活用例

Input

(scan the enrolment QR on the device, then Add to Home Screen)

Output (abridged)

DEVICE ENROLLED -- 'Sales iPad'

  Posture      72 / 100  (medium)
  OS           iPadOS 18.2 -- current
  Storage      8% free    <- drags the score
  Battery      64%
  Last seen    2 minutes ago

  Low free storage BLOCKS OS updates, which is why it is scored rather
  than merely reported.

  Collected: battery, storage, OS/UA, activity, panic events.
  NOT collected: files, keystrokes, screen, location.

How it works

QR enrolment with a single-use, hashed, expiring token, then a service worker reporting posture.

Limits

Read live from the platform configuration.

Rate limit

30 requests / 60s (platform default)

Limitations — what it does なし do

A PWA, not an MDM. It reports what a browser can see -- it cannot enforce policy, wipe a device, or inspect other apps. It answers 'is this device healthy and alive', not 'is this device compliant'.

プライバシー

Posture signals are stored against the device record. No file contents, keystrokes or screen data are collected.

Standards
