Cookie Policy

Last updated: 22.10.2026

This Cookie Policy explains which cookies and browser storage Lumen uses and why. Lumen is operated by Bruo Systems Limited, 2c Grangegorman Lower, Smithfield, Dublin, Ireland (Reg. 765033) ("we"). It should be read together with our Privacy Policy.

What we use

Lumen uses only strictly necessary cookies and browser storage, all set by lumen.deals itself. "Strictly necessary" covers sign-in, security, the language and currency you pick, and your cookie choice: the same single category shown as "Strictly necessary" in the Cookie preferences panel. We use no analytics, advertising or cross-site tracking cookies, and no non-essential cookies are set today.

Cookies:

  • __Secure-authjs.session-token: keeps you signed in. Set when you sign in; lasts up to 30 days, and is removed when you sign out.
  • __Host-authjs.csrf-token: protects the sign-in and sign-out forms against cross-site request forgery. Deleted when you close your browser.
  • __Secure-authjs.callback-url: remembers which page to return you to after sign-in. Deleted when you close your browser.
  • locale: the site language you chose. Set when you change the language; lasts 1 year.
  • currency: the currency you chose for prices. Set when you change the currency; lasts 1 year.

Browser storage (kept on your device, not sent to us):

  • ff-cookie-consent: your choice in the cookie banner or the Cookie preferences panel. Kept until you clear your browser storage.
  • lumen.failedRuns.seen: which failed renders you have already been told about, so the notice is not repeated. Signed-in pages only; kept until you clear your browser storage.

Your choice

On your first visit you can Accept or Decline non-essential cookies, or open "Manage cookies" for a panel that lets you turn non-essential cookies on or off directly. You can change your choice at any time from that same "Manage cookies" panel, reachable from the cookie banner, or from "Manage cookies" in the footer on every page, even after the initial banner has been dismissed. Essential cookies are always required for the site to function.
