1. What Are Cookies?

Cookies are small text files stored on your computer, smartphone, tablet, or other device when you visit a website or use an online service. Cookies help websites recognize your device, remember your preferences, improve functionality, maintain security, analyze performance, and provide a more personalized experience. Cookies may be Session Cookies (deleted when you close your browser) or Persistent Cookies (remain for a specified period or until deleted). We may also use similar technologies such as local storage, pixels, web beacons, and SDKs.

2. Types of Cookies We Use

Essential Cookies are necessary for the operation, security, and core functionality of the Services and generally cannot be disabled (e.g., authenticate users, maintain secure login sessions, remember essential account preferences, protect against fraud, enable payment processing). Performance and Analytics Cookies help us understand how users interact with the Services (pages visited, navigation paths, session duration, feature usage, device performance, error reports, aggregated statistics). Functional Cookies allow the Services to remember your preferences (preferred language, interface settings, accessibility preferences, region selection). Security Cookies help protect users and the Services (detect suspicious activity, identify fraudulent behavior, prevent unauthorized access, maintain platform integrity).

3. Third-Party Cookies

Certain trusted third-party providers may place cookies or similar technologies on your device, including payment processors, analytics providers, cloud hosting providers, customer support platforms, communication providers, security providers, and fraud prevention providers. Each third-party provider processes information in accordance with its own privacy policy. QuantoniumX does not control third-party cookie practices.

4. Managing Your Cookie Preferences

Most modern web browsers allow you to view, delete, or block cookies, block specific categories, configure preferences, and receive notifications before cookies are stored. Where required by applicable law, QuantoniumX provides mechanisms for obtaining and managing your consent for non-essential cookies. Disabling certain cookies may affect availability, security, functionality, or performance.

5. Legal Basis for Cookie Use

Where required by applicable law (including the GDPR and UK GDPR): essential cookies are processed on the basis of our legitimate interests; non-essential cookies (including certain analytics or functional cookies) are processed only with your consent where legally required. You may withdraw or modify your cookie preferences at any time.
