Privacy Policy

Helmholtz-Zentrum Dresden-Rossendorf e. V. (HZDR) takes the protection of personal data seriously.

The following privacy policy provides you with information on what personal data we (the controller as defined in the General Data Protection Regulation) collect when you visit our website and/or use our online services as well as how we utilize your data. Personal data includes all data with which you can be personally identified. The website is hosted on an internal HZDR server.

Protocols, Log Files

When users access our website, data such as the computer’s IP address, internet browser used, date, and time are automatically logged for technical reasons and saved for a period of seven days in our system log files. Saving in log files occurs to ensure the functionality of the website and the security of our information technology systems. This data is therefore only evaluated when technical problems or attacks on our webserver arise. The legal basis for data storage is Article 6, Paragraph 1 f GDPR (legitimate interest). Combining this information with other user data does not occur.

We do not use analysis tools.

Contact Forms, Registration Forms and Online Applications

Furthermore, we in no way save or gather personal data through this website (such as names, addresses, telephone numbers or email addresses) unless you provide us with such information (e.g., if you get in contact with us, utilize registration forms for events and workshops or fill in online applications) and in the context outlined as follows. Personal data you willingly provide (also in regard to required fields as part of your request) is treated confidentially, serving only to process your request, and will not be passed on to third parties without your consent and/or your being informed in regard to that particular form. The data is processed and stored on the basis of a legitimate interest (Art. 6, Par. 1 f GDPR, or in the case of requests for offers pursuant to Art. 6 Par. 1 b GDPR) in processing your respective request.   

Please also be aware of our specific privacy policy information on the respective forms.

All personal data is deleted or blocked as soon as the purpose of the storage no longer applies. Furthermore, storage may also take place to the extent it is permitted by European or national legislation.

We use SSL encryption so that the data you enter on our homepage is transferred to us in encrypted form. Users should, however, be aware that Internet data transfer (e.g., through email communication) can encounter security issues. Complete protection from access by third parties is impossible.

Log-in Area

The log-in area is in principle available only to our staff. Staff will be informed separately insofar as data processing beyond the scope of this privacy policy takes place within the log-in area.
