1. What cookies are

Cookies and similar things (localStorage, sessionStorage) keep small records in your browser: they help the site work and remember your choice. They cannot run programs or infect your device.

2. How we ask for consent

Technical ones are needed for the site to work and are set right away. Analytics ones are switched on only with your consent. On your first visit a banner appears with three buttons:

• Accept all. Technical and analytics cookies are switched on. The choice is saved and the banner does not come back.
• Only necessary. Only technical cookies work, no analytics is loaded.
• Decline. The same: no analytics, only technical cookies work.

«Only necessary» and «Decline» we remember until the end of the session, then the banner may appear again. Until you consent no analytics loads. There are no ads and no advertising trackers on the site.

3. Technical (needed to run the site, no consent required)

• sd_seen (sessionStorage). Marks that you have already seen the intro so it does not play on every page. Deleted when you close the tab.
• sd_cc (localStorage). Remembers that you pressed «Accept all» so we do not ask again. Kept until you reset the choice or clear the browser.
• sd_cc_s (sessionStorage). Remembers the «Only necessary» or «Decline» choice for the current session. Deleted when you close the tab, so the banner may appear again next time.

4. Analytics (only after consent)

Microsoft Clarity shows us which blocks people read, where they click and where they leave the page. It sets its cookies only after your consent.

• _clck (Microsoft Clarity). Links the actions of one visitor across visits. Kept for up to one year.
• _clsk (Microsoft Clarity). Groups actions within a single visit. Kept for about a day.

Clarity data is processed by Microsoft Corporation. You can read more about the service at clarity.microsoft.com.

5. How to manage cookies

You can change your choice in the banner at any time: click here and the banner comes back. You can also delete and block cookies in your browser settings. Technical cookies may be cleared, but the site stays fully usable without analytics cookies.

6. Changes

If the set of cookies changes, we update this list. The new version is published on this page.
