Winner Island takes responsible gambling seriously. Certain strictly necessary cookies play a direct role in enforcing responsible-gaming controls on your account, including session time limits, deposit limits, cooling-off periods, and self-exclusion.

As a licensed operator, Winner Island is required to verify the identity of its players and to take reasonable steps to prevent fraud, money laundering, and the creation of multiple accounts. Certain cookies support these obligations by helping us recognise devices associated with registered accounts and by flagging unusual activity patterns. This processing forms part of our legal and regulatory compliance obligations and cannot be opted out of while you hold an active account with us.
Cookie data is retained for the duration specified in the tables above. Where cookies support the operation of your account or our compliance obligations, associated data may be retained for longer in accordance with our Privacy Policy and applicable legal requirements. Session cookies are deleted automatically when you close your browser.
We may update this Cookie Policy from time to time to reflect changes in the technologies we use, the services we offer, or applicable legal requirements. When we make material changes, we will update the "Last Updated" date at the foot of this page and, where appropriate, display a notice on winnerislandbet.nl or notify you by email. We encourage you to review this policy periodically to stay informed about how we use cookies.
