Privacy Policy

We, the Charité - Universitätsmedizin Berlin (PROVIDER; for further detail see Imprint) take the protection of your personal data very seriously and adhere strictly to the rules of the data protection laws. Personal data is collected on this website only to the extent technically necessary. In no case will the data collected be sold or otherwise disclosed to third parties. We also oblige all of our external service providers to comply with the same standards.

Please note that any form of data transmitted over the Internet (for example, when communicating via e-mail) may be vulnerable to interception. For technical reasons, a complete protection of the data from access by unauthorized third parties is generally not possible. We make every effort to protect your data in the best possible way. Learn more, how to protect your personal data here.

The following statement explains how we warrant the protection of your data and what kind of data we collected and for what purposes.

Personal Data

Personal data is every kind of information that can be linked to the personal and material circumstances of a specific or identifiable natural person. This includes information such as your name, home address, postal address, telephone number. Information that is not linked to your identity (such as the number of people using this website) is not included. Under rare circumstances a very unique combination of not personally identifiable information can be linked to your identity. Please be aware of that when providing non personally identifiable information!

Generally, you can use our online service without revealing your identity.

Information Processing on this Website

The PROVIDER does not save Server Log Files, i.e., information sent from your browser. When using the program, anonymized data is generated and collected. This data is used for the technical functionality of the program, the self-test feedback function of the program, the utilizatiion and scientific evaluation of the chat-study, quality control, the dissemination of the program (online/offline), statistical evaluation and scientific research. No personally identifiable data is collected for this purpose.

For the content management of Troubled Desire, we use the Web-CMS TYPO3. The following page types are used: Home Page, simple page with text, image, video and audio content and an online survey (self-test), survey form for user feedback, chat and message function in the login-protected area.

If the user starts a new session, self-test or chat-application it is stored under a randomly generated cryptic ID. This ID is displayed to the user at any time while browsing the login-protected area. Only through this ID the user can gain access to the entered data again. For each cryptic ID, in addition to the answers given to the questions in the online surveys, the messages and chat-logs in the chat-study, the following data is stored: progress of the online survey, date and time of first access to the online survey and date and time of last change and last access to the online survey.

Please be aware that your answers in the online sessions might contain personally identifiable information. Depending on the information you provide (especially for open-ended question), and in the chat- and message windows when participating in the chat-study, your answers may suffice to make you personally identifiable. You can prevent that by omitting any names, dates, facts or any other unambiguously personal details in your written responses. You do not need to provide any personally identifiable information to take part in the self-test, surveys or chat-study. Your omission of any personally identifiable information has no influence on the quality of your user expierience.

Legal basis for the processing of information

The legal basis for the processing of information (for example IP addresses) is Article 6, § 1, P.1 lit. f. GDPR. This applies when the website is used for purely informative reasons and without using the online sessions, self-test, surveys or participating in the chat-study. Article 6, § 1, P.1 lit. b. GDPR applies when the online sessions, self-test, surveys or the chat-study is used, i.e. questions are being answered or own information is shared.

The legal basis for the processing of the survey data (online sessions, self-test, surveys, chat-study) are Article 9, § 2, lit. h. GDPR in conjunction with Article 6, § 1, lit. b. GDPR, § 22 Section 1 No. 1 lit. b BDSG for the technical functionality of the program, for example the content feedback function, and Article 6, § 1, lit. f. GDPR respectively § 27 Section 1 BDSG for the statistical/scientific evaluation of data shared in the online-sessions, surveys and message- and chat-windows when participating in the chat-study.

The legal basis for the determination of country/region of access through the means of GeoIP are Article 6, § 1, lit. f. GDPR and § 27 Section 1 No. 1 BDSG for the statistical/scientific evaluation of the collected data, for example as a way to determine the regional demand for treatment, the efficacy and quality of the services.

The valid interest of the PROVIDER to collect data is listed above as purpose for information processing. Never will the PROVIDER use collected data for the purpose of drawing conclusions to your person. For the PROVIDER, there is no way to connect the data to any particular user or natural person.
