Privacy Policy
Last updated: September 1, 2026
The short version
3D Spatial Viewer runs entirely on your device. It does not require an account, and it does not collect, store, or share your personal data. The sections below explain this in more detail.
Information we collect
None. 3D Spatial Viewer does not ask you to create an account and does not collect personal information. We do not track you across apps or websites, and we do not use advertising identifiers.
Your 3D files
Every model you open — STL, OBJ, PLY, GLB, or USDZ — is processed locally on your device, whether that's Apple Vision Pro, iPhone, or iPad. Your files are never uploaded to our servers and are never shared with third parties. We have no access to them.
Spatial and sensor data
To place models at true scale in your room, the app relies on visionOS spatial features and your device's environment sensing (or, on iPhone and iPad, ARKit-based scene understanding). This information is used only on-device to position and render content. It is not recorded, stored, or transmitted to us.
SharePlay sessions
When you start a SharePlay session to review models together, your open models are sent directly to the other participants in that FaceTime session so everyone can view the same geometry — whether they're on Apple Vision Pro, iPhone, or iPad. This transfer happens through Apple's SharePlay framework between the devices in the call; we do not receive, store, or have access to the models being shared.
Analytics and third parties
The app does not include third-party analytics, tracking, or advertising SDKs. When you download the app, the Apple App Store may collect standard information under Apple's own privacy policy, which we do not control.
Data sharing
We do not sell, rent, or share personal data — because we do not collect it in the first place.
Children's privacy
3D Spatial Viewer is not directed at children under 13 and does not knowingly collect any information from them.
Changes to this policy
We may update this policy from time to time. Any material change will appear on this page with a new “Last updated” date.
