Privacy: what this site collects, and why

We use Google Analytics 4 to count visits and see which pages and tools are used. It records pages viewed (without any values in the address), approximate location, device and browser type, and interactions such as moving the map or copying a link. It sets cookies to do this. We do not send names, emails or form contents to Google.

You can block analytics with your browser's privacy settings, a content blocker, or Google's opt-out browser add-on.

When you send a form, we receive what you typed: for example your name, email, organisation and message, or a reference to a published study. It is stored on this site's host and emailed to the project inbox. We use it only to reply, to send the updates you asked for, or to review a submitted curve.

We do not sell or share it. Your network address is used briefly to limit repeated submissions and is not stored with your message.

To see, correct or delete what we hold about you, or to stop updates, write to [email protected]. We delete form submissions when they are no longer needed for the reason you sent them.
