ClipboardCollector
Passive collector for SignalCategory.Pasteboard.
Reports only clipboard metadata — whether a primary clip exists, its MIME types, its label and the sensitive-content flag (Android 13+) — via android.content.ClipboardManager and android.content.ClipDescription. It never reads clipboard contents.
Privacy: clip presence/timing and MIME types hint at user workflow; the actual clipboard text is intentionally not accessed. No runtime permission required.
