We use essential cookies to operate the site and maintain sessions — these do not require consent and cannot be disabled without breaking core functionality (like staying logged in). Everything else, including analytics (see below), is off by default and only activates if you click "Enhance Site" in the cookie banner shown on your first visit.
You can change or withdraw your choice at any time using the "Cookie Preferences" link in the site footer (or, if you have an account, in Settings), which opens the same preference center shown on your first visit. Withdrawing consent stops analytics from loading on any future page load; it does not retroactively delete data already sent to a provider before you withdrew.

Expiry values for Google and Yandex cookies are approximate — once their scripts load, those providers control that cookie's lifetime, not us.

We honor applicable opt-out signals where required by law. Browser Do Not Track signals are not standardized. We will update this policy if our handling changes.
