Cookies Policy


ZEINCRO ("ZEINCRO," "we," "our," and "us" refers to the ZEINCRO group of companies as shown in https://www.zeincro.com/contact) sometimes places small data files called cookies on your device to which only our company has access to make this website work properly.

What are cookies?

A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.

Cookies are divided into different categories depending on the purpose they serve and the way they work. Our site uses "Strictly Necessary Cookies" and "Performance Cookies".

How do we use cookies?

Zeincro uses Strictly Necessary Cookies to help ensure that the website is able to function properly. These cookies are necessary and so are set automatically. You are not allowed to choose whether to reject the installation of these cookies, as without them, it would not be technically possible to provide services on behalf of Zeincro.
More analytically, our website uses the below Strictly Necessary Cookies:

Zeincro uses Performace Cookies and specifically Google analytics cookies for collecting information about how visitors use our website. Google Analytics cookies collect information that will usually not allow us to directly identify you. Google Analytics is a simple, easy-to-use tool that helps us measure how users interact with website content. As a user navigates between web pages, Google Analytics provides website owners JavaScript tags (libraries) to record information about the page a user has seen, for example the URL of the page.

When you visit our Website, we may record the URL you came from, IP address, domain types, your browser type, the country where your computer is located, the pages of our website that were viewed during your visit, and any search terms that you entered on our website. We also collect information such as the number of visitors to the site, where visitors have come to the site from and the pages they visited. We collect the above information for compiling traffic reports and for our own analytical purposes in order to enhance the performance of our website and our services. 

More analytically, our website uses the Performance Cookies as listed below:

The ga.js JavaScript library uses first-party cookies to:

  • Determine which domain to measure
  • Distinguish unique users
  • Throttle the request rate
  • Remember the number and time of previous visits
  • Remember traffic source information
  • Determine the start and end of a session
  • Remember the value of visitor-level custom variables

This library sets the following cookies:
