Cookie policy

Cookies are small records a site keeps in your browser. We use as few as possible, and here is what for.

Our cookies

cb_sess — the account sign-in session. Without it you would have to enter the password on every page. It lasts until you sign out; with «remember me» — longer.

cb_cur — the currency chosen for display. It remembers which currency to show prices in; payment is always in roubles.

cb_consent — your answer to the analytics banner, so we do not ask again.

cb_dev — the device marker. It lets the site recognise your browser: an account opens on no more than three devices, and from an unfamiliar one we ask for a code sent to your email. Lasts up to 400 days.

cb_claim — a temporary pass after buying without signing up: it lets you into the course right after payment without a password. Lasts two days.

Analytics cookies

After you agree in the banner, Yandex Metrica sets its own cookies to measure traffic. Until then it sets none: the counter does not load.

How to disable

Every browser can delete and block cookies in its settings. Without cb_sess, signing in will not work — everything else does not affect the site.

This translation is provided for convenience. The Russian version prevails.
