The essential session
The PHP enquiry endpoint creates a session cookie when the contact form starts. It links the form to a security token and a short interval between submissions. The cookie contains an opaque session identifier, not your message.
Your practice work
Search-lab choices and proposal drafts remain in the current tab’s memory. They reset when the page is reloaded. A text download is created only when you press its download button; it is not an automatic backup.
Browser control
Your browser can clear or block site cookies. Blocking the form session may prevent the enquiry from submitting. The reading guides and practice tools do not need an advertising profile or third-party account.
See the privacy information for the separate record created when an enquiry is submitted.
