Cookie Policy

Effective as of August 11, 2025

This Cookie Policy was created for a website operated by either ESET spol. s r.o. or any of its subsidiaries or partners, each of which is a separate legal entity and will be referred to as "ESET" or "We" in this Cookie Policy. As We use so-called "cookies" and similar technologies on our websites, We would like to be transparent about their use so all visitors can make informed choices regarding their own devices. This Cookie Policy is specifically focused on cookies.

What are Cookies?

Cookies are small text files that may be placed in your browser when you visit a website and then read if you visit the site again. Such information stored in cookies may be about you, your device or preferences, and they usually do not identify you directly. Some cookies are necessary so a website or a particular service can work properly and have an appropriate level of security. Some might be used for other purposes, for example, for website personalization, analysis of website traffic or for advertising of products or services online. We categorized all cookies We use based on their purpose, as detailed in the Categories of cookies We use section. In the Cookies used by this website section, we list individual cookies used by this website and provide more specific information on them, including what they are used for and their expiry.

Types of Cookies

In the following sections, We distinguish between "first-party cookies" or cookies that are set by ESET and "third-party cookies" that are set by ESET´s partners. Our partners are third parties who provide us with certain services for our website, usually analytical or marketing services. Moreover, We also distinguish between "session" cookies that are stored only for the duration of your browser session on our website and "persistent" cookies, that are stored for a longer time period as indicated below and therefore can be read even if you decide to visit our website again. The settings of third-party cookies are under the control of third parties.

Categories of Cookies We Use

Essential Cookies. These first-party cookies are necessary for the functioning and security of our website and the services you require. They are usually set in response to your actions to enable the use of certain functionality, such as remembering your cookie preferences, logging in or holding items in your cart. You cannot opt-out of these cookies. If you choose to block them via your browser, it may affect site functionality.

Analytical Cookies. These first and third-party cookies enable us to measure the number of visitors/users on our website. Moreover, they help us get insight into how you interact with our website and each service by enriching our datasets with data from third-party tools. We use them to improve our website, services, and user experience, locate and solve bugs or other problems with them, and evaluate our website traffic and campaigns' effectiveness. These cookies will only be stored in your browser if you grant us your opt-in consent. If you choose not to grant consent for analytical cookies, we will only have a limited possibility to monitor our site's or campaign performance.

Marketing Cookies. These third-party cookies allow our marketing partners to track your activities on our website, for example, when you download or buy our product. Those data is then combined with other data about you to build a profile relating to your interests and to show you more relevant targeted ads on other websites. Marketing cookies would be only stored in your browser if you grant us your opt-in consent. If you choose not to grant your consent, online advertising displayed to you will be less targeted to your needs or preferences.
