Arizona Covid Watch data

To Whom It May Concern:

Pursuant to the Arizona Public Records Law, I hereby request the following records:

1) Data documenting the number of times the Arizona Covid Watch COVID-19 exposure app was downloaded from the date the app was launched until the present. The department has publicly disclosed the existence of his data to multiple media outlets and during public press conferences (see: https://ktar.com/story/4598971/covid-19-exposure-notification-app-launched-in-arizona-never-reached-full-potential/). I ask that this data be provided in the smallest timeframes available—i.e., downloads per day are preferred; if not available, then downloads per week; if not available, then downloads per month.

2) Data documenting the number of exposure codes issued by the Arizona Covid Watch COVID-19 exposure app from the date the app was launched until the present. The Department has publicly disclosed the existence of his data to multiple media outlets and during public press conferences (see: https://ktar.com/story/4598971/covid-19-exposure-notification-app-launched-in-arizona-never-reached-full-potential/). I ask that this data be provided in the smallest timeframes available—i.e., downloads per day are preferred; if not available, then downloads per week; if not available, then downloads per month.

3) Aggregate analytics statistics from the Exposure Notifications Express (ENX) system—from the date the department began using the system until the present—for each of the metrics provided by the ENX system (see list below). Where possible, I ask that this data be provided in the smallest timeframes available—i.e., exposure notifications per day are preferred; if not available, then exposure notifications per week; if not available, then exposure notifications per month. For further explanations of the ENX metrics, please see: https://github.com/google/exposure-notifications-android/blob/master/doc/enexpress-analytics-faq.md.

ENX analytics metrics:
- "The number of exposure notifications sent in a public health authority’s region"
- "The number of user interactions (e.g., taps, dismissals) with exposure notifications in the region"
- "Histograms of the risk scores computed for users of the Exposure Notifications System in the region"
- "The number of exposure notifications sent in the past 14 days when verification codes are used in the region"
- "The number of exposure notifications sent in the past 14 days when temporary exposure keys are shared in the region"
- "Histograms of the number of days between having an exposure and receiving a notification"

Please note that the department and other participants in the Arizona Covid Watch program and Exposure Notifications Express program have certified that the data and aggregate analytics available through these systems are privacy preserving and cannot be used to re-identify individuals.

I ask that all fees be waived as I am a journalist and intend to use the requested records to publish articles in the public interest. In the event you choose to impose fees, I request a detailed breakdown of the fees, including the hourly wage of each employee involved and an explanation justifying the employee hours required to fulfill the request.

Should you choose to reject this request or redact portions of it, I ask that you provide a detailed breakdown of the statutory exemptions and associated case law underlying your decision to withhold each/any portions from public review.

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 10 business days.

Sincerely,

Todd Feathers
