Our Cookie Policy, Explained Plainly
When you visit blockchain-aud.com, small files called cookies are saved on your device. This page sets out exactly which ones we use, what each one does, how long it stays, and how you can refuse any cookie that is not essential. We keep the jargon out of it.
What Cookies Actually Do
A cookie is a small text file that a website places on your phone, tablet or computer when you load a page. The file holds a short string of letters and numbers that lets our servers recognise your device on your next visit. Cookies cannot read files off your hard drive, install software, or access anything else stored on your device.
We use them for practical reasons: keeping you logged in while you play, remembering that you picked English as your language, and understanding which pages load slowly so we can fix them. Without cookies, every page refresh would log you out and you would have to reset your preferences each time.
The Cookies We Set
Strictly necessary
These cookies keep the site working and keep your account safe. They handle your login session, confirm it is really you sending each request, and protect our payment pages against fraud. Strictly necessary cookies cannot be switched off through our banner, because the site and your account security depend on them.
Functional
Functional cookies remember choices you have made so you do not have to repeat them. They store your preferred language, your chosen currency out of AUD, BTC, ETH, USDT, USD and EUR, and your last game filters. Turning these off will not break the site, but you will need to reset your preferences every session.
Analytics
Analytics cookies collect aggregated data about how visitors move through the site: which pages get the most traffic, where players drop off during registration, and how long a game takes to load on a typical mobile connection. We look at this data in totals and patterns, not to identify you personally. You can decline analytics cookies at any time.
Marketing
Marketing cookies help us show our 150% welcome bonus up to AUD 16,000 with 100 free spins, our weekly cashback and our crypto race tournaments to people who might want them. They limit how often you see the same ad and measure whether an ad led to a visit. These are the easiest category to live without, and we only set them with your consent.
| Cookie name | Type | Purpose | Duration |
|---|---|---|---|
| bca_session | Strictly necessary | Keeps you logged in during your visit | Session (cleared on logout) |
| bca_auth | Strictly necessary | Verifies your account on each request | Session |
| bca_csrf | Strictly necessary | Blocks forged requests against your account | Session |
| bca_lang | Functional | Stores your language choice | 90 days |
| bca_currency | Functional | Remembers your display currency | 90 days |
| bca_anon | Analytics | Aggregated usage statistics | 30 days |
| bca_mrkt | Marketing | Ad frequency and retargeting | 90 days |
Third Party Cookies Explained
Some cookies on our pages are set by partners we work with, not by us. There are three categories we allow. Analytics providers measure site performance on our behalf. Advertising partners deliver our promotional campaigns and apply frequency caps. Payment providers set their own cookies on deposit and withdrawal screens so that transactions with Visa, Mastercard, Bitcoin, Ethereum or Tether are processed securely.
Each third party processes data under its own privacy policy as well as ours, and we only permit the categories listed above. We do not allow third parties to set cookies on our pages for any purpose we have not disclosed to you here. Blocking third-party cookies in your browser does not affect your ability to deposit, play or withdraw.
Control Your Cookie Settings
Our consent banner
The first time you arrive at blockchain-aud.com, our cookie banner appears before anything non-essential is set. You can accept all categories, reject everything except strictly necessary cookies, or open the settings panel and toggle analytics and marketing separately. We store your choice for 12 months, after which the banner reappears. You can also reopen the banner at any time through the "Cookie settings" link in the site footer and change your mind.
Browser controls
Every major browser lets you block or delete cookies yourself, regardless of your choice in our banner.
- Chrome: Settings, then Privacy and security, then Third-party cookies. Choose to block all or block only third-party cookies.
- Safari: Settings, then Privacy. Use "Prevent Cross-Site Tracking" and "Block All Cookies".
- Firefox: Settings, then Privacy and Security, then Cookies and Site Data. Set exceptions for our domain if you want to stay logged in.
- Edge: Settings, then Cookies and site permissions. Select "Block third-party cookies" to keep necessary cookies working.
What happens if you block cookies
Blocking strictly necessary cookies means the site cannot keep you logged in, so you would need to sign in again on every page, and some payment steps would refuse to complete for your own protection. Blocking functional or analytics cookies carries no penalty at all: you can still play any of our 16,900 games, claim bonuses and withdraw. Blocking marketing cookies simply means you see fewer, less relevant ads from us elsewhere on the internet.
How Long Cookies Last
Nothing we place on your device stays there forever. Session cookies vanish the moment you close your browser or log out. Persistent cookies carry an expiry date, and we keep those periods as short as the job requires. The table below shows every category at a glance.
| Category | Persistence | Removed when |
|---|---|---|
| Strictly necessary | Session only | You close the browser or log out |
| Functional | 90 days | Expiry reached, or you clear cookies |
| Consent record | 12 months | Banner reappears for a fresh choice |
| Analytics | 30 days | Expiry reached, or you withdraw consent |
| Marketing | 90 days | Expiry reached, or you withdraw consent |
| Third-party payment | Session only | You leave the payment page |
Changes to This Policy
When we add a new cookie, remove one, or change how long a category lasts, we update this page and post a notice on the site for at least 14 days before the change takes effect. If a change affects the cookies set on your device, the consent banner reappears so you can decide again. The version current at any moment is the one published here, so it is worth a quick look from time to time.
Questions about anything on this page? Our live chat runs 24/7, and you can also email [email protected]. We aim to answer cookie and privacy queries within one business day.
Frequently Asked Questions
Do you use cookies to track my gambling behaviour?
No. Analytics cookies record aggregated traffic patterns, such as page load times and drop-off points. We do not use analytics cookies to build a profile of your individual bets or playing habits.
Can I play at Blockchain Casino with all cookies blocked?
Not with every cookie blocked. Strictly necessary cookies handle your login and payment security, so those must stay on. Everything else, functional, analytics and marketing, can be switched off without affecting your ability to play.
How do I withdraw my consent after accepting?
Open the "Cookie settings" link in the footer of any page. Change your toggles, save, and we delete the affected cookies from your device on your next page load. Your account, balance and bonuses are untouched.
Do crypto deposits use cookies?
Our payment providers set session-only cookies on deposit and withdrawal screens to verify transactions. These expire as soon as you leave the payment page and are never used for advertising.
