As you might have heard, personal data of more than 500 millions Facebook users leaked in 2019. Name, address, relationship status, mail and mostly importantly phone number. Mauritius is in there with 848,558 user profiles.
I made a tool to check whether your Facebook data has been leaked. Just type your phone number and it will check from a copy of the database which I acquired whether it's in there. If so, it will display the information about you that is out in the wild.
