The short version
This site collects one thing: the message you choose to send from the contact page. It has no mailing list and no visitor counting. It sets no cookies and stores nothing in your browser.
If you send a message
There is one form on this site, on the contact page. It carries your message to me so that I can reply, and it is handled by Formspree. It asks for your name, your email, what your message is about and the message itself. What you type there goes to me and is used to reply to you. Nothing else. Ask me to delete it, through this same form, and I will.
The typefaces come from Google
The three typefaces on this site are loaded from Google Fonts. So when a page loads, your browser asks a Google server for them, and Google can see your IP address. I do not ask for that and I receive nothing from it, but it is a third party your browser reaches because of this site, so it is said here.
If this changes
If this site ever starts to collect something, this page changes at the same time, not afterwards.
