A cookie is a small file the browser stores so the next page can remember something. roulcoin.com uses two cookies, both required for the site to work as an account.
1. Session cookie
After you sign in, roulcoin.com stores a session cookie. It is how the site knows the request belongs to your account. The wallet, the real-money table, Support and the account page need it.
The cookie lasts for the session the sign-in created. Signing out clears the signed-in state. If you delete the cookie in the browser, the next request asks you to sign in again.
2. Language cookie
The language cookie is named LOCALE. It stores the language you picked in the header or in the account. If you never pick one, and the site is allowed to detect the browser language, roulcoin.com chooses from the languages that are switched on. Otherwise it uses English, the default language.
The cookie stays until you delete it or you choose another language. It does not contain your name, email or balance.
3. What is not used
roulcoin.com does not set advertising cookies, does not follow you across other sites, and does not sell cookie data. Payment pages opened at a cashier are operated by that cashier under its own policy. Those pages are not part of roulcoin.com.
4. How to refuse
You can delete or block cookies in the browser settings. Blocking the session cookie stops sign-in. Blocking the language cookie means the site chooses the language again on the next visit.
