Cookie Policy

Cookies are small text files that a website stores in the user's browser when they visit it. They allow the site to remember your actions and preferences and to gather statistics. Similar technologies are local storage and web beacons (pixels).

A. Technical (strictly necessary) — always active, no consent required. They enable navigation, security and the operation of the site, and store your consent choice. B. Cookieless statistics — always active. Our own Umami counter runs on the school server, writes no cookies and collects no personal data. Under art. 22.2 LSSI-CE and the AEPD guidance, such measurement does not require consent. C. Third-party analytics — only with your consent. Google Analytics 4, Yandex Metrica and Microsoft Clarity write cookies and send data to their companies. Clarity additionally records cursor movement, scrolling and clicks to show how the page is used. This site uses no advertising or behavioural advertising cookies. Session recording (Yandex Metrica webvisor) is disabled, so what you type into forms is not recorded.

Technical (always): • Your banner choice — stored in the browser local storage under the key ylc-cookie-consent-v1 and never sent to the server. Cleared with the button on this page. Own Umami statistics (always, no cookies): • No cookies are used. Visitors are told apart by a temporary fingerprint made of the network address, the browser and a key that changes daily; a person cannot be identified from it. • Data is stored on the school server in Germany and is not shared with anyone. Google Analytics 4 (only with «Analytics only» or «Accept all»): • _ga — distinguishing visitors — up to 24 months. • _ga_K7HP9WNE3R — session state — up to 24 months. Microsoft Clarity (only with «Accept all»): • _clck — visitor identifier — 12 months. • _clsk — links actions within a session — 1 day. • CLID — identifier on the Clarity side — 12 months. • MUID — general Microsoft identifier — 13 months. Yandex Metrica (only with «Accept all»): • _ym_uid — visitor identifier — 12 months. • _ym_d — date of first visit — 12 months. • _ym_isad — ad-blocker flag — 2 days. • yabs-sid — session identifier — until the browser is closed. Names and durations are set by the providers and may change; up-to-date details are in their documentation.

The own Umami statistics and, with your consent, Google Analytics and Yandex Metrica record: • the address of the page opened and the address you came from; • the browser language and the language version of the site you chose; • device type, screen resolution, browser and operating system; • country and city, determined approximately from the network address; • time on the page and the order of moves between pages; • target actions: sending a request, completing the level test and the quiz, pressing the sign-up buttons, going to payment, clicks on the phone number and messengers. With «Accept all», Microsoft Clarity additionally records the session: cursor movement, scrolling and clicks. This shows where people get stuck on a page. Not collected and not recorded: the contents of form fields before submission, passwords, payment details, correspondence. The Yandex Metrica webvisor is disabled and Clarity masks typing into fields. Target-action records store the fact of the action, without its content. The data you send through the form (name and contact) is processed separately and described in the Privacy Policy.

• Google Ireland Limited / Google LLC — Google Analytics 4, Google Fonts. Data may be transferred to the USA under the Data Privacy Framework. Policy: https://policies.google.com/privacy • YANDEX LLC — Yandex Metrica. Data is processed on the company servers, including outside the European Union. Policy: https://yandex.com/legal/confidential • Microsoft Corporation — Microsoft Clarity: heatmaps and session recordings. Data may be transferred to the USA under the Data Privacy Framework. What you type into forms is masked on the Clarity side. Policy: https://privacy.microsoft.com • Umami — open-source software installed on our own server. There is no external provider and no transfer to third parties.

On your first visit a banner is displayed with three equivalent buttons: • «Accept all» — own Umami statistics, Google Analytics 4, Yandex Metrica and Microsoft Clarity. • «Analytics only» — Umami and Google Analytics 4, without Yandex Metrica. • «Decline» — only the own Umami statistics, which writes no cookies. Until you choose, Google Analytics, Yandex Metrica and Microsoft Clarity are not loaded: silence does not count as consent, and neither does closing the banner without choosing. Declining does not degrade the site. You can change or withdraw your choice at any time with the button on this page, or by clearing site data in your browser settings.

You can also block or delete cookies in your browser settings: • Chrome: Settings › Privacy and Security › Cookies • Firefox: Preferences › Privacy & Security • Safari: Preferences › Privacy • Edge: Settings › Privacy Disabling technical cookies may affect the operation of the site.

This policy may be updated due to regulatory changes or AEPD requirements. The current version will always be available on this page. Last updated: June 2026.
