I may as well start with a small confession of my own. Even though it's harmless, it still is silly, but all the same, I like my privacy.
I like writing in code. A lot. Starting a Book of Shadows, I've used code and other languages to conceal what I've written. Not that there's anything necessarily bad in there, I just dislike the snooping of eyes.
I've written things in Aurebesh (Galactic Basic from Starwars) and, as of late been, have been using Norse Runic, but ever since I found this site with a handy alphabet, I've started coding my writing in the Dovahzuul font. Sadly the language isn't stretchable enough for me to want to write it in the proper manner, but I'm hoping it will scratch heads to figure out what the chicken scratch means when somebody eventually finds it.
