Privacy policy

Plume Worlds for Apple Vision Pro, by 100 Vision Apps. Last updated: 19 October 2026.

The short version: Plume Worlds collects nothing. No accounts, no analytics, no ads, no tracking, and no network use. Your hands, your room and your worlds stay on your device.

What we collect

Nothing. Plume Worlds has no accounts, no analytics, no advertising and no crash-reporting service of our own, and it includes no third-party code that collects data. We do not know who uses the app or what you build.

What the app uses on your device

Your hands. Hand tracking turns your hand movements into strokes and building pieces. It is processed on your device while you use the app, and it is not stored or sent anywhere.

Your room. World sensing finds your tables and floor so pieces can stand on them and cast shadows, and keeps your world in place. It is processed on your device; we never receive pictures or maps of your room.

Styluses and controllers. If you connect one, its position is used for drawing, on your device only.

Your worlds. Sketches are saved only in the app's folder on your device, which you can see in the Files app. A sketch leaves your device only if you share or export the file yourself. The app has no iCloud sync. Device backups are controlled by your system settings and by Apple, not by this app.

Your settings are kept in the app's preferences on your device.

Diagnostics. Help → Copy diagnostics copies a short technical report to your clipboard. Nothing is sent; if you paste it into a message to us, you choose what to share.

Permissions

The system asks for your permission before the app can use hand tracking, world sensing or an accessory. You can change these choices in Settings.

TestFlight and Apple

If you test the app through TestFlight, Apple runs TestFlight and handles your invitation, account details and any feedback or crash reports you choose to send, under Apple's terms and privacy policy. If you choose to share analytics with developers in your system settings, Apple may pass some of that to us; we see only what Apple provides.

This website

This website has no analytics, cookies or trackers. The company that hosts it may keep ordinary server logs, as any web host does.

Children

The app does not collect information from anyone, including children. It has no accounts and no online features.

Open-source credits

Plume Worlds includes code and assets from the open-source Tilt Brush project (Apache License 2.0, Copyright 2020 Google LLC), and sample sketches by community artists under Creative Commons licences, credited in the app (Help → Acknowledgements).
