I was exploring something about indexdb ( a database inside browser).

However, we all know a local storage is also available on browsers apart from indexdb.

Most of the times , I want to use a volatile notepad in my mobile phone without uploading contents to any server . Also, I don't want to download any app.

So here is what I have created. You can try too.

https://devicenotepad.imfast.io

Your all contents are inside your browser's local storage. Nobody knows.

Also this site is hosted on Google drive using fast.io .

What else you can add: A service worker to catch the index HTML file and make it available when you are offline.
