Different self-reported questions will be answered via external surveys. While performing the breathing training, the device’s microphone will capture voice commands and breathing sounds. All data will be screened before further processing happens and sounds other than your voice command or breathing will be irreversibly removed (e.g., any conversations or other sounds that may allow your identification). During the breathing training, additional sensors may also collect data, if accessible, such as the device’s accelerometer, gyroscope, magnetometer, light sensor, ambient temperature sensor, humidity sensor, pressure sensor, and step counter (only steps since the app was started). The app also records reaction time to the chatbot. The data obtained will be stored safely on General Data Protection Regulation (GDPR)-compliant servers. They will be reported in an anonymous form only, for example, as part of scientific publications. Only the responsible investigators or the members of the Ethics Commission will have access to the original data under strictly observed rules of confidentiality.
