As of Monday, Facebook Graph Search has officially opened its big, omniscient arms to every last check-in, status update, note, and comment you’ve ever posted throughout your entire Facebook career. Which, yes, sounds pretty terrifying, but don’t worry—we’re here to help you cover your tracks. Thankfully, Facebook has given us the tools we need to (mostly) take control of our privacy moving forward. Here’s what you need to know. The main concern with Facebook’s new, more granular search is that your hundreds—and in some cases thousands—of past posts, each now requires its own, unique privacy setting. But don’t worry, you’re not going to have to spend days clicking through every embarrassing, insipid post from the previous 7-odd years. Instead, Facebook lets you change your entire past en masse—sort of.
