The camera

The camera is off when you open a world. It starts only if you choose “Explore with your hands”, or if you turn it on later from the camera control or the C key.

The browser then asks for video from the camera facing you. The request does not include a microphone, and the picture is not shown on the page.

Frames are read in this page and passed to a vision task that also runs in this browser. That task looks for one hand and returns points. The model is a file on this website, and it downloads only after the camera starts.

This site’s code does not record that video, does not upload the frames or the hand points, and does not create an account.

What this browser remembers

A few choices are saved in local storage on this device, so the next visit can continue. None of them is a video or a trace of your hand.

Language

The language you pick with the switch.
synfield.locale

Landing motion

Whether the light on the home page is paused.
synfield.landing.motion

Last world and picture quality

The world you opened last, and a graphics setting. The camera and the sound are not saved: both start off.
gestureos.immersive.v1

Hand area

If you calibrate, the edges of the area your hand uses.
gestureos.calibration.v1

Hints

Which short hints you have already seen, and whether hints are on.
synfield.help.v1

Sensory preferences

Light, glow, trails, motion, light smoothing and volume. Sound and camera activation are never saved.
synfield.comfort.v1

Clearing this site’s data in the browser removes them. The application does not send these preferences with the visit count.

Visits and worlds

To know how many people visit and which worlds people enjoy most, the pages load Umami’s cookieless counter (cloud.umami.is). It counts page views and a few anonymous events: which world opens and how it was reached (link, Atlas, arrows, keyboard or hand), roughly how long it stays visible, in coarse ranges, whether a mouse, touch or hands are used, when the camera is turned on, and when a capture is made or shared.

Umami sets no cookies and creates no identifier that follows you across sites, and if your browser sends “Do Not Track” it counts nothing. SYNFIELD’s code never sends it video, camera images, hand points, gestures or the preferences above.

Fonts, world images and the vision model are files on this site. The credit at the bottom links to sandrabamboo.com. That site loads only if you follow the link.

When you stop or leave

Turning the camera off stops the video and closes the vision task. Hiding the tab does the same. Leaving the worlds, or closing the page, runs that cleanup as the page goes away.

The browser can keep its own record of the camera permission for this site. Changing or revoking it is done in the browser, not inside SYNFIELD.

Sound is separate. It stays off until you turn it on, it is generated in the browser, and it stops when you turn it off, hide the tab or leave.
