Apple only has one permission level for keyboards that send stuff over the network: full permission.  There&#x27;s no way to determine what exactly they send using apple&#x27;s keyboard permissions API, and apple doesn&#x27;t know what they send.  They just know it&#x27;s a keyboard that <i>can</i> send anything you type over the network, and warn you accordingly.<p>You have to either trust that google isn&#x27;t flat-out lying, or try to MITM and analyze the traffic using something like wireshark, which would be difficult assuming it&#x27;s properly encrypted.
