1. What Cookies Are
Cookies are small text files stored on your device when you visit a website. They help sites work properly, remember your choices, and show owners how their service is being used.
Related technologies — local storage, session storage, and pixel tags — do similar jobs. In this policy, "cookies" covers all of them.
2. Why We Use Cookies

- Sign you in and keep you logged in securely across pages
- Hold your session and remember where you are in a flow
- Protect your account by spotting suspicious activity
- Monitor performance so we can keep things fast and reliable
- Understand usage through aggregated, anonymous analytics
- Remember preferences such as your currency and language

5. Managing Cookies
5.1 In your browser
Most browsers let you view, delete, and block cookies. Keep in mind that blocking strictly necessary cookies will stop the platform from working correctly.

5.2 Opting out of analytics
You can turn on "Do Not Track" in your browser — we honor DNT signals for analytics cookies.
6. Your Consent
By using CardCashTrade you agree to our use of cookies as described here. Strictly necessary cookies don't need consent because the service can't run without them. For non-essential cookies, we ask for consent where the law (such as GDPR/ePrivacy) requires it.
