An personal data collector implemented to study relationships.
This data collector is built on top of the PrivacyStreams library. All personal data related operations are made possible through simple PrivacyStreams API calls.
As a developer/researcher, you need to set up your dropbox developer account to get a Dropbox access token to upload your collected data to a remote dropbox. For details, please refer to the Dropbox official tutorial. In order not to commit the key on github, once you got the key, create a file locally called secrets.xml and put the access token in the file under the folder res/values.
