Cookie policy and preferences
Last updated: 28/09/2026
This page lists every cookie and browser-storage item that the site, or a script it loads, writes — why, and for how long. Essential items always run; measurement and Google advertising run only after you consent, and you can change your choice at any time.
Change your choice
The choice is stored in this browser only. Withdrawing advertising consent after Google's scripts have loaded reloads the page to remove them.

Your anonymous identifier
If you consented to measurement, the browser stores a random identifier. To ask to see or delete the measurement data collected under it, include it in your request — it is the only way we can find that data, because we do not know who you are.
No measurement identifier is stored in this browser.
Delete data from this browser
Deletes the measurement identifiers, ad counters, cookie choice and display mode the site stored in this browser, and asks for your choice again. Game progress and high scores are not deleted by this button.
Browser controls
You can also block or delete cookies and storage in your browser settings. Blocking essential items may break the site and game progress. The site also honours "Do Not Track" for measurement.
