Cookie Policy
1. What cookies are
Cookies are small text files a site stores in your browser. We also include here similar mechanisms (localStorage) used to store preferences.
2. Cookies we use
The site uses only strictly necessary and functional cookies:
- bc_sess — authentication (session) cookie. Holds a signed token, set with the HttpOnly and SameSite=Lax flags, with a lifetime of about 30 days. Logging into the dashboard is impossible without it. Strictly necessary.
- bc_lang — the chosen interface language (ru/en). Functional.
- bc_theme — the chosen theme (light/dark). Functional.
The language and theme values are also mirrored in the browser's localStorage so the page renders correctly without flicker on load.
3. What we do NOT use
The site has no advertising or third-party tracking cookies, social-media pixels or external web-analytics systems. We do not share your behaviour with ad networks. If analytics are added in the future, this policy will be updated and consent will be requested where required.
4. Managing cookies
You can delete or block cookies in your browser settings. Note: disabling the strictly necessary authentication cookie (bc_sess) will make dashboard login impossible. Functional cookies (language, theme) can be disabled without losing access — the site will use default values.
