Our cookie policy and how we use them
Last updated: January 13, 2026
1. Introduction
This Cookie Policy explains how CitySpotlight Limited ("CitySpotlight", "we", "us", or "our") uses cookies and similar tracking technologies when you visit our website at cityspotlight.com or use our billboard advertising marketplace platform (the "Services").
This policy provides detailed information about what cookies are, what types of cookies we use, why we use them, and how you can manage your cookie preferences. This Cookie Policy should be read alongside our Privacy Policy, which explains how we collect and process your personal data.
2. What Are Cookies?
Cookies are small text files that are placed on your computer, smartphone, tablet, or other device when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and give website owners information about how their site is being used.
Cookies can be "persistent" or "session" cookies:
- Persistent cookies remain on your device for a set period of time or until you delete them. They are activated each time you visit the website that created them.
- Session cookies are temporary and are deleted when you close your browser. They only last for the duration of your visit.
Cookies can also be "first-party" or "third-party":
- First-party cookies are set by the website you are visiting (i.e., CitySpotlight).
- Third-party cookies are set by a domain other than the one you are visiting, typically by our service providers.
3. Similar Technologies We Use
In addition to cookies, we use other similar technologies:
3.1 Local Storage
HTML5 local storage allows websites to store data locally on your device. Unlike cookies, data stored in local storage has no expiration date and remains until explicitly deleted. We use local storage to save user preferences such as theme settings and language preferences.
3.2 Session Storage
Similar to local storage, but data is cleared when you close your browser tab. We use session storage for temporary data needed during a single browsing session.
