The short version: the words you type never leave your browser, and there are no accounts to create.
The generator
Word placement runs entirely in JavaScript on your device. The word list, the title and the layout never reach this server, and no copy of your puzzle is stored anywhere. If you share a link, the words travel in the part of the URL after the #, which browsers do not send to the server either.
What the server sees
Like any website, the server records requests: the page requested, the time, and the IP address. Those logs exist to keep the site running and to diagnose errors, and they are not used to build profiles.
The site is served through Cloudflare, which processes requests in order to deliver pages and block abusive traffic. No advertising or cross-site tracking scripts are loaded on these pages.
Cookies
The printable pages set no cookies of their own. The WordPress installation that publishes these pages may set a session cookie if you log in to the administration area — that is a staff login, not a visitor feature.
If you write to hello@wordfind.fun, your message and address are kept only to reply. They are not added to a mailing list and not passed to anyone else.
Children
This site is aimed at the adults who print the sheets. Nothing here is designed to collect information from children, and there is no account, comment or upload feature that a child could use to submit anything.
Removing data
Ask, and whatever is held — normally just an email thread — is deleted. Server logs roll off on their own schedule.
