Our Cookie Policy

This page explains every cookie we set when you visit 31betscasino.org.uk, why we set it, how long it stays on your device and what you can do about it. We keep the wording plain on purpose: you should not need a law degree to understand what happens in your browser when you play with us.

What Cookies Actually Do

A cookie is a small text file that a website places on your device when you visit it. Your browser sends that file back to us on every follow-up visit, so the site remembers things between page loads. Without cookies, the site would treat you as a complete stranger each time you clicked a new page.

Some cookies come from us directly. Others come from third parties whose services run on our pages, such as payment processors or analytics tools. Both types are covered on this page. Cookies are not programs, they cannot install software and they cannot read other files on your device.

  • Strictly necessary cookies: the site cannot function without them.
  • Functional cookies: remember your settings and choices.
  • Analytics cookies: show us, in aggregate, how the site is used.
  • Marketing cookies: help us show relevant offers instead of random ones.

Cookies We Use on 31bets Casino

Strictly necessary

These cookies keep you logged in, keep your session secure and protect our platform from abuse. When you sign in, an authentication cookie confirms it is really you on each page. A session cookie ties your bets, balance and game state together while you play. A security cookie helps us detect fraudulent login attempts and bot traffic. Strictly necessary cookies need no consent because the site simply does not work without them.

Functional

Functional cookies remember choices you have already made. If you set the site to English, a language cookie keeps it in English next time. If you close a promotion banner, a preference cookie keeps it closed. We also use one to remember your odds format in the sportsbook and another to store the state of the cookie banner itself, so we do not ask you the same question twice.

Analytics

Analytics cookies tell us, in aggregated form, which pages players visit, where they drop off and which links they never click. We use this to fix slow pages and improve navigation. The data is anonymised before it reaches our reports: we see patterns, not identities. These cookies only run with your consent.

Marketing

Marketing cookies support retargeting. If you viewed a promotion but did not claim it, these cookies let our advertising partners show you a reminder elsewhere on the web, with a frequency cap so it does not follow you forever. They also help us measure whether an advertising campaign brought in players who actually registered. Like analytics cookies, they stay switched off until you opt in.

Third Party Cookies Explained

We do not sell your data, and we do not let third parties place cookies on our pages at will. Three categories are permitted, each tied to a service we actually use.

Analytics providers measure site performance under our instructions, with data processing agreements in place. Advertising networks deliver and cap our retargeting campaigns; they receive a pseudonymous identifier, never your name, balance or betting history. Payment providers, such as Trustly, Skrill and Neteller, may set their own cookies on their secure pages when you make a deposit or withdrawal, because fraud checks and 3D Secure authentication depend on them. Those cookies fall under the payment provider's own policy, and we link to it during checkout.

Game studios whose titles run on our platform can also set technical cookies for load balancing and fair-play verification inside the game session. They cannot read your account details.

Manage Your Cookie Preferences

On our site

The cookie banner appears on your first visit. You can accept all categories, reject everything except strictly necessary cookies, or open the settings and toggle analytics and marketing separately. Your choice is stored in a functional cookie, and the "Cookie settings" link in our site footer reopens the panel whenever you want to change it. Withdraw consent at any time and the change applies from your next page load.

In your browser

Every major browser can block or delete cookies without our help. The routes below cover the four most common ones on desktop.

  • Chrome: Settings, then Privacy and security, then Third-party cookies.
  • Safari: Safari menu, then Settings, then Privacy, where you can block all cookies.
  • Firefox: Settings, then Privacy and Security, then Cookies and Site Data.
  • Edge: Settings, then Cookies and site permissions, then Manage and delete cookies.

What blocking changes

Blocking strictly necessary cookies will break core functions. Expect login failures, lost game progress, cart errors during deposit and repeated security checks. Blocking only analytics and marketing cookies costs you nothing in functionality: the site, the games and the cashier all keep working. Note that blocking our strictly necessary cookies can also log you out mid-session, which interrupts any active game round.

How Long We Keep Cookies

Every cookie we set has a defined lifespan, and the shortest one wins. Session cookies vanish the moment you close your browser. Persistent cookies carry an expiry date, after which your browser deletes them automatically. Nothing is stored indefinitely.

If you ask us to delete your account, all cookies linked to it are cleared in the same process. You can also clear them yourself at any point through your browser, as described above.

Updates to This Policy

When we add a new cookie category or a new third-party service, this page is updated and the "last updated" date at the top changes. For material changes, such as a new marketing partner, we also show the cookie banner again so you can review your choices rather than being carried over on old consent. Questions about anything on this page go to [email protected], where our team responds around the clock. 31bets Casino is operated by 31Bets N.V. under licence 8048/JAZ2021-195, and this policy was last reviewed in 2026.

Frequently Asked Questions

Do I need to accept cookies to play at 31bets Casino?

You need strictly necessary cookies, yes, because login, security and game sessions depend on them. Analytics and marketing cookies are optional and you can reject both in the banner while keeping full access to games, deposits and withdrawals.

How do I change my cookie settings after closing the banner?

Open the "Cookie settings" link in our site footer. The same panel from your first visit reopens, and you can switch analytics and marketing cookies on or off there. The new choice takes effect from your next page load.

Do cookies store my payment card details?

No. Card data is handled by the payment providers on their own secure pages and is never written into a cookie. Our cookies hold session identifiers and preferences only.

What happens if I delete all cookies?

You will be logged out, your saved preferences such as language will reset, and the cookie banner will appear again on your next visit. Nothing on your account itself is lost: balance, bonuses and history stay intact.
