Facebook managed to put its vast treasure trove of user data to good use after Friday’s tragic terror attacks in Paris: the social network customized its safety check feature to let users know whether their friends and loved ones in Paris are safe.
Users in the area are being alerted by Facebook’s mobile apps, asking them whether they are safe, and offering to check on any of their friends. The app has also been sending out alerts to anyone who has friends in Paris, and Facebook’s website lets anyone check on the status and whereabouts of their friends as well.
Most people have likely seen Facebook’s safety check for the first time today, but the company actually launched it in response to the Nepal earthquake earlier this year. At the time, Facebook CEO Mark Zuckerberg wrote: “When disasters happen, people need to know their loved ones are safe. It’s moments like this that being able to connect really matters.“
