Cookie policy
What the site stores in your browser, why, and how to change your choice.

What cookies are
Cookies are small text files a website stores in your browser. Some are needed for the site to work; others are set by third parties, such as advertising and analytics services.
Strictly necessary cookies
These are set without consent because the site cannot function without them. They do not track you.
| Cookie | Purpose | Provider | Lifetime |
|---|---|---|---|
cubimoon_consent | Remembers your cookie choice. | Cubimoon | 6 months |
NEXT_LOCALE | Remembers the language you picked. | Cubimoon | 1 year |
Advertising cookies
The site is funded by ads, so they are shown to every visitor. One ad network loads: the Yandex Advertising Network for visitors from Russia (detected by IP address, which is not stored), Google AdSense for everyone else. Cookie names and lifetimes are documented in the networks' own policies linked below.
Google AdSense: if you allow personalised ads, Google may set cookies to tailor ads to your interests, limit how often you see them and measure their performance. If you don't, Google serves non-personalised ads and is told not to use advertising cookies for them (Google Consent Mode).
Yandex Advertising Network: Yandex shows ads under its own rules and may set its cookies. You can turn off ad personalisation in your Yandex settings: https://yandex.ru/tune/adv
| Cookie | Purpose | Provider | Lifetime |
|---|---|---|---|
_gcl_*, IDE, test_cookie, … | Serving and measuring ads (Google). | Google LLC | Up to 13 months |
yandexuid, ymex, yabs-*, … | Serving and measuring ads (Yandex, visitors from Russia). | YANDEX LLC | Per Yandex's policy |
Analytics cookies
If you allow analytics (a separate choice from advertising), Yandex Metrica loads and sets cookies to count visits, tell new visitors from returning ones and see which pages and links are used. Session recording (Webvisor) is switched off. Without your permission Metrica is not loaded at all.
We also count page views with Plausible Analytics, which uses no cookies and stores nothing on your device: it counts visits without identifying you, so it needs no consent.
| Cookie | Purpose | Provider | Lifetime |
|---|---|---|---|
_ym_uid, _ym_d | Anonymous visitor id and the date of the first visit (Yandex Metrica). | YANDEX LLC | 1 year |
_ym_isad, _ym_* | Ad-blocker detection and session state (Yandex Metrica). | YANDEX LLC | From 30 minutes to 2 days |
yandexuid, yuidss, ymex, i | Set on Yandex's own domains when Metrica loads. | YANDEX LLC | Up to 1 year |
Changing your choice
Use the button below to reopen the settings. Turning analytics off deletes Metrica's cookies on this site and reloads the page without it. You can also delete cookies in your browser; the site will then ask again on your next visit. We ask again automatically after 6 months.
