GENERAL INFORMATION ON DATA PROCESSING

We process our users’ personal data only insofar as is necessary to provide a functioning website as well as our content and services. If individual websites or functions implement processes departing from this privacy statement, information regarding this will be provided in a separate privacy statement.

Institut für Technische Chemie

PROVISION OF THE WEBSITE AND CREATION OF LOG FILES

Every time you visit our website, our system automatically collects data and information from the computer system of the accessing computer.

The following data is collected:

Information about the browser type and version used

  • the user’s operating system
  • the user’s internet service provider
  • the IP address of the user
  • the date and time of access
  • the website, from which the user’s system reaches our website
  • websites accessed by the user’s system via our website


The data is also stored in the log files of our system. This data is not stored together with other personal data of the user. The legal basis for temporary storage of data and log files is Article 6 (1) (e) and Article (3) GDPR in conjunction with section 3 of the Lower Saxony Data Protection Act (NDSG) and section 3 of the Lower Saxony Higher Education Act (NHG).

Temporary storage of the IP address by the system is necessary to enable the website to be delivered to the user’s computer. For this, the IP address of the user must remain stored for the duration of the session. The data is stored in the log files to ensure the functionality of the website. In addition, the data enables us to optimize the website and to ensure the security of our IT systems. Analysis of the data for marketing purposes does not take place in this context.

The data will be deleted as soon as it is no longer necessary to achieve the purpose for which it was collected. With respect to collection of data for the provision of the website, this is the case once the respective session has ended.

If the data is stored in log files, this is the case after seven days at the latest. Data may be stored for a longer period of time. In this case, the IP address of the user is deleted or anonymised, so that the accessing client can no longer be assigned to the user.

For technical reasons, collection of data for the provision of the website and storage of data in log files is essential for the operation of the website.

CONTACT FORM AND EMAIL CONTACT

There is a contact form on our website that can be used for electronic contact. If a user utilizes this function, the data entered in the form will be transmitted to us and stored. In this context, the data will not be passed on to third parties. The data will be used exclusively for processing the conversation. The legal basis for processing data is Article 6 (1) (a) GDPR provided that the user has given consent. The legal basis for processing data transmitted in the course of sending an email is Article 6 (1) (e) and Article (3) GDPR in conjunction with section 3 of the Lower Saxony Data Protection Act (NDSG) and section 3 of the Lower Saxony Higher Education Act (NHG). If email contact is undertaken with the purpose of concluding a contract, the additional legal basis for processing is Article 6 (1) (b) GDPR.

Personal data that is entered in the input mask is processed solely for the purpose of establishing contact. The other personal data that is processed during the sending process serves to prevent misuse of the contact form and to ensure the security of our IT systems.

The data will be deleted as soon as it is no longer necessary to achieve the purpose for which it was collected. For personal data that was entered in the input mask of the contact form or sent via email, this is the case when the respective conversation with the user is finished, unless statutory retention periods apply that would prevent erasure. The conversation is terminated when it can be deduced from the circumstances that the facts in question have been conclusively clarified.

The user can revoke consent to the processing of personal data at any time. If the user contacts us by email, he or she can object to the storage of personal data at any time. In such a case, the conversation will be terminated and all personal data collected during the conversation will be erased unless statutory retention periods apply that would prevent erasure.

FORM ENTRIES

Where internet services allow personal or business data (e.g. email addresses, names, addresses) to be entered, disclosure of such data by the user shall take place on an explicitly voluntary basis. Unless indicated or unless information on a separate privacy statement is provided, the legal basis for such processing is Article 6 (1) (a) GDPR. The collection and processing of data serves only the purpose stated in the respective online form. Unless indicated, divulgence or disclosure to third parties shall not occur.

WEBSITE STATISTICS

We compile anonymous statistics and analysis of access to our websites. The open-source software tool Matomo (formerly PIWIK) is used to compile anonymous website statistics. Thus, no personal data is processed. The use of cookies is deactivated in the Matomo web analytics software. The last two octets are not processed upon storing the IP address of the user. The function to collect the user ID is deactivated. In addition to data regarding access to our website and your anonymised IP address, the following data is collected: The date and time of the request, page accessed, URL of the previously accessed page (referrer URL), screen resolution of the client’s system, local time zone, URL of clicked and downloaded files, URL of clicked external domains, geolocation of the client (country, region, city), main language used by the browser, user agent of the browser used.
