ProPublica crée un plugin Chrome pour savoir dans quelles catégories #Facebook vous range ►https://www.propublica.org/article/breaking-the-black-box-what-facebook-knows-about-you
We built a tool that works with the Chrome Web browser that lets you see what Facebook says it knows about you — you can rate the data for accuracy and you can send it to us, if you like. We will, of course, protect your privacy. We won’t collect any identifying details about you. And we won’t share your personal data with anyone.
This is the same information that Facebook itself offers users — buried deep in its site. (It’s in a section of its settings called “Ad Preferences.”) It’s not clear if this data represents all that Facebook knows about a person. For instance, we haven’t yet seen anyone with credit card or property ownership listed. Which is why we’re particularly interested in hearing what you found out.
You can help us examine whether what Facebook says it knows matches up with the #categories it sells.
