# Android reads the background clipboard via AccessibilityService

Android 10+ blocks background apps from reading the primary clip, which breaks
the "send local copy to desktop" half of bidirectional sync. We use an
AccessibilityService to read the clipboard in the background; if the user denies
it, the app degrades gracefully to receive-only plus manual send (share/quick
tile). Applying a received clip via `setPrimaryClip` needs no extra permission
and always works.
