To aid in recovering responsive documents, please see the following news article mentioning the City's use of BlueDot products/services: (archived version - )

An excerpt from the article reads: "..the new data released by the city is the use of mobile devices to track and determine that Chicagoans are, for the most part, adhering to the stay-at-home order. Lightfoot and Arwady said the information was provided by the risk software company BlueDot through the data collection company SafeGraph. They characterized it as “anonymous” data gathered from users of mobile device applications who agreed to let certain applications track their locations.

“We don’t know, nor would we get, specific information about cell phone users,” Lightfoot explained. “So I don’t think there’s any privacy issues. And it’s dependent upon one’s use of applications and then allowing access related to location.”

Arwady said potentially “hundreds of thousands” of mobile devices were tracked as part of the study. A check-in occurred on each of those phones every half-hour, she explained. The study assumed the device’s most common location between midnight and 9 a.m. was its “home.”"

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 5 business days, as the statute requires.
