Almost nothing. This site is served as static files from our own origin. It sets no cookies, runs no analytics, embeds no third-party scripts, fonts or trackers, and makes no requests to any service other than the one that serves it. There is nothing to consent to, so there is no consent banner.

Our hosting provider processes standard server logs (IP address, user agent, requested URL, timestamp) to deliver the site and defend it against abuse. These logs are held briefly, used for security and capacity only, and are not used to identify or profile visitors.

If you email us, we receive what you choose to send — typically your name, your address for reply, and the content of your message. We use it solely to correspond with you and to assess the work you bring to us.

The form on this site composes that email in your own mail client. Nothing you type is sent to, or stored by, this site; the message leaves from your mail client, to us, when you choose to send it.

Our lawful basis is legitimate interest: responding to the people who write to us. Correspondence is retained while it remains relevant to an enquiry or an engagement, then deleted. It is never sold, shared for marketing, or added to any list.

Under UK GDPR and the Data Protection Act 2018 you may ask what we hold about you, ask for correction or deletion, object to processing, and complain to the Information Commissioner’s Office (ico.org.uk). One email is sufficient; we answer within one month.

The site is served over HTTPS from our own origin. Correspondence is held on access-controlled systems. We practise what we sell: the fewer moving parts, the fewer ways to fail.

If this policy changes, the change appears on this page with a new date. This version: 6 September 2026.
