Move 3D models and the mouse with your bare hand. Raise your hand in front of the webcam,
or of your phone, and turn, pan and zoom a 3D scan without touching anything: useful when
your hands are busy, gloved or not clean. The hand is tracked on your device and the video
is never recorded or sent anywhere.

## Not a medical device
Leviate is a 3D viewer. It is not a medical device and it is not meant for diagnosis,
treatment planning or any other clinical decision. Always check scans in the software
approved for that purpose.
## Privacy
The video stream and your scans are processed only inside your browser. Nothing is
uploaded, there is no tracking and no account. The only outside services are the ones of
**Use phone** (the PeerJS broker and a STUN server of Google), which see the connection
details but never the video. Leviate for Chrome and the Dentra plugin keep the video on the
computer in the same way. Full details in the [privacy policy](https://vladpereverzyev.github.io/leviate/privacy).
## Code signing
The downloads are built from this repository by the
[Build & Release](.github/workflows/build.yml) workflow. The macOS dmg is signed with the
Developer ID of the author and notarized by Apple; the Windows installer is not signed yet. The
copies from the Mac App Store, the Microsoft Store and the Snap Store are signed by those stores.
## Use of AI
Parts of Leviate, its code, its documentation and its packaging for the app stores (among them
the Linux files in `desktop/packaging/linux/`: the desktop entry, the AppStream metainfo and the Flatpak
manifest, and the snap recipe in `snap/`), were written with the help of generative AI tools. Every part was reviewed, tried
and is maintained by the author, who is responsible for it.
