The site itself
Pages can be read without an account. A session cookie is used on the review form so the security token matches the browser that loaded the page.
Cookies
This site does not run an advertising cookie banner. These are the cookies that can be set.
hCaptcha
The review form loads hCaptcha. That widget may set its own cookies to tell a person from an automated send. The quote form does not use that widget.
Maps
Some pages embed a Google map. Google may set cookies when that frame loads. The map is there to show the area, not to advertise.
