Data protection information

The Max-Planck-Gesellschaft zur Förderung der Wissenschaften e.V. (MPG) takes the protection of your personal data very seriously. We process personal data gathered when visiting our websites in compliance with the applicable data protection legislation and, as a matter of principle, only to the extent that this is necessary to provide a functioning website and our content and services. We neither publish your data nor transmit them to third parties on an unauthorized basis.

In the following sections, we explain which data we record when you visit one of our websites, and how exactly they are utilized.

A.    Provision of the website

           a. Type of data

Each time you visit our website, our service and applications automatically record data and information from the computer system of the visiting computer.

The following data are gathered temporarily:

  • Your IP address
  • Date and time of your access to the website
  • Address of the page visited
  • Address of the previously visited website (referrer)
  • Name and version of your browser/operating system (if transmitted)

These data are stored in our systems' log files. There is no storage of these data together with other personal data relating to the users.

  1. Legal basis

The legal basis for the temporary saving of data and log files is Article 6 (1) lit. f GDPR. Storage occurs in log files in order to ensure the website's functionality. The data also serve to optimize the websites, eliminate malfunctions and ensure our IT system security. Our justified interest in data processing pursuant to Article 6 (1) lit. f GDPR also lies in such purposes.

The recording of data for the provision of the website and the storage of data in log files are essential to operate the website. It is therefore not possible for the users to object.

  1. Data deletion

The data are deleted as soon as they are no longer required in order to fulfil the purpose of their collection. If data are gathered for the provision of the website, this is the case if the respective visit is ended. In the event that data are stored in log files, this is the case after seven days at the latest. Storage above and beyond this period is possible. In this case, the users' IP addresses are deleted or removed so they can no longer be allocated to the visiting client.

B.   Web analysis

The following data are collected additionally if JavaScript is activated:

  • URLs visited on this website
  • Times of page visits
  • Type of HTML requests
  • Screen resolution and colour depth

The saving and analysis of data is carried out solely on a central server operated by the MPG. In addition to the central website, it is also used by most Max Planck Institutes and many MPG project websites.

It goes without saying that you have the opportunity to object to your data being collected. The following independent methods are available to you if you wish to object to data collection by the central server:

  1. In your browser, activate the Do-Not-Track setting. As long as this setting is active, our central server will not save any of your data. Important: Do-Not-Track generally only applies to the one device and browser on which the setting is activated. If you use several devices/browsers, you must activate Do-Not-Track separately on each one.
  2. Use our opt-out function. Click on the check mark in the following selection box under in order to stop or reactivate data collection. As long as the selection box is deactivated, our central server will not save any of your data. Important: For the opt-out, we have to store a special recognition cookie in your browser. If you delete this or use a different PC/browser, you have to object to data collection once again on this page.

There is no storage of these data together with other personal data relating to the user.

  1. Legal basis

The legal basis for the processing of personal data by means of cookies is Art. 6 (1) lit. f GDPR as well as § 25, para. 2, no. 2 TTDSG. The processing of the users' personal data enables us to analyze the usage behaviour of our users. By evaluating the data obtained, we are able to compile information on the use of the individual components of our websites. This helps us improve our websites and their user-friendliness on an ongoing basis. These purposes also constitute our legitimate interest in data processing according to Art. 6 (1) lit. f GDPR as well as § 25, para. 2, no. 2 TTDSG. By anonymizing the IP address, the users' interest in the protection of their personal data is sufficiently taken into account.

  1. Data deletion

The data are deleted after the final annual totals have been arrived at for access statistics.

C.    Push Notifications

  1. Type of data

On our website, it is possible to activate push notifications for the browser. For this purpose, the login time and a push token or device ID are stored. On the one hand, these data serve to be able to send you the push notifications and, on the other hand, as proof of your registration. As part of the activation process, we obtain your consent and refer you to this Data Privacy Statement. The data are solely used for sending out the push notifications. Tracking or the collection of statistics is not performed.

The subscription can be activated via the bell symbol next to the search field by placing a check mark in the selection field. For this to function, receiving notifications must be activated in the browser. The notifications are limited to the browser used when activating the push notifications; for use in further browsers, the push notifications must be activated separately. Notifications are only delivered when the browser is open.

  1. Legal basis

The legal basis for processing the data after a user signs up for push news is the user's consent according to Art. 6 (1) lit. a GDPR. The purpose of data collection is to be able to send out the push news.

  1. Data deletion

The user's token is therefore only saved for as long as the subscription to the push news is active. The subscription to the push news can be cancelled by the user in question at any time.

In the same way as activation, deactivation is carried out via the bell. Removing the check mark from the selection box deactivates the subscription.


D.    Data transmission
