How anonymity works here. This page has no analytics. The form sends your text to a small script that stores only what you write and the date (not the time). The script does not read or store your IP address, browser information, or e-mail. The request does pass through Google's servers, as with any Google-hosted service. The source code is public, so you can check this. Specific details (a particular meeting, your writing style) can still identify you, so keep that in mind. Leave the contact field empty unless you want a reply.
