Your controls

The banner acknowledges essential storage; it does not grant marketing permission. Marketing is a separate, optional choice. If optional trackers are introduced, they must remain off until you choose to enable them. You can reopen the storage notice from “Cookie settings” in the footer.

Clearing site data can remove pending scans. Sync first, then sign out or clear the device when appropriate.
