* Google gives me crash reports, so I can fix them, but that's it

Back story:

One day my father asked me if I know a good notes application with data encryption, so that he can store his private stuff in it and trust it. I said I know some, but if he wants, I can write one. This is what I did, but decided to share it. This is a hobby project but I use it also myself.
