1. What Are Cookies
Cookies are small text files that are placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and supply information to website operators.
Cookies can be "first-party" (set by the website you are visiting) or "third-party" (set by a service provider other than the website operator). Cookies can also be "session cookies" (deleted when you close your browser) or "persistent cookies" (remaining on your device for a specified period or until you delete them manually).
In addition to cookies, we may use similar technologies such as pixels, web beacons, and local storage to collect information about how you interact with our website.
2. Cookie Categories
We classify the cookies used on our website into the following categories:

Analytics Cookies
These cookies help us understand how visitors interact with our website by collecting and reporting information anonymously. They allow us to measure the number of visitors, see which pages are most and least popular, and understand how visitors navigate the site.
