The Electronic Privacy Information Center, or EPIC, says it is concerned about Uber’s privacy. The group says the app’s ability to track a user’s location – even when the app is closed – is a big concern. Uber says users will be in control of what data is shared with the company. Uber is a location-based app; the GPS signal in your phone is what tells a driver where to pick you up. EPIC is asking the FTC to stop Uber from rolling out its new policy and investigate the company for compliance with various privacy laws.
