What happens to your data on this site, in plain terms. The short version is that this site collects very little, because it is built not to.
The contact form sends nothing to a server
When you fill in the contact form, nothing is transmitted anywhere. The form assembles the text locally in your browser and opens it in WhatsApp or your own mail application. You send it yourself, from your own account, to us. No data reaches a server belonging to this site at any point.
