What we collect
This website has no user accounts and does not store form submissions. The enquiry form opens a pre-filled email in your own email app; we only receive what you choose to send. When you email us, we receive your name, email address, organisation and message.
If website analytics are enabled, we use them only to count visits and see which pages are read, in aggregate. Our web host may keep standard server logs (such as IP address and browser type) for security.
How we use it
We use your details only to reply to your enquiry and to continue the conversation you started, for example about investment, partnerships, pilots or research. We do not sell or rent personal data.
