Cookie Policy

Cookies are small files that help a website remember useful details about your visit. At 21Dukes Casino, they support the account, game, and promotional features you rely on, and they help us understand how the site performs so we can improve it. This Cookie Policy explains what we use, why we use it, and how you can control it.

Why Cookies Matter for Your Casino Experience

Without cookies, you would have to sign in again on every page, and the site would have no way to remember your preferred language or keep your game lobby settings in place. Cookies also help protect your account by flagging unusual activity and confirming that a session belongs to the right person. Think of them as the quiet background work that keeps everything running smoothly, so you can focus on the games.

What Cookies Are and How They Work

A cookie is a text file stored on your device by your browser when you visit a website. Each cookie usually contains a small piece of data, such as a random identifier, that the site can read on later visits. Some cookies disappear when you close your browser, while others remain for a set period or until you delete them.

Cookies themselves do not contain your password or payment card details, and they cannot access other files on your device. They work only with the information the site chooses to store in them.

Essential Cookies That Keep the Site Running

Essential cookies are required for the basic operation of 21Dukes Casino. They allow you to log in, keep you signed in during a session, route you to the correct part of the site, and process actions you request, such as opening a game or moving through a deposit page. The site cannot function properly without them, so they cannot be switched off through our cookie settings.

These cookies also support security. They help identify repeated failed login attempts and other patterns that may signal account takeover or misuse.

Functional Cookies for a Smoother Experience

Functional cookies remember the choices you make to tailor your visit. These may include your language, currency display preference, or whether you have already dismissed a notice. They can also keep your place when you leave a page and return to it later.

Because these cookies improve convenience rather than core operation, you may be able to limit them through your browser or our preference options. Doing so may mean that some settings need to be chosen again on future visits.

Performance and Analytics Cookies

Performance and analytics cookies show us how visitors use the site. They help us measure which pages load quickly, where people encounter errors, and which sections of the site get the most traffic. This information helps us fix technical problems and make navigation clearer.

The data gathered by these cookies is generally reported in aggregate form. It is used to understand overall trends rather than to identify individual visitors for unrelated purposes.

Marketing Cookies and Promotional Tracking

Marketing cookies help us understand whether our promotions reach the right audience and whether they are working as intended. For example, they may show whether a visitor arrived through an offer page and later completed a qualifying action, such as a deposit. They may also help manage how often a particular promotion appears.

Promotional codes, such as cashback offers that use a specific code, may rely on cookies to confirm eligibility. Bonus terms, including minimum deposits, wagering requirements, and country restrictions, always apply regardless of how a promotion was accessed. Certain promotions are not available to players in every country, and eligibility is set out in the relevant promotional terms.

Third-Party Services That May Set Cookies

Some cookies on our site are placed by third-party services that we use to operate features such as analytics, customer support tools, payment processing, and content delivery. These providers may set their own cookies, which are governed by their own privacy and cookie policies. We recommend reviewing those policies if you want more detail about how they handle data.

Payment providers and software suppliers may also use cookies or similar technologies during deposits, withdrawals, and game sessions. Our site may also load embedded content from external sources, and those sources may place cookies when that content is displayed. We select partners with the aim of protecting visitor information, but we do not control every technology a third party may use.

How to Manage, Block, or Delete Cookies

What Happens If You Turn Cookies Off

Disabling essential cookies will limit or prevent access to core features, including logging in, placing game sessions, and completing deposits or withdrawals. Turning off functional cookies may mean that your language, display, or other preferences are not remembered between visits. Blocking analytics or marketing cookies will not affect your ability to play, although it may mean that some offers are not displayed to you or that our site improvements take longer to identify.

If you change your cookie settings, the new choices will generally apply the next time you visit. Some changes may require you to sign in again.

Your Consent and Choices

Where applicable privacy laws require consent for non-essential cookies, we will ask for it before those cookies are set. You may accept or decline optional cookies through the preference options presented on your first visit, and you can change those choices later. Essential cookies do not require consent because they are needed to provide the service you request.

Withdrawing consent does not affect the lawfulness of processing that took place before the withdrawal. You are free to update your preferences at any time, and we will honor those choices in line with this policy.

Security, Fraud Prevention, and Account Protection

Cookies play an important role in keeping player accounts secure. They can help detect suspicious logins, identify devices that have been used in previous sessions, and support verification steps that protect your funds and personal details. We design these measures to reduce the chance of unauthorized access without making legitimate sessions unnecessarily difficult.

If you share a device with others, consider signing out after each session and clearing cookies when you are finished. This simple habit helps protect your account on public or shared computers.

Changes to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in our technology, service providers, or legal requirements. When we make significant changes, we will update the date at the top of the policy and may provide an additional notice on the site. Please review this page periodically to stay informed about how cookies are used.
