-party vendors, including Google and its advertising partners, may use cookies, device identifiers, web beacons, local storage, IP address information, and similar technologies to serve, limit, personalize, protect, and measure ads.
Third-party vendors may use cookies or similar identifiers based on a visitor's previous visits to this website or other websites. Depending on your region, consent choices, and the advertising settings in use, ads may be personalized or non-personalized.
The interactive play page is intended to remain free of Auto ads so advertising does not interfere with camera controls or musical interaction. Where consent is required before advertising storage, identifiers, or personalization can be used, Gesture Synth will use an applicable consent mechanism. For regions covered by Google's publisher consent requirements, this includes a Google-certified consent management platform when required.
