Thanks for trying it out! Honestly, no current idea of business model - this was just something I thought would be helpful in my daily workflow so I built it out.

The buttons are stored to localstorage, as is the editor text - everything stays locally (besides what is sent to the LLM). I'm planning on a simple import/export mechanism for transferring buttons across different browsers/computers!

It looks like the buttons are just stored in local storage. So in theory, they'll hang about until you clear that.
