Depending on the respective application (see above), cookies and similar technologies are used to identify users.
Cookies are small text files that contain a character string that can be used to uniquely identify a web browser or WebApp installation. Operators of websites and web apps or third parties store cookies on computers or mobile devices when they are used. Cookies usually expire after a certain period of time and are therefore automatically deleted. Some web browsers block the storage of cookies by default. For information on handling cookies, please refer to the help pages or the documentation for your web browser.
Local Storage stands for a technology that enables websites and web apps to save data on your computer or mobile device in the context of the browser. While this is similar to cookies, the local storage can hold larger amounts of data; however, its content is not transmitted to the web server with every request, but must be read out explicitly. Furthermore, the data is retained in the Locale Storage until the application or the user deletes it himself. For information on handling the local storage, please refer to the help pages or the documentation for your web browser.
SENSIC.net uses local storage entries named "sui" with a validity of 2 years.
File Cache stands for a technology that enables websites and web apps to save data on your computer or mobile device so that websites can be loaded more quickly the next time you visit them. The data is automatically deleted after the expiry date. For information on handling the file cache, please refer to the help pages or the documentation for your browser.
SENSIC.net uses the file cache via the URL "sui-fc.sensic.net" with a validity of 2 years.
App Cache stands for a technology that enables native apps to save data on your mobile device. While this is similar to the file cache, the data is retained in the app cache until the application or the user deletes it himself. For information on handling the App Cache, please refer to the help pages or the documentation for your mobile device.
SENSIC.net uses the app cache entries named "sui" and "sui_ac" with a validity of 2 years.
Mobile advertising ID: The mobile advertising ID is an online identifier for a mobile device that you can reset manually. It enables recurring devices to be recognized by mobile apps, usually for advertising purposes. For Android devices, the mobile advertising ID is called “Android Advertising ID”, for Apple devices it is called “ID for Advertiser (IDFA)”. The mobile advertising ID is associated with a device and can be accessed by apps that you use. For information on handling the mobile advertising ID, please refer to the help pages or the documentation for your mobile operating system.
Relay ID mechanism: The relay ID mechanism is a process that transfers the stored or temporary user ID to additional panel software or hardware. The mechanism therefore only works for users who have installed such panel software or hardware (e.g. DigitalTrends, Wakoopa Tracker, GfK Router, MyScan, GfK Influencers, Nicequest), i.e. only for participants in selected market research panels and other market research projects.

Potentially personal data, such as IP addresses and referrer URLs (Internet addresses of websites), are saved in anonymised form. We anonymize this data by shortening and hashing IP addresses and cutting off the entire part after the “top-level domain” from each referrer URL, for example everything after “.com” or “.de”.
Before we save IP addresses anonymously, we use them to determine in which country and in which region or city the respective usage process took place.

Within GfK: Your personal data can be passed on to one or more GfK companies if this is necessary for data processing and storage or in order to grant you access to our services, provide support, make decisions about service improvements or content development or for market and media research purposes. We do not disclose your personal data to third parties outside the GfK Group unless you have given your prior express consent for this specific purpose.
External serviceprovider: If necessary, we commission other companies and persons to carry out certain tasks that contribute to our services within the framework of order processing agreements. For example, we can pass on personal data to contractual partners or providers who manage our databases and applications for the purpose of providing data processing services. We only pass on such data to external service providers or allow them to access it to the extent necessary for the respective purpose. These data may not be used by the external service providers for other purposes, in particular not for their own purposes or the purposes of third parties. GfK's external service providers are contractually obliged to maintain the confidentiality of your personal data.
Business transfers: In connection with a start-up, reorganization, merger or sale or other transfer of assets (collectively "Business Transfers"), we transfer data, including personal data, to the extent that this is necessary for the business transfer, provided the receiving party agrees to yours treat personal data in a way that complies with applicable data protection laws. We continuously ensure the confidentiality of all personal data and inform affected persons - by timely notification on https://sensic.net/, or by contacting GfK market research participants directly - before personal data is subjected to another data protection declaration.
Public bodies: We only disclose your personal data to public bodies if this is required by law. For example, GfK responds to inquiries from courts, law enforcement authorities, regulators and other public and government agencies, which may include authorities outside your country of residence.
Under certain circumstances, it is also necessary for GfK to transfer your personal data to countries outside the European Union (EU) or the European Economic Area (EEA), so-called “third countries”. Such transfers to third countries can include all processing activities described in Section 3 of this data protection declaration. This data protection declaration also applies if we transfer personal data to third countries in which a different level of data protection prevails than in the country of your residence. In particular, international data transmission concerns the following scenarios:
Companies of the GfK Group: Internal data protection agreements exist with companies of the GfK Group outside the European Union based on standard contractual clauses issued by the European Commission to protect your privacy and to legitimize international data transfers.
Other third parties outside the European Union (EU) and the European Economic Area (EEA): Any transfer of personal data to third parties outside the GfK Group will only take place with your knowledge and, where applicable, with your prior consent. Any transfer of personal data to countries for which there is no adequacy decision with regard to the level of data protection from the European Commission, such as at https://ec.europa.eu/info/law/law-topic/data-protection/international-dimension -data-protection / adequacy-decisions_en, is made on the basis of contractual agreements that contain the standard contractual clauses issued by the European Commission or other guarantees that comply with applicable law.
GfK takes data security very seriously. We take all necessary physical, electronic and administrative security measures to protect the data, including personal data, that we collect from accidental or unlawful destruction, loss, alteration and unlawful disclosure, as well as unauthorized access to transferred, stored or otherwise processed personal data to prevent. Our guidelines and procedures for information security are based on generally recognized international standards and are regularly reviewed and updated as necessary to meet our business requirements, technological changes and regulatory requirements.
In the event of a breach of data security, which also affects personal data, GfK complies with all applicable laws regarding the obligation to notify in the event of a breach of the protection of personal data.
We reserve the right to change our data protection practices at our own discretion and to update and change this data protection declaration at any time. For this reason, we ask you to regularly check the data protection declaration available at https://sensic.net/ for changes. This data protection declaration applies from the date of the "last revision" mentioned above. We treat your personal data in accordance with the data protection declaration under which it was collected, unless we have your consent to other handling of your personal data.
