Glassbody — Privacy Policy

Effective date: 12 November 2026

Glassbody (“the app”, “we”) is an anatomy learning app for Android. This policy explains what the app does with information. In short: the app collects nothing. Everything happens on your phone.

The camera

Glassbody uses your phone’s camera to see where a person’s body, hands and face are, so it can draw anatomy over them. The camera picture is analysed on the phone only, frame by frame, by body-, hand- and face-tracking models that are built into the app (Google MediaPipe).

• The video is never recorded, saved, uploaded or shared.
• The tracking results (the positions of points such as shoulders, fingertips and the jaw) exist only in the phone’s memory while the app is drawing, and are thrown away immediately.
• Face tracking is used only to follow the opening of the jaw. It does not identify anyone, and no face data is stored or sent anywhere.
• The app does not use the microphone.

You can refuse or withdraw camera permission at any time in Android settings. Without it, the app can still show its built-in demo figure.

What we do not collect

• No accounts, sign-in or registration.
• No names, email addresses, phone numbers, contacts or location.
• No photos, videos or audio.
• No advertising, no advertising ID, and no analytics, tracking or crash-reporting services.
• Nothing is sold or shared with anyone, because nothing is collected.

What stays on your phone

The app remembers a few settings on the phone itself (for example display brightness, whether hand tracking is on, and whether you have already seen the first-run tips). These never leave the phone through the app. If you use Android’s own device backup, Android may include them in your personal backup to your Google account; that is controlled by you and Google, not by us. Uninstalling the app deletes them.

Internet access

The anatomy models and tracking models are inside the app, so it works offline. The app’s only use of the internet is opening the credit links on the About screen (for example, the BodyParts3D licence) in your web browser when you tap them.

Children

Glassbody is an anatomy learning app intended for teenagers and adults. It is not directed at children under 13, and it collects no personal information from anyone.

Not a medical device

The anatomy shown is one typical adult body from a research dataset, stretched to fit the person in view. It is not a scan of that person and must not be used for diagnosis or treatment.

Changes

If this policy changes, we will update it on this page and change the effective date above.
