Privacy Policy

4D Vision collects no personal data. Nothing you do in the app leaves your device.

Last updated September 23, 2026

The app

This policy covers the 4D Vision app for Apple Vision Pro and this website, 4dvision.xyz.

• No data collection. The app does not collect, transmit, sell or share any personal information.
• No network connection. The app makes no network requests. It works fully offline.
• No accounts. There is no sign-in, and no in-app purchase.
• No tracking, ads or analytics. The app contains no advertising, analytics or third-party code, and it does not track you across apps or websites.

What stays on your device

To remember where you left off, the app saves a small amount of information locally on your Apple Vision Pro:

• your lesson progress
• how you arranged objects in the playground
• whether spoken narration is on or off

This information never leaves your device and is never sent to us. Deleting the app deletes it.

World sensing

In Worlds, the app asks for permission to use world sensing. It uses your head position so that walking around a 4D object rotates it. That information is used while you are in the space and is not stored or sent anywhere. You can say no. Every Worlds space still works, with an on-screen slider in place of walking. You can change this at any time in Settings on your Apple Vision Pro.

Narration

Spoken narration is generated on the device by Apple's built-in speech system. The app does not use the microphone.
