This site uses one optional cookie category: analytics. Nothing is stored and nothing is sent to Google until you accept it in the cookie banner, and you can change your answer at any time from "Cookie settings" in the footer.
With your consent, Google Analytics sets its cookies (_ga and _ga_*) to count page views and see where visitors arrive from. IP addresses are not stored by Google Analytics 4, and the data is only used to understand which pages are useful. Withdrawing consent deletes those cookies.
Your cookie choice itself is kept in your browser's local storage, not on a server.
When you send a message through the contact form, your name, email, company (if given) and message are stored so I can reply, and emailed to me. They are not shared with anyone else. Ask me at any time and I will delete them.
The server keeps short-lived technical logs (such as IP addresses) to protect the site from abuse.
