Usable Privacy Choices Research
We are conducting research on ways to make privacy choices easier for consumers to find and exercise. See also our work with the Usable Privacy Policy Project.
News
- On March 15, 2021 the California AG announced approval of additional regulations including the use of our "Privacy Options" icon
- On December 10, 2020 the California AG issued
a notice of fourth set of modifications of CCPA and recommended
adoption of the
blue stylized togle icon designed and tested by our group! You
can download the icon in several
sizes
- May 28, 2020: We conducted a study to evaluate four candidate CCPA icons at the request of the California AG
- March 11, 2020: The California AG's latest proposed CCPA regulations eliminate the opt-out button completely (see also the Cal AG's CCPA regulation website)
- February 24, 2020: We conducted a followup study to evaluate the California AG's proposed opt-out button and submitted a report, finding the AG's proposed button may mislead consumers
- February 4, 2020: We submitted a report to the California Attorney General's office based on our research with recommendations for a CCPA opt-out button
