Cookies and what we keep in your browser

There are no analytics counters or advertising pixels on this site. We store three things, and each one is needed for the site itself to work.

Last updated: 4 August 2026

teora_src — where you came from

Set only if you opened the site through a tagged advertising link. It holds the tag itself and lives 90 days. When you leave an enquiry the tag travels with it, and we can see which page worked.

teora_admin — administration login

Appears only for the school team after a password is entered. Lives 14 days. It does not concern an ordinary visitor.

teora_sound and teora.name — your settings

Stored in your own browser, not with us: whether site sound is on, and the name you write under in the chat so you need not type it again. We do not see this.

What we do not have

No Google Analytics, no advertising pixels, no third-party counters. Video is embedded through YouTube in no-cookie mode and through Vimeo — they set their own once you press play.

How to remove it

Clear this site’s data in your browser settings. The site will keep working; it will simply forget your chat name and your sound setting.
