This is how they are able to gather information:
1- Social plugins
2- Facebook login
3- Facebook Analytics
4- Facebook ads and measurement tools
When a user gets logged in on another website or an app through Facebook, the social platform is informed about it even if a user logs out. It indicates that Facebook still manages to collect the information of a user from a lot of different places. It is pertinent to state that Facebook’s reach is quite hard to avoid.
According to David Baser, Facebook also gathers the information through:
1- Computer IP address
2- Type of browser
3- Type of software
4- Other relevant material
David affirmed that Facebook doesn’t sell any data. Instead, it utilizes the information to better cater the needs of an individual.
