Facebook's revenue depends on targeted advertising, which involves analyzing user data to decide which ads to show each user. Facebook buys data from third parties, gathered from both online and offline sources, to supplement its own data on users. Facebook maintains that it does not share data used for targeted advertising with the advertisers themselves.<ref>{{Cite news|title="What Facebook's privacy policy allows may surprise you"|last1=Ortutay|first1=Barbare|date=March 25, 2018|url=https://www.chicagotribune.com/business/ct-facebook-privacy-policy-20180325-story.html}}</ref> The company states: <blockquote>"We provide advertisers with reports about the kinds of people seeing their ads and how their ads are performing, but we don't share information that personally identifies you (information such as your name or email address that by itself can be used to contact you or identifies who you are) unless you give us permission. For example, we provide general demographic and interest information to advertisers (for example, that an ad was seen by a woman between the ages of 25 and 34 who lives in Madrid and likes software engineering) to help them better understand their audience. We also confirm which Facebook ads led you to make a purchase or take an action with an advertiser."<ref name="Data Policy" /></blockquote> {{As of|October 2021}}, Facebook claims it uses the following policy for sharing user data with third parties: <blockquote>Apps, websites, and third-party integrations on or using our Products. When you choose to use third-party apps, websites, or other services that use, or are integrated with, our Products, they can receive information about what you post or share. For example, when you play a game with your Facebook friends or use a Facebook Comment or Share button on a website, the game developer or website can receive information about your activities in the game or receive a comment or link that you share from the website on Facebook. Also, when you download or use such third-party services, they can access your public profile on Facebook, and any information that you share with them. Apps and websites you use may receive your list of Facebook friends if you choose to share it with them. But apps and websites you use will not be able to receive any other information about your Facebook friends from you, or information about any of your Instagram followers (although your friends and followers may, of course, choose to share this information themselves). Information collected by these third-party services is subject to their own terms and policies, not this one. Devices and operating systems providing native versions of Facebook and Instagram (i.e. where we have not developed our own first-party apps) will have access to all information you choose to share with them, including information your friends share with you, so they can provide our core functionality to you. Note: We are in the process of restricting developers' data access even further to help prevent abuse. For example, we will remove developers' access to your Facebook and Instagram data if you haven't used their app in 3 months, and we are changing Login, so that in the next version, we will reduce the data that an app can request without app review to include only name, Instagram username and bio, profile photo and email address. Requesting any other data will require our approval.<ref name="Data Policy" /></blockquote> Facebook will also share data with [[law enforcement]] if needed to.<ref name="Data Policy" /> Facebook's policies have changed repeatedly since the service's debut, amid a series of controversies covering everything from how well it secures user data, to what extent it allows users to control access, to the kinds of access given to third parties, including businesses, political campaigns and governments. These facilities vary according to country, as some nations require the company to make data available (and limit access to services), while the European Union's [[General Data Protection Regulation|GDPR]] regulation mandates additional privacy protections.<ref name=wsj15>{{Cite news|url=https://www.wsj.com/articles/facebooks-timeline-15-years-in-11549276201|title=Facebook's Timeline: 15 Years In|last1=Wilberding|first1=Kurt|date=February 4, 2019|work=[[The Wall Street Journal]]|access-date=February 6, 2019|last2=Wells|first2=Georgia|issn=0099-9660}}</ref> Summary: Please note that all contributions to Christianpedia may be edited, altered, or removed by other contributors.
