The page was created by the company Supremo to raise awareness among users of the social network about personal data that can be exposed without due knowledge or memory.
It contains information such as the last place you visited, the people you are related to, the educational institutions you attended, where you worked and a random photo that has been shared publicly.
To use Supremo’s online tool, you must grant access to your Facebook data. In its privacy policy, the page says to remove all user information from its records.
The purpose of the site is to get people to clean up Facebook and remove sensitive data. Supremo encourages users to think before posting something publicly on Facebook, asking a simple question: would I put this on a billboard for everyone to read? If the answer is no, the ideal is not to share it publicly.
Facebook offers options to restrict your posts to your friends or even a selection of contacts on the social network.
