kashif7230/priv ? reverse-engineered prompt

Build me a simple private notes app or data keeper that stores everything in a local text file, since this project is basically just a README and a data file right now.

I want a clean, minimal interface where I can add, view, edit, and delete saved entries without needing anything complicated. It should feel personal and lightweight, like something I can use to keep private information, quick notes, or small records. Make it easy to load and save the content from the existing data file, and if you need to, look up current docs online so you can pick the best way to handle file storage cleanly.

Keep the design simple and usable, and make sure the app works out of the box with clear basic instructions for running it. If there are any obvious improvements that make the experience smoother, go ahead and include them.
