Required for the site to work: session integrity, security, load balancing and remembering your cookie choice. They cannot be switched off, and the site will not function correctly without them.

After you choose Accept, the site uses Yandex Metrica for permitted public page views. When our own analytics is enabled, it runs alongside Metrica and follows the same choice.

Our own analytics records fixed page and action codes, event times, source/device/browser categories, scroll depth, approximate active time and fixed error codes. Events contain no form values, phone numbers, raw URLs, query parameters or fragments, messages or error text. Campaigns use only approved codes. Random browser and visit identifiers are not linked to form data or Boost ID.

We do not run advertising or cross-site tracking cookies, and we do not build advertising profiles or sell audience segments.

Open Manage analytics in the footer to change your choice. Necessary only stops new analytics collection and removes our identifiers and unsent events from this browser. You can also clear site data in your browser settings.

Our random browser identifier lasts up to 30 days; a visit ends after 30 minutes without events. Your cookie choice is stored until you change it or clear site data.

Events in our analytics working database have a retention policy of 30 calendar days using Moscow dates; aggregate counts without identifiers have a retention policy of 396 days. The counts do not provide unique visitors across multiple days. Restricted backups are used only for recovery and rotated separately after recovery is verified. Yandex Metrica retains data under its own service terms.
