Cookie Policy
Last updated: 14/11/2026
The short version
This site sets one cookie of its own, only when you sign in, and only for keeping you signed in. Reading the blog never sets any cookie of ours. With your consent (via the banner's Accept button), Google Analytics runs and Google may set its own measurement cookies — see the Analytics section below. Without consent, nothing loads and no analytics or advertising cookies are set. Your banner choice is stored in your browser's local storage, not a cookie.
The cookie we set
| Cookie | Type | Purpose | Lifetime |
|---|---|---|---|
PHPSESSID (session) | Strictly necessary | Keeps you signed in after Google Sign-In and protects the form you use against cross-site request issues | Session (deleted when you close your browser) |
Local storage
| Key | Purpose |
|---|---|
ck-ok | Remembers you dismissed the cookie banner (value: "1") |
theme | Your dark/light theme choice |
Analytics
We use Google Analytics (measurement ID G-NPZ0DY7134, in use since
November 2025) for aggregate audience measurement. The cookie notice
you saw on first visiting will have offered you an equal one-click
choice: Accept loads the analytics script; Decline loads
nothing and hides no content. With consent, Google sets its own
cookies (_ga* family) under
Google's Privacy Policy;
we configure IP anonymization and no cross-site tracking or
advertising. Changing your mind: clear this site's data in your
browser and the notice returns.
Third parties
The sign-in button loads Google's Identity Services script
(accounts.google.com/gsi/client) only on pages that contain a
comment/spark area. Google may set its own cookies when you click
the button; those are governed by
Google's Privacy Policy.
If you never sign in, nothing is loaded from Google.
Managing cookies
You can block or delete cookies in your browser settings; the site remains fully readable. Blocking the session cookie only disables sign-in, sparks, and commenting.
