This document informs Users about the technologies that help this Application to achieve the purposes described below. Such technologies allow the Owner to access and store information (for example by using a Cookie) or use resources (for example by running a script) on a User’s device as they interact with this Application.
For simplicity, all such technologies are defined as "Trackers" within this document – unless there is a reason to differentiate.
For example, while Cookies can be used on both web and mobile browsers, it would be inaccurate to talk about Cookies in the context of mobile apps as they are a browser-based Tracker. For this reason, within this document, the term Cookies is only used where it is specifically meant to indicate that particular type of Tracker.
Some of the purposes for which Trackers are used may also require the User's consent. Whenever consent is given, it can be freely withdrawn at any time following the instructions provided in this document.
This Application uses Trackers managed directly by the Owner (so-called “first-party” Trackers) and Trackers that enable services provided by a third-party (so-called “third-party” Trackers). Unless otherwise specified within this document, third-party providers may access the Trackers managed by them.
The validity and expiration periods of Cookies and other similar Trackers may vary depending on the lifetime set by the Owner or the relevant provider. Some of them expire upon termination of the User’s browsing session.
In addition to what’s specified in the descriptions within each of the categories below, Users may find more precise and updated information regarding lifetime specification as well as any other relevant information — such as the presence of other Trackers — in the linked privacy policies of the respective third-party providers or by contacting the Owner.

How to manage preferences and provide or withdraw consent
There are various ways to manage Tracker related preferences and to provide and withdraw consent, where relevant:
Users can manage preferences related to Trackers from directly within their own device settings, for example, by preventing the use or storage of Trackers.
Additionally, whenever the use of Trackers is based on consent, Users can provide or withdraw such consent by setting their preferences within the cookie notice or by updating such preferences accordingly via the relevant consent-preferences privacy widget, if available.
It is also possible, via relevant browser or device features, to delete previously stored Trackers, including those used to remember the User’s initial consent preferences.
Other Trackers in the browser’s local memory may be cleared by deleting the browsing history.
With regard to any third-party Trackers, Users can manage their preferences via the related opt-out link (where provided), by using the means indicated in the third party's privacy policy, or by contacting the third party.
Locating Tracker Settings
Users can, for example, find information about how to manage Cookies in the most commonly used browsers at the following addresses:
Users may also manage certain categories of Trackers used on mobile apps by opting out through relevant device settings such as the device advertising settings for mobile devices, or tracking settings in general (Users may open the device settings and look for the relevant setting).
How to opt out of interest-based advertising
Notwithstanding the above, Users may follow the instructions provided by YourOnlineChoices (EU and UK), the Network Advertising Initiative (US) and the Digital Advertising Alliance (US), DAAC (Canada), DDAI (Japan) or other similar services.
