Cookie Policy
Last updated: June 2026
This website does not use cookies. It sets none of its own and loads no third-party scripts that would set any. There are no analytics, advertising or tracking cookies.
So what's that notice about?
The cookie notice you may have seen is shown because being transparent about storage is good practice — even when, as here, there's barely anything to declare.
What is stored instead
The site keeps two small values in your browser's localStorage, which is
not a cookie: it is read only by the site, in your browser, and is never
sent to any server.
| Key | Purpose | Lifetime |
|---|---|---|
theme | Remembers your light/dark preference | Until you clear it |
fn42:cookie-notice | Remembers you've dismissed this notice | Until you clear it |
Because these are strictly necessary for a preference you set yourself and carry no personal data, no consent is required to store them.
Managing it
You can remove these values at any time by clearing your browser's site data for
fn42.dev. The site will keep working; it will simply forget your theme and
show the notice again.
