This site uses only what it needs to work: your language, your accessibility settings, and the check that a form is being filled in by a person. There is no tracking and no advertising, and nothing is sent to anybody else.
Part of the site itself: which language you are reading, what you chose in the accessibility panel, the check that a form is being filled in by a person, and the map on the contact page. These cannot be switched off here — they are how the thing you asked for happens. What each one is, and what it does or does not keep, is listed below.
Language esyd.gr
Remembers whether you are reading the Greek or the English site, so that the front page sends you to the right one.
Accessibility settings esyd.gr
Remembers the contrast, text size and other choices you make in the accessibility panel. Written only after you change one of them, and kept in your own browser — it is never sent to the site.
Form security check (Cloudflare Turnstile) Cloudflare, Inc.
Checks that a form is being filled in by a person rather than a machine, so that the contact form cannot be used to send mass mail. It loads only once you start filling the form in — reading the page sends nothing — and your address is seen by Cloudflare at that moment.
Map (Google Maps) Google Ireland Limited
Shows where the offices are, on the contact page. The map is held by Google, so opening that page tells Google your address and which page you are reading. It is on every other page of this site that nothing is sent.
