Answering your enquiry
When you send a message through the contact form, the details you give are used to respond to your enquiry, to route it to the right person inside our team, and to keep a record of the correspondence so a later reply has context. We do not use contact form data to send marketing messages, and we do not sell it to anyone.
If your message concerns a project, we may keep it alongside notes from the resulting conversation so the thread stays readable. That is the whole of the purpose: a reply, and a record of the reply.
Message details pass through our hosting and email providers only as far as needed to deliver and store the message.
