This extension allows you to navigate how FB collects your data
This extension only collects the categories Facebook has placed you in. We do not tie those categories to any identifiable information, including cookies. For example, if you have “Surfing” as an interest and share that with ProPublica, no identifiable information is sent. The information you share is only the name of the category, the I.D. number Facebook gives it internally, some other subcategories and your logged reaction to the category.
When that information is received by our server, it pays no attention to where it's coming from. It only checks to see if that category has been logged. If it hasn’t, it’ll add that category to the database. If it has, it will check to see if there were any updates in reaction count. We also have no cookies on the requests to track users.
