Privacy Policy
The short version: camera video stays in your browser. We use the analytics and third-party services described below to improve Gesture Synth.
Camera & Hand Tracking
Gesture Synth uses your camera to track hand movements so you can play music. Camera processing happens locally in your browser. Your camera feed is not uploaded, recorded, stored, or transmitted by Gesture Synth.
When you close the tab or disable camera access, the video stream stops. You can revoke camera permission at any time through your browser settings.
Analytics
Gesture Synth uses Google Analytics, Microsoft Clarity, Plausible/Pageview, and Rybbit (analytic.app) to understand how visitors use the site and improve its reliability. These services are enabled by default but deferred until you interact with the page or a short fallback delay has elapsed, so they do not block the initial experience. The providers may process technical information such as your IP address, browser or device information, pages visited, and referrer information under their own privacy policies.
Camera video is not sent to analytics providers. You can manage analytics cookies and related storage through your browser settings or the applicable provider controls.
Accounts & Contact
The core Gesture Synth music experience does not require an account. If you voluntarily use an optional sign-in feature or email us for support, we process the information you provide to deliver that feature or respond to your request.
Advertising
Gesture Synth is applying to show ads served by Google AdSense. When advertising is active, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
You can opt out of personalized advertising at any time by visiting Google Ads Settings. You can also opt out of third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info/choices.
For visitors in the EEA, United Kingdom, or Switzerland, we present consent choices through Google Funding Choices, a Google-certified consent management platform integrated with the IAB TCF, before serving personalized ads, as required by Google's EU User Consent Policy.
Data Retention & Your Rights
Camera video is not retained by Gesture Synth. Analytics and infrastructure providers keep data according to their own retention settings and policies. If you have a privacy request, contact us and include enough information for us to identify the relevant request.
Depending on where you live, you may have rights to access, correct, delete, or object to certain processing of your personal data. Contact us with enough information for us to identify the relevant request. You may also manage analytics cookies through your browser settings or the applicable provider controls.
