Data Privacy Statement

1. Data Storage and Use

The email address you enter in the context of a check is used by the Hasso Plattner Institute for Digital Engineering gGmbH for data reconciliation and sending the reply email.

The entered email address and the client IP address are temporarily stored by us in a database in a concealed form (hash) in order to detect automated requests.

2. Right of access, deletion and data blocking

(1) Because the source of the Identity Leak Checker’s data set does not allow specific assignment to an individual (§4 Abs. 1 DSGVO), we cannot provide any information about the data set according to §15 DSGVO. We do make it possible for the owner of an email address contained in our data set to block or delete this address as an information source (database queries and sending email).

(2) For further questions that do not pertain to paragraph 1, please contact the data protection officer at Hasso Plattner Institute. To do this, submit your request in writing to:

Hasso-Plattner-Institut für Digital Engineering gGmbH
Data Protection Officer
Prof.-Dr.-Helmert-Str. 2-3
D-14482 Potsdam

or alternatively by email to: datenschutz(at)

3. Server Log Files

The page provider collects and stores information in so-called server log files, which your browser automatically transmits to us. The following information is transferred:

  • Name of the accessed file
  • Date and time of access
  • Volume of data transferred
  • Notification as to whether file retrieval was successful
  • IP address
  • Web address previously accessed (Referrer URL)
  • Information about the operating system
  • Browser
  • Host name

This data cannot be associated with specific individuals. A combination of this data with other data sources is not carried out. We reserve the right to retroactively check this data if we become aware of warranted indications of unlawful use.

4. Links to Other Websites

Our website contains links to the websites of other, unrelated providers. After clicking on such a link, we no longer have any influence on the processing of any data that is transferred to the third party (such as the IP address or the URL on which the link is located), since the behavior of third parties is beyond our control. Therefore, we cannot accept any responsibility for the processing of any such data by third parties.
