btw I see I didn't address the most important point, A keylogger's whole job is to record or send what you type. FlicKey does neither. It keeps a tiny in-memory buffer of just the last few characters you typed (so it can delete-and-retype them when you fix a wrong-layout mistake), and that buffer is wiped constantliy, on every 'return", arrow key, click, shortcut, and app switch. Nothing is written to disk, and nothing is sent anywhere. No network calls at all. You can confirm that part yourself with Little Snitch/Lulu or by watching its connections, it'll have none..
