Cookies Policy
Four kinds of cookie, one of them you cannot switch off without breaking your login. Here is each one, what it does and how long it survives.

Nothing on this page tracks you across other websites. The affiliate cookie is the only one that remembers where you arrived from.
What a cookie actually is
A cookie is a small text file that our server asks your browser to keep and hand back on the next request. It cannot run, it cannot read your hard drive and it cannot see other sites you visit.
The reason casinos need them is boring: HTTP forgets you between clicks. Without a session cookie, every page load would log you out mid-spin.
We also use two close relatives — local storage, which keeps your interface preferences on your device, and pixels in email, which tell us whether a message was opened. Everything on this page applies to those too.
The cookies we set
| Cookie | Type | Does what | Lives for |
|---|---|---|---|
| Session | Necessary | Keeps you logged in between page loads. | Until you close the browser |
| Security token | Necessary | Stops a third-party page submitting forms as you. | Session |
| Currency and language | Preference | Remembers AUD versus USD, English versus French. | 12 months |
| Layout state | Preference | Remembers collapsed panels and your lobby sort order. | 6 months |
| Analytics | Analytics | Counts visits and which pages get read, in aggregate. | Up to 24 months |
| Attribution | Affiliate | Records which partner site sent you, so they get paid. | 30 days |
Strictly necessary cookies
These two are the price of a working account. The session cookie is what keeps you logged in; the security token is what stops another website submitting a withdrawal form in your name while you happen to be signed in.
Both are first-party, both expire when you close the browser, and neither is available to us for any purpose other than the one above. Block them and the site will still load, but you will not be able to stay signed in.
Preference cookies
These remember the choices you have already made so we do not ask twice: your account currency, your interface language out of the five we run, whether you had a panel open, how you last sorted the lobby.
Clearing them costs you nothing but a few clicks resetting the interface. They contain settings, not identity.
Analytics cookies
We count how many people reach a page, which routes they take through the lobby and where a journey breaks. It is aggregate: we look at a hundred sessions to find out that a button is confusing, not at yours to find out what you played.
Analytics data is separated from account data. If you decline analytics, nothing about your account or your play changes.
Affiliate attribution
Some players arrive from a partner site. When that happens, we set a cookie recording which partner, so that if you go on to open an account the referral is credited correctly.
It holds a partner identifier and a timestamp. It does not follow you around the web, it is not used to target advertising at you, and it expires after 30 days.
Controlling cookies in your browser
You are in charge of all of them, including the necessary ones. The route is much the same in every browser:
- Open your browser settings and find the privacy or site-data section.
- Choose whether to block third-party cookies, all cookies, or only cookies from specific sites.
- Use the per-site controls to clear what betjohn.org has already stored.
- Reload the page. If you blocked the necessary cookies, expect to be logged out.
On Chrome the path is Settings › Privacy and security › Third-party cookies. On Safari it is Settings › Safari › Advanced › Website Data. On Firefox, Settings › Privacy & Security › Cookies and Site Data. Private or incognito windows discard everything when you close them.
Changes to this policy
If we add a cookie, this table gets the new row before the cookie goes live, and the date at the top of the page changes. If we remove one, the row goes.
