Price Comparison

Description

Expose how websites personalize prices to you.
The Price Comparison Tool by Volunteer Science enables you to see how corporations may be changing the prices you see based on factors like your browser cookies and user agent. Pages you visit on Amazon, Google Flights, Walmart, Home Depot, and Hotels.com will be loaded on a remote server, and the server's prices will be loaded seamlessly into your page so that you can compare them. That's pretty cool, but the best part is that you'll be helping data scientists understand this phenomenon, called "price personalization".

When you download the plugin, we ask to access your browsing history and cookies. However, we will not collect this data unless you explicitly donate it to us in the “Manage” tab in the plugin’s options. We do collect data from the results of your searches. You can opt out of this through the “Manage” tab as well. By downloading this plugin, you agree that you are over 18 years old and have read and agree to our terms of service, which may be found here: http://bit.ly/2hkUpSR.

The personalization data generated by this plugin can be used in a research study to understand online personalization. By downloading this plugin, you acknowledge the terms of service (http://bit.ly/2hkUpSR).
