The new policy, set to take effect on July 15, would give the ride-hailing service access to users' address books and allow the company to collect location data even when the app is running in the background.
Those changes, the Electronic Information Privacy Center wrote in a complaint filed to the Federal Trade Commission Monday, "threaten the privacy rights and personal safety of American consumers … and constitute an unfair and deceptive trade practice."
But in its complaint, EPIC argues that the policy places an "unreasonable burden on consumers" and that it is "not easy to exercise" the ability to opt out of the data collection.
Monday's complaint from EPIC doesn't necessarily mean that the FTC will take any action against Uber. The agency only has authority to pursue cases against companies if their practices are "unfair" or "deceptive."
"We welcome complaints from consumers and consumer groups and review them carefully," said FTC spokesman Jay Mayfield.
