How does uninstalling an app from your smartphone leave a hidden trace for analytics?

THROUGH SILENT PUSH NOTIFICATIONS AND HARDWARE IDENTIFIERS STORED IN THE SYSTEM.
Even after completely removing an app, developers can learn the exact uninstallation time and link the device upon reinstall. Analytics trackers use silent system requests and persistent storage tokens.

Detecting Uninstalls via Notification Services

Advertising SDKs send background silent push notifications to the device that are invisible to the user. When the Google or Apple server returns an error stating the app token is unavailable, the analytics platform logs the uninstallation event and links it to the user's ad profile.
