The technology developed by Cambridge Analytica and its affiliate SCL was used for several political campaigns, among them Trump's and Ted Cruz's presidential runs, as well as the Brexit campaign in the UK.
The app, created in November 2013, asked users for permission to access their profile information - and also that of their friends'.
A whistleblower who worked at Cambridge Analytica spoke to The Guardian, claiming that he worked with Mr Kogan "to harvest millions of people's profiles".
The 270,000 people who downloaded the app allowed it access not only to their data, but some of their friends'-depending on their settings.
Not only this, after getting feedback from the Facebook community, Facebook made a decision to hand the leash of personal information outlay and friend list of exclusively to the users so that they can "control their experience" themselves, as stated on the post.
It said none of that data was used in the services it provided to Mr Trump's campaign. In a statement Friday, Facebook VP and General Counsel Paul Grewal said the social network is suspending Cambridge Analytica while the social network investigates reports that the data wasn't destroyed.
Late Friday night, Facebook announced that it's suspending Strategic Communication Laboratories (SCL) from its platform. "We will take legal action if necessary to hold them responsible and accountable for any unlawful behavior".

The letter arrived just a few days before Stephen K. Bannon, a part owner of Cambridge Analytica and former vice president of the company's board, signed on as Trump's campaign manager.
He said that "no data from GSR was used by Cambridge Analytica as part of the services it provided to the Donald Trump 2016 presidential campaign".
Furthermore, the perception that Facebook got hoodwinked in this manner hurts its reputation in terms of vetting interested parties who want to use Facebook.
With its suspension of policy violators and its steady protective measures to uphold the safety of user experience on its platform, Facebook proves why it continues to be a favorite among the social network users.
The New York Times meanwhile reported that copies of the data harvested for Cambridge Analytica were still online and that its team had viewed some of the raw data. It says it has data on 220 million Americans, two-thirds of the USA population.
"In 2015, we learned that".
The British probe is part of a broader inquiry into how political parties, data companies and social media platforms use personal information to target voters during political campaigns, including Britain's 2016 Brexit referendum on European Union membership.
Wylie also commented on the implications of this practice could have for the future.
