Cookie Policy
Updated 29 July 2026
What cookies are
Cookies are small files a site stores in your browser to remember your actions and settings. We use cookies by the categories below. Strictly necessary cookies are always set (the site does not work without them); analytics cookies are set only with your prior consent, collected via the consent banner.
Cookie categories
| Category | Purpose | Duration | Consent |
|---|---|---|---|
| Session (strictly necessary) | Sign-in and keeping you logged in | Up to 30 days | Not required |
lang (functional) | Remembers your chosen interface language | Up to 1 year | Not required (needed for the feature) |
| Google Analytics (analytics) | Anonymized site-usage statistics | Up to 24 months | Consent only |
| Google Ads (advertising measurement) | Attributing a conversion to an ad click | Up to 90 days | Consent only |
Durations are the maximum set by the provider; actual lifetimes may be shorter.
Strictly necessary cookies
Session cookie. Set on sign-in, it stores the signed session (see the Privacy Policy). Sign-in and protected pages do not work without it, so it requires no consent (it falls under the "strictly necessary" exemption). Stored for up to 30 days or until sign-out.
Functional cookies
The lang cookie. Remembers your chosen interface language (RU/EN) so it isn't asked again. It is not used for tracking and is not shared with third parties.
Analytics cookies
We use Google Analytics for aggregated site-usage measurement. The Google tag loads with all storage permissions denied. Until you consent, it neither sets nor reads Analytics or advertising cookies; Google may receive cookieless pings such as the page URL, referrer, consent state and whether ad-click information is present, for aggregate reporting and modelling. Analytics and advertising cookies, and full measurement, activate only after your consent. Declining does not affect how the site works.
Advertising measurement cookies
Google Ads. Set only after your consent, they let Google see that a visit came from one of our ads, so we can tell which ads work. Stored for up to 90 days. We do not use them for profiling or personalised advertising: the ad_personalization signal stays switched off. Declining does not affect how the site works.
The widget on clients' sites
The search widget embedded on our clients' sites keeps a session identifier (sessionId) only in page memory and sends it with follow-up requests to continue the conversation. It is not stored in a cookie or localStorage and disappears when the page is closed or reloaded. The site owner remains responsible as controller for its own site disclosures; the allocation of responsibility is set out in the Data Processing Agreement.
How to manage and withdraw consent
You can change or withdraw consent to analytics and advertising-measurement cookies at any time via the "Cookie settings" link in the site footer — it reopens the banner with per-category toggles. Strictly necessary and functional cookies can be removed via your browser, but then some features (sign-in, remembering your language) may behave differently. Withdrawal takes effect going forward and does not affect processing before withdrawal.
Changes and contact
We may update this Policy when the set of cookies changes; material changes are reflected in the update date. Questions — via the contact form.
