Datarella is a big data collection company based in Germany. Their "Explore" app accesses sensors in smartphones and wearable devices to record data like location, environment, and personal behavior. This data is then aggregated and issued in a way that respects user privacy to Datarella partners to help increase their customer data portfolio. The Datarella API provides a way that users may access these data sets to consume real time analytics from Explore app users. In addition to OAuth, the API accepts a user's Explore App login email and password for authentication.
