Cookie Policy
Last updated October 26, 2026
Cookies are small pieces of text a website asks your browser to keep. Browser storage (local storage and session storage) does a similar job. This page lists everything Brillix keeps in your browser, why, and for how long. It also lists the other servers your browser talks to when a page loads.
The short version
- Essential items keep you signed in, remember your theme and settings, protect sign-in, and take payments. They are always on.
- There are 2 optional items today: the YouTube music player and a page-visit signal for Brillix staff. They are off unless you choose Got it.
- Choosing Decline optional keeps only the essentials. Brillix works the same, except that music playback in the voice assistant asks you to allow the YouTube player first.
Your choice
Your choice is saved for 12 months in a cookie called bx_consent, with a copy in local storage. You can change it here or with the Cookie settings link in the sidebar and in Settings.
Essential cookies
These are set by Brillix. Without them you could not stay signed in or finish signing in safely.
bx_session
Keeps you signed in. Not readable by page scripts.
bx_anon
A random id for visitors without an account, so free-use limits and abuse protection work.
bx_org
Remembers which organization you were working in on the developer console.
bx_oauth_state
A one-time check that protects Google sign-in from forgery.
bx_consent
Remembers your answer to the cookie notice ("all" or "essential"). A copy is kept in local storage as the key bx-consent.
Essential browser storage
These stay in your browser. Brillix does not send them to other sites. Clearing them resets the matching setting.

Other servers your browser contacts
These are needed to show a page or to do something you asked for, such as paying or asking for the weather.
Stripe
Card payments. Stripe is loaded only when you open a checkout, and it sets its own cookies for fraud prevention.
Picture servers
Site icons (from Google), sports photos (from ESPN), logos (from Wikipedia) and some image style previews are fetched from the servers that host them. Those servers see your network address. Brillix sets no cookies for them.
Open-Meteo
When you ask for weather, your browser asks Open-Meteo for the forecast for a place. Brillix sets no cookies for it.
Optional items
These are not needed to use Brillix. They do nothing unless you chose Got it.
YouTube player
Plays music when you ask the voice assistant for a song. It loads a script from YouTube, which sets its own cookies. Brillix does not load it unless you chose Got it.
Page-visit signal
Each time you open a page, your browser tells Brillix which page it is (the address only, nothing you typed) so staff can see where visitors are on the live monitor. It is not sent unless you chose Got it.
What the servers record
Server activity log
For security, abuse limits and the staff live monitor, the servers record requests with your network address, an approximate place worked out from it, your account when you are signed in, and the time. Brillix has no advertising or marketing analytics in the web app.
Brillix does not run advertising or marketing analytics in the web app.
