You can donate the physiological and behavioral data and help us to develop a system for better health of all of us. A bit details about the project can be found on our lab's (Sensing System for Health, University of Virginia) website (https://s2helab.com/context-aware-micro-interventions-for-social-anxiety/).

Data Collection
After installation of the app, once you give the required permissions, Mindtrails Watch will collect the following data.

Acceleration
Ambient light
Battery power
Features of audio
Gravity
Heart rate
Location [currently, though we take permission to access the location, we are neither retrieving nor storing the location. However, in the near future version, we will retrieve and store this data if you give permission.]
Magnetometer
Photoplethysmography
Step count
Watch put off and put on time

Data Privacy, Safety and Ethics

We do not store the raw audio. Instead, we process the audio inside the app and keep only the features that we encrypt before storing it on a server. Moreover, we store the features only as binary values which are not human readable. Besides, the raw audio file (which we temporarily keep inside the app just to extract features) is deleted as soon as the feature extraction is complete which can be completed within certain minutes.

The files containing your data that will be kept inside the app temporarily (until you upload the data by connecting to the internet) can not be accessed by any other apps of the Watch.

We do not collect continuously and also do not collect data at night (12 AM to 8 AM). We collect data once (for 1 minute) every 5 minutes only if you keep wearing the watch. You can put off the watch anytime you want (e.g., during any private conversation when you do not want to provide data).

We will not collect data on the corresponding sensor if you do not give permission during installation or you revoke the permissions (e.g., microphone for audio) afterward. You can change the given permission anytime.

Your data is going to be stored in secure storage that can be accessed by only the researchers (who are in the IRB approved by the University of Virginia) of our project.

We do not collect personally identifiable information such as name, phone number, email address, etc.
