The wizard and the planner are each one HTML file. They don't talk to a server. They don't keep what you type. Close the tab and it's gone.
This site is just files. The host can see that a page was fetched. It cannot see what you typed into the boxes.
Check me: turn the wifi off and use them anyway. View source and search for http, localStorage, indexedDB, fetch(. The wizard and planner don't have those. ChuuUpdate does, on purpose, after you click.
Copy the free HTML if you want. That's fine. ChuuWrite isn't on this site. Neither are tests.
No analytics. No accounts. No cookies from me. No ads today. If that changes, this page changes in the same edit.
