How It Works

Last updated: 11 August 2026

The camera

When you press start, your browser asks permission to use your camera. We use that feed only to detect where your hands (or, in the body-tracked games, your whole body pose) are, in real time, so the visual effects can react to them. The processing runs locally using Google's MediaPipe library and your device's graphics hardware. The video stream stays in your browser tab and is discarded as it plays — there is no recording feature, no upload, and no server that ever sees your camera.

The Anatomy Atlas is the one place the camera is off by default. Its 3D skeleton is mouse-driven and uses no camera at all; only when you press Live Motion does it ask for one. That mode tracks your body pose, your face mesh and your hands so it can name your own bones, joints, skull and muscles on screen as you move. All three trackers run on your device through MediaPipe, exactly as above — the video is drawn to a canvas, labelled, and thrown away frame by frame. Nothing is recorded or uploaded, and pressing stop (or leaving the tab) closes the camera immediately.

The microphone

Some toys (for example Water Ink and Hand Beats) ask for microphone access instead of — or as well as — the camera. The audio is analysed live in your browser for loudness and frequency (so a kick drum can be told apart from a cymbal) and the visuals react to that. The sound itself is never stored or uploaded, and it is not played back through your speakers. The analysis result is a handful of numbers that exist for a fraction of a second and are then gone.

The DJ Booth is the one exception, because singing through it is the point: with the mic switched on, your voice is pitch-corrected and played back live, and pressing REC keeps two bars of it so it can loop under the beat. That loop is held in the page's memory only — it is never written to disk and never sent anywhere, and clearing it, reloading, or closing the tab destroys it. Permission for the microphone is asked for once, on the start screen, together with the camera — but the mic starts muted: nothing is listened to, tuned or recorded until you switch it on inside the booth, and muting it again stops all of that.

What we collect

We use Vercel Web Analytics to count visits — aggregate, privacy-friendly numbers such as page views, rough location (country) and browser/device type, plus the site that referred you. We also log anonymous, aggregate usage events — for example which scene or filter was picked — so we can see which features are popular. It uses no cookies, stores no personal data, builds no profile of you, and does not track you across other websites. We have no accounts and no advertising. This analytics never sees your camera or your hand or body movements — those stay on your device, as described above.

The landing page shows an all-time visitor count. That is a single number kept in a hosted key-value database (Upstash) which our own server reads and increments on your behalf; your browser only ever talks to our domain. It holds no personal data and is not tied to you. Your browser also stores a small local flag so a repeat visit from the same browser is not counted twice.

Third parties

The main app and everything it needs (3D library, hand/body-tracking models, fonts, and the analytics script) is served from our own host, Vercel, on this domain. Like any website, Vercel's servers automatically receive standard request information — your IP address, browser type, and the time of the request — to deliver the page, and Vercel also provides the privacy-friendly Web Analytics described above. See Vercel's privacy policy.

Three of the toys are the exception. Hand Beats, Bubble Machine and the DJ Booth load their drawing and sound libraries (p5.js and Tone.js) from the jsDelivr CDN, and Hand Beats and Bubble Machine load their two display fonts from Google Fonts. Loading a file from those services means your browser contacts them directly, so they receive your IP address, browser type, and the address of the page you are on — the same standard request information any web server receives. They are content delivery networks, not trackers: no cookie is set and no account or profile is involved. Neither service ever receives your camera, microphone, or hand and body data, which never leave your device at all. See jsDelivr's privacy policy and Google's privacy policy. We load no other outside scripts, fonts, or trackers, and no advertising or analytics from anyone but Vercel.

Recording your own videos

HandScenes never records video, and the only audio it ever captures is the DJ Booth's in-memory vocal loop described above. If you screen-record yourself using it, that recording is created and stored by you, on your device or in whatever tool you chose — we are not involved and never receive it.

Children

HandScenes does not knowingly collect any personal information from anyone, including children.

Your rights

Because we don't collect or store personal data, there is nothing for us to access, correct, or delete on your behalf. You can revoke camera and microphone access at any time from your browser's site settings.

Changes

If we ever add features that change how data is handled (for example analytics or a built-in recorder), we will update this page before doing so.
