• Messages you send us, so we can reply.
• Basic technical data, such as your network address, which our hosting provider processes briefly to deliver the site and keep it secure.

We don’t use advertising or tracking cookies on this site.

Who we share it with

• Cloudflare hosts the website. Cloudflare privacy policy.
• Google Fonts supplies the typeface, so your browser contacts Google to load it. Google privacy policy.

We never sell your data.

How long we keep it

We keep your email address until you unsubscribe or ask us to delete it. We keep messages for as long as needed to deal with them.
