lumi — Cookie Policy

Version 1.0 · Effective 3 September 2026

This policy explains the cookies and similar technologies lumi uses.

Strictly necessary

lumi uses a small number of strictly-necessary cookies to keep you signed in and to protect the service (session and security tokens). These are required for the service to function and cannot be switched off.

What we do not use

The launch build does not load third-party advertising or cross-site tracking cookies. We do not sell or share cookie-derived data with advertisers.

Analytics

We do not deploy non-essential or third-party analytics cookies. Any performance telemetry collected is strictly limited to aggregate, essential service-operation purposes to maintain platform security and system performance.

Managing cookies

You can clear or block cookies in your browser settings. Blocking strictly-necessary cookies will prevent you from signing in.

Changes

We will publish any updated version of this policy on this page, with a new effective date.
