Luftig, in German, means Breezy, and that is what the company offers; a smooth and breezy experience. 

The logo is the benchmark of the user experience that gives the user a smooth and effortless experience.

Safe space gives the logo the attention it deserves. The ‘x’ marks the safe space around the logo. X is the height of the letter L in Luftig. The distance around the logo should always be observed according to the diagram.
