What Are Cookies
Cookies are small text files that are stored on your device (computer, tablet, or smartphone) when you visit a website. These files are widely used to make websites work more efficiently and provide information to website owners about how visitors interact with their content.
Cookies can be classified as “session cookies” which are automatically deleted when you close your browser, or “persistent cookies” that remain on your device for a specified period or until you manually delete them. Both types serve important functions in enhancing your browsing experience.
How We Use Cookies
We use cookies for various purposes across our website. Some cookies are essential for the basic functionality of the website and cannot be disabled without significantly affecting your ability to use our services. Other cookies help us improve your experience by remembering your preferences, analyzing how you interact with our website, and providing you with more relevant content.
Essential Cookies
Essential cookies are absolutely necessary for the website to function properly and cannot be disabled in our systems. These cookies are typically set only in response to actions you take that amount to a request for services, such as setting your privacy preferences, logging in, or filling out forms. You can set your browser to block or alert you about these cookies, but some parts of the website will not function without them. These cookies do not store any personally identifiable information.
We use two primary essential cookies on our website. The opus_cookie_consent cookie stores your cookie consent choice and is maintained for one year from your last visit. The opus_cookie_preferences cookie stores your specific preferences for different cookie categories and is also retained for one year.

We employ the opus_language cookie to store your language preference, allowing the website to display content in either Greek or English based on your selection. This cookie is stored for one year to ensure your preference is maintained across visits.

Analytics cookies allow us to measure and analyze how visitors use our website. All information collected by these cookies is aggregated and therefore anonymous.
