Many current notes have account systems, etc. On the one hand, it solves the problem of data loss and backup, on the other hand, it increases our data security issues. After all, we do not want to keep some private data in the cloud. At this time, a local note-taking application without any network data transmission is needed. This application solves this problem perfectly. The whole application only has the read (import note) and write (export note) permissions of the file. You can rest assured that you do not have any network permissions, so if you encounter any problems, you can only feedback to us through the google market, and finally thank you for your support.
