SHEBOYGAN, Wis. (CBS 58) -- Sheboygan's Common Council is deciding whether to end the city's partnership with Flock and its automated license plate readers. 

Sheboygan was among the first communities in recent weeks to raise concerns that Flock was retaining and selling data the city was not aware of. Recently, city crews put plastic bags over the cameras to prevent them from gathering data on drivers. 

Mayor Ryan Sorenson told us Flock cameras have helped solve crimes, but the company selling the data is a violation of trust. Sorenson says that hurts Sheboygan's goal of focusing on community policing. 

"When we have a tool and a vendor that violates that trust fundamentally, and how it's being used and how they're maintaining and distributing data, that erodes our ability to be an effective police department," Mayor Sorenson said. 

Flock Safety did not directly address our questions about Sheboygan's concerns, but a spokesperson pointed us to a section of Flock's website that describes its traffic analytics feature. Flock says that tool "is a separate product from our LPR (license plate reader) platform."

The Flock website says:

"Traffic Analytics turns roadway observations into aggregate trends, without retaining license plate data or individual vehicle information in the analytics product. It uses Flock's existing camera infrastructure to produce traffic measurements that agencies can view in a dashboard or export for further analysis."
