securememo.app for private, secure memos

Hello all!

I've been working securememo.app on my free time lately.

Service is for creating memos, you get URL for memo and password to decrypt it.

Encryption happens in client browser, password is shown to user but never send or stored on server.

Memos are deleted on read or after set expiration time.

It's open source, under MIT license. Runs on Cloudflare.

What you think? Is there room for such service.
