Like many other things, there are a lot of nice typography available, which are free to use. There is no hidden spying on you or hidden charges or anything hidden, in the name of free.
I would like to mention, the two types, which are used in the theme Elegant for Wintersmith.
Kaushan Script and TeX Gyre Adventor
I found these fonts at fontsquirrel.
Elegant is a free as in air, theme, and encourage you to take it, hack it and use it, for whatever reason you may want it to use.
Happy hacking.
