Xray – User data and browsing

a new tool that reveals which data in a web account, such as emails, searches, or viewed products, are being used to target which outputs, such as ads, recommended products, or prices. It can increase end-user awareness about what the services they use do with their data, and it can enable auditors and watchdogs with the necessary tools to keep the Web in check.
