Cookie Policy
Version 1.0 — Last updated: 2026-10-09. Operated by JOKR Labs.
This Cookie Policy explains which cookies, browser storage and third-party scripts the JOKR website (jokr.casino) and the JOKR Telegram app (together, the "Service") use, why, and how you can control them. It complements our Privacy Policy. The English version prevails over any translation.
Operator entity details will be published here upon completion of licensing.
1. What cookies and browser storage are
A cookie is a small text file that a website stores in your browser and reads back on later visits. Local storage and session storage are similar browser features that keep data on your device; session storage is cleared when you close the tab. "Third-party" items are set by another company's script or page, not by us.
2. Your choices on the website
When you first visit jokr.casino, a banner asks for your choice before any analytics or advertising script is loaded:
- Accept all — necessary items plus analytics and advertising partners;
- Reject non-essential — necessary items only;
- Settings — choose analytics and advertising separately.
Necessary items are always active because the Service cannot work without them. Your choice is stored for 12 months in the jokr_consent cookie; after that, or if you clear your cookies, the banner asks again. You can change your choice at any time with the Cookie settings button at the top of this page or in the footer of the sign-in screen. Withdrawing consent reloads the page so the partner scripts are no longer loaded; it does not affect processing that took place before.
You can also block or delete cookies in your browser settings. Blocking necessary cookies will prevent you from signing in.
Inside the Telegram app, JOKR runs as a Telegram Mini App: the analytics and advertising partners listed in section 5 are part of the Mini App (some quests rely on them), and the website banner is not shown there. Telegram's own data practices are described in the Telegram Privacy Policy.
3. Necessary cookies (always active)
| Name | Purpose | Duration |

jokr_web_session | Keeps you signed in on the website. Signed session token, not readable by scripts (HttpOnly, Secure). | 30 days, or until you sign out |
jokr_goauth | Protects "Continue with Google" against forged sign-ins (state, nonce and PKCE verifier, sealed). Sent only to the Google sign-in endpoints. | 10 minutes, deleted after sign-in |

Our infrastructure provider Cloudflare may set its own security cookies (for example __cf_bm) to filter automated traffic. They are necessary for the security of the Service and contain no information used to identify you for marketing.
4. Preference and functional items
| Name | Purpose | Duration |
|---|---|---|
NEXT_LOCALE (cookie) | The language you chose. | 1 year |
TG_USER_ID (cookie) | Your Telegram account ID, used to load your saved language. | 1 year |
twitter_* (cookies) | Set only if you link an X (Twitter) account to complete a social quest. | Up to 30 days |
| Local storage — preferences | Display currency, language, vibration setting, selected tabs, collapsed sections, pop-ups already shown. | Until you clear your browser data |

5. Analytics and advertising partners (website: only with your consent)
| Partner | Category | What it does |
|---|---|---|
Telegram Analytics (tganalytics.xyz) | Analytics | Audience measurement for Telegram Mini Apps (app opens, sessions). |
Sonar (static.sonartech.io) | Analytics | Audience measurement script. |
Taddy (sdk.taddy.pro, api.taddy.pro) | Advertising | Advertising and traffic-exchange network for Telegram Mini Apps; used for ad-based quests in the Telegram app. |
These partners may set their own cookies or browser storage and receive technical data such as your IP address, browser information and the pages you open. They process it under their own privacy policies. On the website, none of these scripts is loaded until you accept the corresponding category.
6. Sign-in providers and other services
- Telegram Login — the "Log in with Telegram" button is a widget served by Telegram (
telegram.org,oauth.telegram.org). Telegram may set its own cookies when you use it. The Telegram Web App script (telegram.org/js/telegram-web-app.js) is also loaded on every page so the same site works inside the Telegram app; we do not use it to set cookies. - Google — "Continue with Google" takes you to Google's sign-in page. Any cookies there are Google's own and governed by Google's privacy policy; we receive only the account identifier, e-mail address and name that Google shares with us.
- Game providers — when you open a third-party game, it runs on the provider's own page, which may use its own cookies.
- Fonts are served from our own domain; no request is made to a font provider when you browse the Service.
7. Changes and contact
We update this policy when the items we use change; the version and date at the top show the latest revision. For any question about cookies or your data: JOKR Support — the in-app support chat ("Contact support" in the footer of any main tab) or [email protected].
