WinBig21 Cookie Policy
At WinBig21, we are committed to being transparent about the technologies we use on our website. This Cookie Policy explains what cookies are, how we use them on the WinBig21 online casino platform, what types of cookies we place, and how you can control them. By continuing to use our website at winbig21.casino, you consent to our use of cookies as described in this document. We encourage you to read this policy carefully alongside our Privacy Policy to fully understand how we handle your data.
What Are Cookies?
Cookies are small text files that are placed on your device — computer, smartphone or tablet — when you visit a website. Here at WinBig21, we use cookies to make our platform function correctly and to improve your overall experience. Cookies allow us to remember your preferences, keep you securely logged in, and deliver relevant content. They are widely used across the internet and are an essential part of how modern websites operate.
Cookies may be set by us directly (first-party cookies) or by third-party service providers whose tools we integrate into our platform. Both types may be used when you access the WinBig21 casino login page, browse our game lobby, or interact with our promotional content.
Why We Use Cookies
Our WinBig21 platform relies on cookies for several important purposes. We use them to ensure the technical functionality of our website, to analyse how visitors interact with our services, and to personalise the content and offers you see. Specifically, we use cookies to:
- Keep you securely signed in during your session after you complete the WinBig21 login process
- Remember your language preferences across our seven supported languages (EN, DE, FR, ES, IT, PT, JA)
- Store your preferred currency (USD, EUR, GBP, AUD, ZAR or cryptocurrency)
- Protect the security and integrity of your account and transactions
- Analyse traffic patterns and usage data to improve our site performance
- Deliver targeted promotional content, including information about our WinBig21 casino bonus codes and special offers
- Support our fraud prevention and responsible gaming monitoring systems
- Enable our live chat support functionality, available 24/7
Types of Cookies We Use
Strictly Necessary Cookies
These cookies are essential for our website to function properly. Without them, core services — such as the WinBig21 casino instant play feature, account authentication, and secure payment processing — would not operate. We do not require your consent to place strictly necessary cookies, as they are fundamental to the delivery of our services. These cookies do not collect any personally identifiable information beyond what is required to maintain your session.
Performance and Analytics Cookies
We use performance cookies to understand how visitors use our WinBig21 casino official website. These cookies collect aggregated, anonymised data about pages visited, time spent on site, and navigation paths. The information helps us identify areas for improvement and optimise the overall experience on our platform — whether you access us via desktop, the WinBig21 mobile casino, or browser-based instant play. We may use third-party analytics providers to process this data on our behalf.
Functional Cookies
Functional cookies allow our WinBig21 platform to remember choices you have made — such as your preferred language, region, or display settings — so that we can provide a more personalised experience on each visit. For example, if you have previously accessed the WinBig21 mobile casino login and set your interface to a particular language, functional cookies ensure those preferences are retained when you return.
Targeting and Marketing Cookies
At WinBig21 Casino, we may use targeting cookies to deliver promotional content that is relevant to your interests. These cookies track your browsing behaviour across our website and, in some cases, across third-party websites. They help us ensure that information about our WinBig21 promo codes, no deposit bonuses, free chips and other offers reaches players who are most likely to find them relevant. You may opt out of targeting cookies at any time using the controls described below.
Third-Party Cookies
Our WinBig21 website integrates tools and services provided by third parties, including game providers such as Rival, Betsoft, Spinomenal, Vivo Gaming and others. These third parties may place their own cookies on your device when their content is displayed. We do not control third-party cookies directly, and we recommend reviewing the privacy and cookie policies of those providers. We at WinBig21 are not responsible for the content or practices of third-party services embedded in our platform.
Cookies and Your Account Security
Security is a priority for us. Our WinBig21 Casino platform uses SSL4 / 128-bit encryption to protect all data transmitted between your browser and our servers. Session cookies used during the winbig21 casino login process are encrypted and expire automatically when your session ends. We do not store sensitive financial information in cookies. All payment transactions are handled through secure, encrypted channels, and our fraud prevention team monitors activity to protect all registered players.
How to Manage and Control Cookies
We respect your right to control the cookies placed on your device. You can manage your cookie preferences in several ways:
- Browser settings: Most browsers allow you to block or delete cookies through their settings menu. Please refer to your browser's help documentation for specific instructions.
- Opt-out tools: For analytics and marketing cookies, you may use industry opt-out tools such as the Network Advertising Initiative (NAI) opt-out page or Your Online Choices (YOC).
- Cookie consent banner: When you first visit our website, we present a cookie consent notice that allows you to accept or decline non-essential cookies.
Please be aware that disabling certain cookies may affect your ability to use some features of our platform. In particular, blocking strictly necessary cookies may prevent you from completing the WinBig21 login process or accessing the game lobby and payment functions.
Cookies and Promotional Offers
We use cookies to track eligibility for bonuses and promotional programmes. When you claim a WinBig21 casino no deposit bonus, WinBig21 free chips, or any other offer, cookies help us verify your eligibility, apply the correct bonus rules, and prevent duplicate claims. Our system uses cookies in conjunction with your registered account data to ensure that promotions — including our Cashtravaganza cashback, Weekly Raffle, daily tournaments, and Refer-a-Friend programme — are applied fairly and in accordance with our terms and conditions.
Players from certain jurisdictions, including Denmark, China, Japan, Poland and Israel, are subject to stricter promotional wagering requirements. We use cookies and account-level data together to enforce these requirements appropriately.
Data Retention
Different cookies are retained for different periods. Session cookies expire when you close your browser. Persistent cookies may remain on your device for a defined period — typically between 30 days and 24 months — depending on their purpose. We review our cookie durations periodically and update retention periods in line with applicable data protection standards. At WinBig21, we do not retain cookie data for longer than is necessary to fulfil the purposes outlined in this policy.
Changes to This Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in technology, regulation, or our own practices. When we make material changes, we will notify you through a notice on our website or via email if appropriate. We encourage you to revisit this page periodically to stay informed. Continued use of the WinBig21 online casino after any update constitutes your acceptance of the revised policy.
