This page explains how Puzzledoku uses cookies and similar technologies such as local storage.
Local storage (essential)
Our games save your progress and settings in your browser’s local storage, under keys that start with pd:. This is needed for the games to remember where you left off. It is never sent to our servers. You can clear it from the game’s settings or your browser’s site data settings.

Advertising
We don’t show ads yet. If we add them, advertising partners such as Google may use cookies to show and measure ads. Where the law requires it, we will ask for your consent before any such cookies are set, and we will update this page first.
Managing cookies
You can block or delete cookies in your browser settings. Blocking local storage will stop the games from saving your progress, but they will still be playable.
