MDPI Privacy Policy

We have aligned this Privacy Policy with both the Swiss Data Protection Act (“SDPA”) and the EU General Data Protection Regulation (“GDPR”). The GDPR has established itself worldwide as a benchmark for strong data protection, therefore our company has set itself to implement the highest standards in data protection. As GDPR and SDPA may have slight differences in the definitions used, we base the following Privacy Policy text on GDPR definitions, which have the same meaning in SDPA. Notwithstanding the above, please note that whether and to what extent the GDPR or SDPA is applicable to you depends on the individual case.

The protection of your personal data is important to us, especially with regard to safeguarding your personal rights when processing and using this information. When you use this website, various personal data are processed depending on the type and scope of use.

The storage of server log files is necessary for technical reasons to provide a functional website and to ensure system security.

In addition to the above-mentioned purposes, we use server log files solely for the purpose of designing and optimizing our website in line with demand, purely for statistical purposes and without any reference to your person. A personal evaluation of the server log files does not take place. This data is not merged with other data sources. The access data collected in connection with the use of our website is only stored for the period of time for which this data is required to achieve the aforementioned purposes. Your IP address is stored on our web server for a maximum of two years for IT security purposes. For data stored through cookies, please see section 3 below.

In addition, Art. 6 para. 1 sentence 1 lit. f GDPR serves as the legal basis for the temporary storage of technical access data. Our legitimate interest in this regard is to be able to provide you with a technically functioning and user-friendly website and to ensure the security of our systems.

To make use of personalized services, you will have to register a user account with our websites. During registration we will ask you to provide some personal information, including, but not limited to, your name, valid e-mail address, affiliation, postal address, phone number, password, academic degree, position within your institution or organisation, and your research interests.

With your consent, you can subscribe to the newsletters we offer as part of our services (e.g. regarding journals or other offerings).

For the subscription to our newsletters, we use the so-called double-opt-in procedure. This means that after your registration, we will send you an e-mail to the e-mail address you provided, in which we ask you to confirm that you wish to receive the newsletter. In addition, we store your respective IP addresses used and times of registration and confirmation. The purpose of this procedure is to be able to prove your registration and, if necessary, to clarify a possible misuse of your personal data. Only your e-mail address is required for sending the newsletter. The provision of further, separately marked data is voluntary and will be used to address you personally. After your confirmation, we store the data you have provided for the purpose of sending you the newsletter (legal basis is Art. 6 para. 1 lit. a GDPR).

You can withdraw your consent to the sending of the newsletter at any time and unsubscribe from the newsletter. You can declare the withdrawal by clicking on the link provided in every newsletter email.

We pass on at least some of your data that we collect in accordance with the aforementioned paragraphs to processors. These process your data only on our instructions and not for their own purposes (Art. 28, 19, GDPR). These are companies that can be assigned to the following categories:

- Third party online databases, or platforms or indexing & abstracting services to share article data as published on


If we transfer data to recipients in a third country (located outside the European Economic Area, “EEA”), you will learn about this from the information on the recipients/categories of recipients and the underlying legal basis in accordance with Article 46 (2) of the Data Protection Regulation as part of the description of the respective data processing. Some third countries are certified by the European Commission through so-called adequacy decisions as having a data protection standard that is comparable to the level in the European Economic Area. You can find a list of these countries at If a country does not have a comparable data protection standard, we ensure that data protection is sufficiently guaranteed by other measures. This is possible, for example, through binding corporate rules, standard contractual clauses of the European Commission for the protection of personal data, certificates or recognised codes of conduct. Otherwise, we do not transfer your personal data to countries outside the EU or the EEA or to international organisations, unless expressly stated otherwise in this privacy policy.
