How QFINHUB uses cookies and similar technologies
Last Updated: May 9, 2026
This Cookie Policy explains how QFINHUB (“we,” “our,” or “us”) uses cookies, local storage, and similar technologies when you visit our website or use our financial tools. It explains what these technologies are, why we use them, and how you can control them. By using QFINHUB, you consent to the use of cookies and similar technologies as described in this policy.
Cookies are small text files that websites store on your device (computer, tablet, or mobile) when you visit them. They are widely used to make websites work efficiently, remember your preferences, and provide a better browsing experience. Cookies can be “persistent” (remaining on your device until they expire or are deleted) or “session” (deleted when you close your browser).
Similar technologies such as local storage, session storage, and web beacons may also be used for analogous purposes. In this policy, references to “cookies” include these similar technologies unless otherwise stated.
QFINHUB uses a minimal set of cookies and local storage entries, all of which are strictly necessary for the operation and security of our platform. We do not use cookies for advertising, tracking across websites, or selling your data.
