Cookie Policy

Version of November 11, 2026. Supplements the Privacy Policy.

This is an English translation provided for convenience. The binding text is the Russian version; in case of any discrepancy, the Russian version prevails.

Cookies are small records a website keeps in the browser. The website has no advertising cookies, and nothing is passed to advertising networks.

1. Cookies the website sets

• algo_session — keeps the user logged in after logging in with Telegram. Necessary. Lasts up to 30 days.
• algo_pending — remembers a login in progress while Telegram confirms it. Necessary. Lasts a few minutes.
• lang — the chosen website language (Russian, Uzbek or English). Preference. Lasts 1 year.
• algo_visitor — a random number and the time of the first visit, to tell repeat visits from first ones. First-party analytics, not accessible to page scripts and not shared with anyone. Lasts 1 year from the last visit.
• algo_ref — the number of the subscriber whose invitation link the visitor followed, so that the registration can record who invited them. Lasts 30 days.
• _ym_uid, _ym_d and other Metrica cookies — Yandex Metrica: visit counts and referral sources on the open pages, without session recording (Webvisor is off). Third-party analytics, under Yandex’s rules (https://yandex.com/legal/confidential/). Last up to 1 year.

Terminal settings (chart look, filters, layout) are kept in the browser’s storage or in the account on the server, not in cookies.

2. How to turn cookies off

Cookies can be deleted or blocked in the browser settings. Without algo_session you cannot log in to the Service; without the others the website keeps working, the visit is simply counted as a first one.

3. Why there is no cookie banner

The website sets no advertising cookies and does not track visitors on other websites. Necessary and first-party analytics cookies do not require prior consent, so the first screen is not covered by a notice.
