Cookie Notice

BLUN uses only technically necessary cookies. No tracking cookies, advertising pixels, or Google Analytics are used on this surface.

What we set

• blun_sid — server session cookie used only after login. Lifetime: session.
• lc_lang — selected language preference. Lifetime: one year.

Legal basis

Both cookies are strictly necessary under Austrian telecommunications law and Art. 6(1)(f) GDPR because login, language selection, and secure sessions require them.

You can disable cookies in your browser at any time. Login functions may then be limited.
