Cookies and analytics

Which cookies Skillok sets, which are required, which load only with consent, and how to change your choice at any time.

In this article

On your first visit a question about analytics appears at the bottom of the page with two equal buttons — Accept and Decline. Before you answer and after you decline, analytics does not load at all: only the required cookies below are used.

The rule is the same for every country: we ask everyone, not only where the law requires it. If your browser sends the Global Privacy Control signal, we treat it as a refusal and do not ask.

Your choice is stored in your browser with its date and the policy revision. When the rules change materially, we ask again.

Changing your choice#

The Cookie settings link in the site footer — or right here: Cookie settings — reopens the question. Declining after consenting takes effect at once: the page reloads without analytics and Metrica cookies are erased.

While you are signed in, Metrica does not load at all — neither in the app nor on public pages — and the cookie question is not asked.

Required cookies#

Sign-in, form protection and preferences do not work without them. They need no consent and take no part in analytics.

Name Purpose Lifetime
sk_access_token signing in until the session expires or you sign out
sk_refresh_token renewing sign-in; sent only to sign-in addresses 7 days or until you sign out
sk_session marker "sign-in can be renewed", holds no secret same as sk_refresh_token
sk_csrf protecting forms from request forgery 30 days
sk_flash a single message after an action ("Saved") one minute
skillok_lang chosen language one year
skillok_theme chosen theme one year

On the site some names carry the __Host- prefix: the browser then sends the cookie only to this domain and only over HTTPS.

Browser storage (localStorage) holds your theme and your answer to the cookie question — neither is sent to the server.

Set by Yandex Metrica, details in Analytics consent.

Name Purpose Lifetime
_ym_uid, _ym_d telling a returning visit from a new one one year
_ym_isad, _ym_visorc and other _ym_* counter service flags from the session to two days
yandexuid, ymex, yuidss browser identifier at Yandex (on Yandex's domain) up to a year
