Cookie Policy
Last updated: August 6, 2026
This Cookie Policy explains how Century 21 NYC ("we," "us," or "our") uses cookies and similar tracking technologies on https://c21stores.com (the "Website"), and the choices you have. It should be read alongside our Privacy Policy.
What are cookies?
Cookies are small data files placed on your device when you visit a website. First-party cookies are set by us; third-party cookies are set by other companies whose services we use (for example, analytics or advertising providers). We also use similar technologies such as pixels, tags, and local storage, which we refer to collectively as "cookies" in this policy.
How you control cookies
When you first visit our Website, our cookie consent banner lets you Accept, Decline, or open Preferences to allow or reject non-essential categories individually. You can reopen these choices at any time from the cookie preferences link/button on our Website. Essential cookies cannot be rejected, as the site cannot function without them.
Global Privacy Control (GPC). We honor the Global Privacy Control browser signal. If we detect a GPC signal, we treat it as a request to opt out of the sale or sharing of your personal information for that browser and device.
"Do Not Sell or Share My Personal Information." Because we use advertising cookies that may constitute a "sale" or "sharing" under California and other US state laws, California residents can opt out via the "Your Privacy Choices" / "Do Not Sell or Share My Personal Information" link in our Website footer, or by rejecting advertising cookies in our banner. See our Privacy Policy for full details on your rights.
