The California Public Utilities Commission (CPUC) contracted with California State University, Chico (CSU Chico) and subcontracted with California State University, Monterey Bay (CSUMB) to develop a web-based tool, the CalSPEED web app, to collect broadband measurements in real‐world conditions using Ookla’s Speedtest Custom product.
The CPUC is committed to promoting and protecting the privacy rights of individuals, as enumerated in Article 1 of the Constitution of the State of California, the Information Practices Act of 1977, and other state and federal laws.
It is the policy of the CPUC to limit the collection and safeguard the privacy of personal information collected or maintained by the web app. The information management practices used in conjunction with this web app conform to the requirements of the Information Practices Act (Civ. Code § 1798 et seq.), the Public Records Act (Govt. Code § 6250 et seq.), Government Code sections 11015.5 and 11019.9, and other applicable laws pertaining to information privacy. The use and development of the CalSPEED web app and collection of data are authorized under the California Public Utilities Code (Pub. Util. Code) Section 281.
The information the CalSPEED web app collects is limited to information used to measure and analyze the performance of your Internet (including Wi-Fi-enabled) service. As a part of this collection, the CPUC and CSUMB will collect, store, and share with the public the following information:
