It's a kind of beautiful diary software with great function. There is often something written in one's day, such as ideas and work logs in one's work, and also some information needs to collect. We hope that there has some software to realize all above functions. Such is the intention of the KindDiary. KindDiary encrypts and compresses the data rigorously. KindDiary organizes data by means of XML structurally, and makes the old and new editions compatible preliminarily.
