The Electronic Privacy Information Center has filed a complaint with the Federal Trade Commission over Uber's plan to track user data.
The ride-sharing company said the plan calls for tracking users even if their app is closed and the GPS is turned off.
"I am not a fan of that," said Dale Curtis, who uses the Uber service in San Francisco. "Keep the policy they have right now and I'll keep using them."
The Electronic Privacy Information Center's complaint said Uber's policy far exceeds what customers expect from the company.
Uber on Monday issued the following statement in response:
"There is no basis for this complaint. Our new privacy statements are much simpler to read and set out more clearly the data we collect, as well as how we use it."
Uber also said users can always opt out. The policy change is expected to go into effect in three weeks.
