Cookies
This document explains which cookies and similar technologies this site uses, what they are for and how to opt out. It complements the Privacy Policy.
1. WHAT COOKIES ARE
Cookies are small text files a site stores in your browser. Alongside them we use the browser's local storage, which works in a similar way but is not sent to the server automatically. Some of these files hold an identifier that lets the site recognise a returning visitor, which is why we ask for your consent before setting them.
2. WHICH FILES THIS SITE USES
The site carries no advertising or affiliate trackers. Only two kinds of files are used: one strictly necessary file that remembers your choice, and the files of the Yandex.Metrica analytics service.
| Name | Purpose | Retention | Set by |
| gc_cookie_consent (localStorage) |
Stores your cookie choice. Strictly necessary, so it is saved regardless of consent and does not identify you. | Until browser data is cleared | GeekChain |
| _ym_uid | Visitor identifier for Yandex.Metrica | 1 year | Yandex LLC |
| _ym_d | Date of the first visit | 1 year | Yandex LLC |
| _ym_isad | Whether an ad blocker is present | 2 days | Yandex LLC |
| _ym_visorc | Powers Session Replay — recording of on-page actions | 30 minutes | Yandex LLC |
| yabs-sid | Session identifier | Until the browser is closed | Yandex LLC |
| _ym_synced, _ym_retryReqs, _ym<counter id>_lsid (localStorage) |
Service data: synchronisation and retry of unsent requests | Until browser data is cleared | Yandex LLC |
3. LEGAL BASIS
Analytics files are set only after you press "Accept" in the banner shown on your first visit. Until then the Yandex.Metrica counter is not loaded and sends nothing. If you press "Decline", the counter never starts and any files left from earlier visits are deleted.
Declining does not restrict access: every section and the contact form work the same either way.
4. CHANGING OR WITHDRAWING CONSENT
You can change your choice at any time using the button below. Consent is withdrawn, the analytics files already set are deleted and the banner is shown again.
Your current choice: not determined.
Cookies can also be deleted or blocked in your browser settings, usually under "Privacy" or "Cookies and site data". Blocking cookies entirely may break other sites.
5. DATA SHARED WITH YANDEX
Yandex.Metrica is provided by Yandex LLC and processes data on our behalf. With your consent it receives de-identified visit data: pages viewed, referral source, device and browser type, IP address, and the on-page action recordings made by Session Replay. See the Yandex Privacy Policy.
