Cookie policy
Last updated 23 October 2026.
A cookie is a small text file that a website stores in your browser. chilleren.com, the games on their own addresses, and id.chilleren.com use only the cookies they need to work. They use no cookies for analytics, advertising, or tracking, and they set no cookies from third parties.
Cookies we set
__Secure-Session
Where: chilleren.com, each game, such as sudoku.chilleren.com, and id.chilleren.com
Lifetime: 30 days
Purpose: A random identifier that ties your browser to a session on our server. The session keeps your game while you play without signing in, and keeps you signed in once you have. It also serves security: limiting the number of requests and protecting the services from denial-of-service attacks.
__Secure-Device
Where: chilleren.com, each game, and id.chilleren.com
Lifetime: 400 days
Purpose: A random identifier for your browser, which we use for security: limiting the number of requests and protecting the services from denial-of-service attacks.
Both are first-party, HttpOnly, and Secure cookies: only the site that set a cookie can read it, scripts in the page cannot, and the browser sends it only over an encrypted connection. Neither contains anything about who you are.
Why we do not ask for consent
The Danish Executive Order on cookies (cookiebekendtgørelsen) lets a site store information that is strictly necessary to provide the service you ask for without asking first. Everything listed here falls under that exemption, so neither the site nor the games show a consent banner.
Removing cookies
You can delete cookies at any time in your browser's settings. Deleting the session signs you out, and a game you are playing without signing in goes with it.
