This Facebook page has been made publicly accessible and now contains everything you visit and watch online.
After promising us more transparency into how user data is collected and used, Facebook has finally launched a tool that they say will “give us more control over our data.” It’s called Off-Facebook Activity, and it’s basically what it says: a sample of everything Facebook collects about our web activity outside of its services.
While the tool has its own website, going into the new Facebook settings gives you access to it, where you can go directly to this link, and there you will find your web activity.
On this page, you will find all the information held by companies and organizations that share data with Facebook. This includes all kinds of interactions we have with apps, pages, or web services that are not part of Facebook but also send data about what you do to Facebook.
The point is that practically everything you visit, click, purchase, and read online ends up in Facebook's hands. The company says it uses this information to “personalize your experience” and do things like “show relevant ads.”
Facebook says it doesn’t sell your information to anyone and that it prohibits companies or organizations from sharing confidential information with them, such as passwords, health, or financial information. Although it doesn’t say that this has never happened.
