Introduction

This document informs Users about the technologies that this Application uses to achieve the purposes described below. These technologies enable access to or storage of information (e.g., through the use of Cookies) on the User's device or the use of the device's data processing capabilities when the User accesses or runs this Application.

For simplicity, such technologies, unless there is a reason for differentiation, are defined as "Trackers" within this document.

For example, while cookies can be used in both web and mobile browsers, they are not applicable as browser-based trackers in mobile apps. Therefore, in this document, the term cookie is only used when specifically referring to that type of Tracker.

Some of the processing purposes for which Trackers are used require the User's consent. If consent is given, it can be freely withdrawn at any time using the procedure described in this document.

This Application uses proprietary Trackers (so-called "first-party Trackers") and external Trackers in connection with third-party services (so-called "third-party Trackers"). Unless otherwise specified within this document, such third parties also have access to the Trackers they manage.

The validity period and expiry of cookies and other comparable Trackers depend on the lifespan set by the provider or the respective third party. Some of these expire as soon as the User ends the browsing session.

To obtain more precise and up-to-date information on the lifespan, as well as other information - such as regarding the use of other trackers - Users are referred to the descriptions of the categories listed below, and furthermore, to the linked privacy policies of the relevant third-party providers or to contact the provider.

How this Application uses trackers.

Manage settings and give or withdraw consents

If the use of Trackers relies on consent, Users can give or withdraw this consent by setting or updating their preferences via the appropriate privacy selection panel on this Application.

How to control or delete cookies and similar technologies via your device settings.

Users can use their own browser settings to:

  • see which cookies or other similar technologies have been set on the device;
  • block cookies or similar technologies;
  • delete cookies or similar technologies from the browser.

However, browser settings do not allow for detailed control of consent by category.

For example, Users can find information on managing cookies via the most common browsers at the following addresses:

Users can also manage certain trackers used within mobile apps via appropriate device settings - for example, via device settings for advertising on mobile devices, or generally via tracking settings (users can access device settings and search for the corresponding commands).

How to opt out of interest-based advertising

Furthermore, Users are advised that they can follow the instructions provided by YourOnlineChoices (EU and UK), Network Advertising Initiative (US), Digital Advertising Alliance (US), DAAC (Canada), DDAI (Japan) or other similar services. Such initiatives allow Users to set their tracking preferences for almost all advertising tools.

The Digital Advertising Alliance provides the application AppChoices for controlling interest-based advertising on mobile apps.

However, it should be noted that Trackers help this Application provide Users with a better user experience and enhanced features (in accordance with the purposes described in this document). Therefore, if the User chooses to block the use of Trackers, the Owner may not be able to provide corresponding functions.
