In a blog posted on Facebook, Zuckerberg explained the changes, which make it easier for users to choose how their information, pictures and preferences are shared publicly, as well as enabling them to switch off third-party applications.
Earlier this week, Zuckerberg defended the site from accusations that it was cavalier with users' data, but admitted that "sometimes we move too fast – and after listening to recent concerns, we're responding".
In recent months, Facebook has been condemned by the media and online communities for its use of personal data – there were even accusations that Facebook had been sharing personal data with advertisers. Zuckerberg vociferously denied this.
He said: "Advertisers may target ads to people according to certain demographics, but they receive only anonymous data reports. We don't share your personal information with our advertisers."
