There is no contact form and no published email address yet. The site is static and has no server to receive messages.
No inbox on this version
This page will name a way to write in when one exists. A question about a count or a formula is answered on the tool page, which states its rule. The privacy policy states what is not collected.
The tools never receive your draft, so there is nothing to send.
Security reports
If you believe a page is loading a script it should not, or that a tool is sending text off the device, this version of the site has no public address for that report. Check the page for a request that includes the draft, and do not put a real document in a text box while you look.
