In short
ARSTEMA XR Lab collects, stores, and transmits no personal data whatsoever. It runs entirely inside the headset and never contacts any server, ours or anyone else’s.
Microphone
The app requests microphone access (RECORD_AUDIO) for one purpose: the voice assistant “Willy” accepts spoken commands such as “explain this part.”
- The microphone is open only while the talk button is held.
- Speech is recognized on the headset by an offline recognizer bundled with the app (whisper.cpp, ggml-tiny model).
- Recordings are never written to storage and never leave the device. Audio samples exist in memory only for the duration of recognition, then are discarded.
- No cloud speech service is used.
Data stored on the device
The app stores the following in its own directory inside the headset: session state (view mode, detached parts, language, sound switches) so you can resume your work; a frame-rate metrics file for local performance diagnostics; and the speech model extracted from the app package.
All of it is local, never read by ARSTEMA, and removed when the app is uninstalled.
Entitlement check
When installed from the Meta Horizon Store, the app verifies, through Meta’s platform service on the headset, that the signed-in Meta account owns it. That check is performed by Meta’s system; ARSTEMA receives, stores, and forwards no user identity from it.
What this app does not do
- No accounts, logins, or user profiles.
- No analytics, telemetry, crash reporting, or advertising.
- No tracking, advertising identifiers, or device fingerprinting.

- No online features, multiplayer, or social sharing.
- No camera access, passthrough, room scanning, or eye tracking.
- No network connection of any kind.
Children
This is a technical training tool and is not directed at children. Because no data is collected from anyone, no children’s data is collected.
