According to Art. 4 No. 1 of the General Data Protection Regulation (GDPR), personal data is all information relating to an identified or identifiable natural person.

3) Storage location for data, especially personal data

All data is stored on an encrypted server of the University Hospital Würzburg.

The data exchange between your mobile device and the server takes place via the Internet, based on a secure SSL connection.

A transfer of personal data to a third country or to international companies or organizations is precluded.

4) Authorizations of the app

No authorizations are required to use the app with full functionality.

If you give the app permission for the location data (Android and iOS mobile operating systems) or app usage data (only Android mobile operating system), we can use this data for scientific analysis. However, this is not necessary to use the app to its full extent.

5) Use of location data

If you grant the authorization, the GPS data of your smartphone will be stored, in particular to enable scientific analyses. However, you can also use the app without granting authorization for GPS data.

Other location data will not be retrieved, processed or stored. In particular, no geotracking is performed by our app. Importantly, location data will be scientifically processed only in a coarse-grained way (resolution 11,1 kilometres).

6) Use of app usage data

If you grant the authorization, the following app usage data sources of your smartphone will be stored, in particular to enable scientific analyses. However, you can also use the app without granting authorization app usage data:

(1.) usage frequency and duration of the fifth most used apps

(2.) usage frequency and duration of the following communication apps (if installed): phone, SMS, WhatsApp, Facebook, Facebook Messenger, Telegram, Skype, Snapchat, Zoom, Instagram.

Other app usage or communication data will not be retrieved, processed or stored and no content of your communication will be transmitted

7) Use of push services

The app uses push services of the operating system manufacturers. These are short messages that are displayed on the user’s screen with the user’s consent and actively inform the user about recently available questionnaires or news.

If the push services are used, a device token from Apple or a registration ID from Google may be allocated. The sole purpose of their use by us is to provide the Push Services. These are only encrypted, anonymised Device IDs. We cannot draw any conclusions about the individual user.

You can decide during the installation of the app whether you want to use this functionality. If you want to unsubscribe from the push messages later, you can use the unsubscribe option in the app. You can find this under the settings.

8) Evaluation of usage data

The device recognition of your smartphone is saved. This is necessary to be able to correctly assign your data to the app if you use it several times. This allows the user to find out, for example, the frequency of use and previous results.

Anonymized usage data, e.g. answers to health questionnaires, are processed for the secure operation of the app and, if necessary, evaluated for its further development. However, it is not possible to make connections of this data to your person. This anonymous usage data is also not merged with other data sources.

When using the app, this data is stored in a log file with a timestamp.

9) Research purpose and scientific publications

The results of the anonymous app use can be published in scientific journals within the scope of research projects. However, it will in no way be possible to identify your personal identity on the basis of your personal data collected and processed by the app.

10) Transfer of data to third parties

Data that has been logged during the use of the app and will be used by the participating scientists and collaborating partners for scientific purposes only. Exceptions to this rule can only be made if this is required by law, a court decision or if the transfer is necessary for legal or criminal prosecution. A transfer for commercial purposes will not take place.

The app contains links to websites or applications of other providers. Compliance with data protection regulations on these external locations is the responsibility of the respective operators, so that we cannot assume any guarantee or liability. We therefore ask you to contact this provider to find out about their data protection practices and their corresponding legally binding data protection declaration.
