visionOS
visionOS is Apple's operating system for Vision Pro and future spatial-computing devices, built around gaze-and-pinch input and a strict on-device privacy model.
visionOS treats gaze as private by design: apps never receive raw eye-tracking data. Analytics for visionOS must respect that boundary, aggregate client-side, and pass App Store review without requesting unsupported entitlements.
The practical consequence is that visionOS analytics has to be reconstructed from indirect signals — pinch events, hand pose confidence, scene positioning — rather than from gaze vectors. Done right, this produces analytics that meet Apple's privacy bar while still surfacing the behavioural insights product teams need.
Why it matters
Vision Pro is the reference device for spatial computing. Analytics that respects visionOS's privacy model — never touching raw gaze, never leaking eye telemetry off-device — is what allows a studio to ship to the App Store without rejection while still measuring the metrics that matter for retention and comprehension.
Example
A productivity app on Vision Pro measures pinch-based interaction density and window positioning to understand which spatial layouts users adopt. No raw gaze data leaves the device, and the app passes App Store review on first submission.
