The company, Anomaly Six LLC, draws location data from over 500 apps - partly through their proprietary software development kit (SDK) which they've paid to embed directly in some of the apps, while the company gets location data from partner providers. The SDK allows the company to obtain a user's location if they have allowed the apps in question to access the phone's GPS coordinates. - Zero Hedge
Anomaly Six said it would support regulation to require more disclosure by apps of how data is collected and used. The exact apps the company partners with couldn’t be determined and the company declined to comment, citing confidentiality agreements. The partnerships between data brokers and app makers are typically closely held trade secrets within the world of commercial-data sales. -WSJ
