Privacy Policy

Local music, clear boundaries.

This policy explains what Gesture Synth processes in your browser, what third-party measurement or advertising services may receive, and the choices available to you.

Effective: July 30, 2026

Who and what this policy covers

Gesture Synth is an independent web project operated at gesture-synth.com. In this policy, “Gesture Synth,” “we,” and “us” refer to the operator of this website. This policy covers the website, browser instrument, analytics, advertising technologies when enabled, and messages sent to our support address.

The instrument does not require an account, payment, precise location, contacts, photo-library access, file-system access, or microphone access.

Your camera frames stay in your browser

Camera Mode asks the browser for camera permission only after you press Start Camera. Frames are processed in browser memory to estimate hand landmarks and control the synthesizer. Gesture Synth does not upload or store the camera feed or extracted landmarks on our servers.

Pressing Stop releases the camera stream. Closing the tab or page also ends the session. Your browser and operating system control the permission and may let you revoke it at any time. Mouse Mode does not request camera access.

Performance clips remain local unless you act

When you record a short performance, the visual output and synthesized audio are combined locally in the browser. Gesture Synth does not request microphone audio and does not upload the clip. The temporary preview remains in browser memory until you replace it, stop the session, reload, or close the page.

A file leaves the browser only when you choose Download or invoke a system share feature. At that point, your device, operating system, selected app, or destination service controls the copy you share. Review the destination service’s own privacy policy before posting.

Analytics used to understand and improve the tool

We use Google Analytics through Google Tag Manager and Pageview to measure visits and product interactions. Depending on the service and your settings, measurement data may include your IP address, approximate location derived from it, device and browser information, referrer, visited page, visit timing, and bounded events such as choosing an input mode, playing a first note, or completing a local recording.

Our product events do not intentionally include your name, email address, camera frames, recordings, raw hand landmarks, or free-form text. Analytics providers process data under their own terms, retention settings, and privacy controls.

Google and third-party advertising technologies

If advertising services such as Google AdSense are enabled on this site, Google and other third-party vendors may place or read cookies on your browser, use web beacons, or collect IP addresses and other identifiers to serve, measure, limit, and personalize ads where permitted. Google may use an advertising cookie to serve ads based on a visit to this site and other sites.

Where required, a consent message will let you manage advertising choices before personalized advertising is used. Consent choices may be stored so the site can remember them. We do not pass names, email addresses, camera data, recordings, or other intentionally collected personally identifying fields to Google in ad requests.

Learn more about how Google uses information from sites and apps and how Google uses cookies.

Your choices

  • Use Mouse Mode instead of Camera Mode, or deny/revoke camera permission in your browser.
  • Block or delete cookies and site data through browser settings. Some measurement or preference features may then work differently.
  • Manage Google ad personalization in Google Ads Settings.
  • Review industry opt-out information at AboutAds or Your Online Choices.
  • Use the consent message shown on the site where applicable to change advertising choices.

Information you choose to send

If you email us, we receive the address, message, and attachments you choose to provide. We use that information to respond, investigate a report, protect the service, or meet legal obligations. We retain support correspondence only as long as reasonably needed for those purposes.

Do not send passwords, government identifiers, financial information, or sensitive recordings. You may ask us to review or delete a support message, subject to security and legal retention needs.

Security, children, links, and changes

We use HTTPS and limit the instrument’s browser permissions, but no internet service can guarantee absolute security. Gesture Synth is a general-audience music tool and is not directed to children under 13. We do not knowingly request personal information from children.

Links or share destinations operated by others are governed by their own privacy practices. We may update this policy when the product, providers, or legal requirements change. The effective date above shows the latest material update.

Privacy questions

Contact with privacy questions or requests. Include enough context to locate your support message, but do not send additional sensitive information.
