Cookie Policy

1. In short

Nidium uses technical cookies and browser storage (localStorage) so the site can remember your language and theme. The Yandex Metrica and Google Analytics counters are turned on only after you click “Accept” in the cookie notice. Visitors from Russia do not get Google Analytics at all. There are no advertising trackers.

2. What is stored

None of this identifies you, and none of it is shared with third parties.

• NEXT_LOCALE cookie: your site language (Russian or English), kept for up to 1 year.
• localStorage “theme”: light or dark theme.
• localStorage “cookie-consent”: your choice in the cookie notice (“all” or “necessary”).

2.1. Analytics (only with consent)

• Yandex Metrica (Yandex LLC, Russia): cookies _ym_uid, _ym_d, _ym_isad and others with the _ym prefix, kept for up to 1 year. Session Replay (scrolling, clicks, mouse movement; text typed into forms is not recorded) and click map are on. Data is stored on servers in Russia.
• Google Analytics 4 (Google LLC): cookies _ga and _ga_VEM464KYC6, kept for up to 2 years. Not loaded for visitors from Russia.
• What is collected: pages viewed, referral source, device and browser type, approximate country and city. Google shortens the IP address and does not show it to us.
• Why: to see which sections and articles are useful and to improve the catalog. The data is not used for advertising.
• Google servers are located outside Russia, so Google Analytics is turned off for visitors from Russia.
• Until you click “Accept”, Yandex Metrica is not loaded, and Google Analytics (except for visitors from Russia) runs in a limited mode: no cookies are set and repeat visits are not recognised.

3. Telegram and other sites

When you open a bot, mini app or external site from the catalog, their own rules and cookies apply. We do not control them.

4. Turning them off

You can change your analytics choice at any time with the “Cookie settings” link at the bottom of every page. You can also delete cookies and localStorage in your browser settings. The site keeps working; you will just need to pick the language and theme again.

5. Changes

If we add other cookies or services, we will update this page first and ask for consent where required.
