From the developer:
Yank Note is an extensible Markdown editor. Applets, runnable code blocks, tables, PlantUML, Drawio, macro replacements, etc. can be embedded in the document. The data is saved as local Markdown files, and the extension functions are implemented in the original syntax of Markdown as far as possible. However, you can write your own plug-ins to expand the functionality of the editor. You can use encryption to save private files.
