In an effort to avoid mistake information, Facebook has developed a system to evaluate users credibility.

Facebook has removed its Onavo Protect security app from Apple App Store because the program violated the smartphone maker's privacy policy against collecting user data.

The App, Created by an Israeli Startup Facebook purchased five years ago, allows users to connect to a virtual private network that keeps your browsing identity anonymous – a smart workout on free public W-Fi – by routing through a third party server.

However, Onavo Protect also collects data on websites and apps, a concern for consumers and online players as Facebook continues to recover from the Cambridge Analytica scandal, where 87 million Facebook users had unconscious personal data sold to a political targeting company.

Facebook removed the Onavo app from the App Store on Wednesday, but it is still available in the Google Play Store.

"We've always been ready when people download Onavo about the information that is collected and how it is used," Facebook said in a statement. "As a developer on Apple's platform, we follow the rules they've put in place."

Some changes to Apple's business lines, as updated two months ago, elevated apps use user data beyond what is required for the app itself.

"We are working hard to protect the user's privacy and data security through the Apple ecosystem," Apple said in a statement on the Onavo situation. "With the latest update to our policies, we made it clear that apps should not collect information about other apps installed on a user's device for the purpose of analyzing or advertising / promoting, and clarifying which user data should be collected and how it will be used. "

Data from Onavos app has helped Facebook identify potential new product areas. It was able to track the user interest in Snapchat's Stories feature before Facebook introduced its own Stories feature on Instagram, as it also owns, The Wall Street Journal reported last year. Onavo data also supported Facebook's 2014 acquisition of WhatsApp for $ 22 billion, says Journal.

The removal of the app is the latest consequence of the Cambridge Analytica crisis and a Russian disinformation operation on the social network, both of which occurred during More: More: Facebook: Political campaign campaigns originating in Iran, Russia in front of American Midways

Five months ago, Facebook was aware that knew that the UK political consulting firm had received personal information from hundreds of thousands of users who downloaded a personality profile. The app's developer then passed the information, and details of his Facebook friends, to Cambridge Analytica without the user's knowledge, said the company.

Finally, the number of potentially affected users grew to 87 million and it was discovered that Cambridge Analytica claimed the British firm helped Donald Trump win the presidential election. The Trump campaign has said that it did not use data from Cambridge Analytica.

Facebook is now trying to trust its United States mid-term election platform after a Russian disinformation campaign that increased near the end of the 2016 constituency and involved millions of false posts on the social network.

Special Council Robert Mueller issued charges in February of 13 Russian citizens and three units, including the Kremlin-called Internet Research Agency for the use of Facebook and other social media networks, to try to influence presidential elections in 2016.

These events led to CEO Mark Zuckerberg to perform performances in front of the House and the Senate, as well as the European Parliament.

Legislators picked up Onavo during a senate debate in April, and it is a topic among those on more than 400 pages with answers sent by Facebook.

When users use the Onavo VPN feature, Onavo receives mobile data traffic. This helps us improve and operate the Onavo service. Because we are part of Facebook, we also use this information to improve Facebook products and services, the answer says.

"We let people know about this activity and other ways that Onavo uses, analyzes and shares data (such as apps installed on user devices) in App Store descriptions and when they first open the application after downloading it," the answer continues. "Facebook does not use Onavo data for use of Facebook products, nor does it add any Onavo data or data about individuals app usage to Facebook accounts."

Facebook also said this week that it banned an app called myPersonality from the social network. Facebook will notify the 4 million people who shared their information with the app, which was active primarily before 2012, the company said in a blog post.

In general, Facebook has suspended more than 400 apps as part of its review of
