(3) Legal basis of the processing

Your data is primarily processed under the provisions of the General Data Protection Regulation of the European Union (“GDPR”).

(4) Types and purposes of data processing

The Solomiya app is programmed to process as little personal data as possible. There are no user accounts stored on the server system. In particular, your data will not be used for profiling or advertising purposes.

The data processed by the app can be classified into the following categories:

  1. Access data

Each time the Solomiya app exchanges data via the internet with the server system of the Charité (hereinafter: server system), the server system processes so-called access data. This is necessary so that the app can retrieve current data or transmit certain data stored on the smartphone to the server system. The access data include the following data:

  • IP address
  • Date and time of the retrieval
  • Amount of data transferred (or packet length)
  • Message as to whether the data exchange was successful

The legal basis for the temporary storage of the personal data and the log files is Art. 6 Sect. 1 lit. f GDPR for the protection of the legitimate interests of Charité. The above-mentioned access data is processed in order to maintain and secure the technical operation of the app and the server system. You will not be personally identified as an app user and no usage profile will be created. The IP address is not stored beyond the end of the app usage.

  1. Usage data

We use the data protection-friendly open source tool “Matomo” for the analytical evaluation of usage data. This analysis tool is used on the basis of Art. 6 Sect. 1 lit. f GDPR. Matomo enables us to collect and analyze data about the use of the Solomiya app. This allows us to track, e.g., which screens and videos were viewed within the app (by storing a video ID) as well as the average time spent per screen/video. The purpose of these data analyses is to optimize the content and functionalities of the Solomiya app. 

Matomo does not transmit data to servers that are outside the control of the Charité. We host Matomo exclusively on the Charité server system. Data about your usage behaviour (tracking) is processed anonymously by Charité and is generally only collected if you have given your explicit consent to do so. Consent can be revoked at any time.

  1. Health data

Health data is any data that contains information about a person’s health status. As part of a monitoring feature (self-assessment), the Solomiya app collects your answers within specific questionnaires (Patient Health Questionnaire (PHQ-9) and Insomnia Severity Index (ISI)) to assess the severity of depressive symptoms and insomnia. These responses are processed anonymously, stored only locally on your device, and cannot be associated with IP addresses or user profiles at any time.

Moreover, users can enter and save emergency contacts in the Solomiya app – including names, descriptions, contact images and telephone numbers of the relevant contact persons. This data is not sent to the server system, but is stored locally on the user’s device.

(5) Recipients of the above data
As the technical service provider commissioned with the development of the Solomiya app, Bornholdt Lee GmbH are granted access to the Charité server and the above-mentioned data which remain anonymized at all times and are not processed by Bornholdt Lee GmbH.

(6) Duration of storage
As soon as the Solomiya app is uninstalled, your data that was stored locally on your device for the duration of use (e.g. questionnaire answers, emergency contacts) will also be permanently deleted. The log files – including your IP address – are deleted from the server system after fourteen days. Only usage data which was collected through Matomo and cannot be traced back to individual users is not automatically deleted.

(7) Data subject’s rights regarding personal data
