While you as a user normally browse the internet it works in the background and helps you identify what sensitive information(PII—Name, Date Of Birth, Email, Passwords, Passport number, Auth tokens.) are being shared/leaked to which all third-parties and by which all websites.

The issues that Local Sheriff helps identify:

• What sensitive information with is being shared this which parties?
• What companies are behind these third parties?
• What can they doing with this information? EG: de-anonymize users on the internet, create shadow profiles.
• Local Sheriff can also be used by organizations to audit:

Which all the third-parties that are being used on their websites. The third-parties on the websites are implemented in a way that respect user’s privacy and sensitive data is not being leaked to them. Local Sheriff is a web-extension that can used with Chrome, Opera, Firefox.
