Cookie Policy
Last updated: August 15, 2026
1. What are cookies?
Cookies are small files stored on a user's device when visiting a website that allow preferences to be remembered and usage statistics to be gathered. On this site they are not used for advertising: no advertising cookie is set (see section 4). This site also uses similar technologies such as local storage (localStorage) to save game progress and records directly in the user's own browser.
2. Website owner
Owner: Miguel Arechaga
Tax ID (DNI): 72083190-V
Website: https://mundosudoku.com

3. Cookies used on this site
4. Third-party advertising
This website does not use any third-party advertising network or advertising cookies. The only advertisement that may appear — and only on the Spanish version of the site — is an own link, labelled as advertising in the footer, to tirasnasales.es: a static link that sets no cookies.
5. Consent
On the first visit, a banner is shown that lets you accept or reject non-necessary cookies. Analytics cookies are only used if the user gives consent: if consent is refused, the analytics tool is never loaded and no connection to the provider is made.
Withdrawing consent is as easy as giving it: users can change their decision at any time with this button, and the banner will appear again. It can also be done by clearing the site data from the browser settings (the decision is stored in the browser's local storage, not in a cookie).
6. How to disable cookies
Users can allow, block or delete cookies from their browser settings:
7. Policy updates
This policy may be updated due to legal or technical changes. The date of the last update appears at the top of this page. For more information about data processing, see the Privacy Policy.
