If you only want to hide events from e.g. your history, take a look at the [`history` component](/components/history/). Same goes for logbook. But if you have privacy concerns about certain events or neither want them in history or logbook, you should use the `exclude`/`include` options of the `recorder` component, that they aren't even in your database. That way you can save storage and keep the database small by excluding certain often-logged events (like `sensor.last_boot`).
