3. General information on data processing

We collect and use the personal data of our users insofar as necessary for operating a functional website and delivering our content and services, and to the extent to which the law permits.

3.1. Legal basis for processing personal data

Whenever we obtain the consent from a data subject to process personal data, Art. 6 (1 a) GDPR serves as the legal basis for processing this personal data.

Whenever processing such data is necessary for compliance with a legal regulation, to which the Friedrich-Alexander University Erlangen-Nürnberg is subject, Art. 6 (1 c) GDPR serves as the legal basis.

In cases for which processing is necessary to protect the vital interests of the data subject or of another natural person, Art. 6 (1 d) GDPR serves as the legal basis.

If processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the Friedrich-Alexander University Erlangen-Nürnberg, Art. 6 (1 e) GDPR serves as the legal basis for processing this data.

If processing is necessary for safeguarding the legitimate interests of the Friedrich-Alexander University Erlangen-Nürnberg or of a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject, Art. 6 (1 f) GDPR serves as the legal basis for processing this data. This does not apply to processing tasks which the Friedrich-Alexander University Erlangen-Nürnberg is obliged to perform as a public authority.

3.2. Duration of storage of personal data

We reserve the right to retain the data subject’s personal data for as long as the purpose of such storage exists. If processing is permitted on the basis of the subject’s consent, his/her personal data is only stored until the data subject withdraws his/her consent, except in cases where processing is governed by a different legal basis.

3.3. Right to rectification and erasure of personal data

The data subject has the right to obtain from the controller without undue delay the rectification of inaccurate personal data concerning him or her. The data subject also has the right to obtain from the controller the erasure of personal data concerning him or her without undue delay as soon as the purpose of storage is no longer necessary. In cases where data processing is performed on the basis of consent, the right to erasure exists if the data subject withdraws his/her consent and no other legal grounds exist for processing the data.

Personal data must be erased if the data subject objects to the processing in accordance with Art. 21 (1) GDPR and there are no overriding legitimate grounds for the processing, or if the personal data has been unlawfully processed, or if the personal data must be erased in order to comply with a legal requirement mandated by an EU or member state law, to which the Friedrich-Alexander University Erlangen-Nürnberg is subject.

The right to erasure as put forth in the cases stated above does not apply, however, if it would prevent compliance with a legal obligation which requires processing by European Union or member state law, to which the Friedrich-Alexander University Erlangen-Nürnberg is subject, or hinder the performance of a task carried out in the public interest or in the exercise of official authority vested in the Friedrich-Alexander University Erlangen-Nürnberg, or if extended storage is necessary for the establishment, exercise or defence of legal claims.

3.4. Right to withdrawal

If permission to process personal data was granted by the consent of the data subject, he or she may withdraw his/her consent at any time. All processing of personal data performed prior to withdrawal remains lawful irrespective of the subject’s withdrawal.

3.5. Right to information

The data subject has the right to obtain confirmation from the Friedrich-Alexander University Erlangen-Nürnberg whether it is processing any personal data concerning him or her. If such is the case, the data subject has a right to information regarding the type of personal data and the purpose for which it is being processed. The data subject also has the right to obtain information on the duration of the planned storage of his/her data, or on the criteria for determining how long his/her data is to be stored.

This data is compiled in log files and saved on our server. No further personal data is stored together with the log file data.

4.2. Legal basis for processing

The legal basis for temporarily processing data and log files is provided in Art. 6 (1 f) GDPR.

All log files will be deleted after the data acquisition phase of our online study ends.

The study participation can be cancelled by the user at any time. For this purpose, a cancellation link is embedded in each of the weekly emails. When cancelling the study participation by visiting such a link, the email address of the user will be deleted from the database immediately.

7. Study Participation: Browser Fingerprints

7.1. Scope of data processing

Browser fingerprints are digital fingerprints of browsers and consist of various characteristics that can be accessed either via obligatory HTTP communication or by executing code via client-side scripting languages, such as JavaScript.

For this purpose, we send weekly emails to our participants with personalized links to a subpage of our website, where the fingerprints of participants' are collected.

During registration, participants can freely choose whether they agree that their browser fingerprints may be published in an anonymous form for research purposes. If not, the use of their data is limited to the study team.

We use Shariff, a solution by German computer magazine c't and heise online that provides privacy for visitors that neither want to make use of these buttons, nor their browsing data to be leaked to social networks. There will be no connection and no data exchange with servers of social networks, unless you explicitly click on one of the buttons (except email, it only opens your local email client).

Those who want to make use of these buttons will transmit data (e.g., IP address, referrer URL) to Web servers of the respective social network by clicking on the corresponding buttons. Furthermore, your social media account provider will be able to analyze your browsing behavior and link it with your user ID and also with further data if you decide to use social media buttons (in general).

In the following, you can see every company for which we provide a social media button as well as a link to their terms of service and privacy policy:
