Mozilla Rally is a program that allows you to donate your browsing data to help us understand the Web, how people interact with it, and how people use their browsers. Participation in Mozilla Rally is strictly voluntary. Once you’ve opted in, you will have the option to choose which studies to participate in and what data you want to share. These studies will collect varying information about your browsing behavior, possibly including what web pages you visit and how you interact with them.

We protect your privacy by ensuring the following:

• Your data will not be sold
• Your data will only be shared with the researchers you’ve agreed to share it with
• The data we collect from you is not connected to your name, email address, or IP, and you are only identified by a randomly generated number
• We don’t collect browsing information when you are in Private Browsing. If a future study requires collection of your data in Private Browsing mode, Mozilla Rally will let you know at the time of enrollment.
• Every time you join a study, you will be prompted to read its Privacy Consent Notice.

By participating in this group, you put your data to work for a better Internet. Our goal is to better understand topics like ethical AI, online privacy, algorithmic bias, discrimination, and misinformation. The data you agree to share with Mozilla (the makers of Firefox) helps create tools for better internet transparency and design products that give control back to the people who use them.
