Cookies and local storage policy

Current public site

The site uses no advertising cookies, third-party analytics, session replay, or marketing pixels. Optional first-party analytics is technically available but remains disabled unless the site presents an accessible choice and the visitor explicitly selects “Allow analytics”.

Strictly necessary storage

The protected administration interface uses sessionStorage for a CSRF token within the current tab. The server session uses a secure cookie required for sign-in. Neither is used for advertising.

Optional first-party analytics

After explicit consent, rurchain.ru may set a protected random pseudonymous browser cookie and a short session cookie. It measures a normalized path without query/fragment, event type and time, language, acquisition source, coarse device category, and content interaction. Analytics does not retain IP, full user agent, full referrer, form values, email, or a browser fingerprint.

Proposed retention is up to 90 days for pseudonymous events/identity and up to 730 days for non-identifying aggregates. These periods are not production-approved until recorded by the operator. A necessary signed choice cookie may last up to 180 days and is not an analytics identifier.

Choice, withdrawal, and language

Reject is as easy as accept. No analytics request, identifier, or session is created before consent. The persistent preference button allows withdrawal at any time; withdrawal immediately stops collection and removes analytics cookies. Analytics consent is independent from subscriptions and message consent.
