The way Secret Crush works is pretty simple. You can select up to nine Facebook friends you want to express an interest in and then Facebook does its magic - from Facebook's announcement:
If your crush has opted into Facebook Dating, they will get a notification saying that someone has a crush on them. If your crush adds you to their Secret Crush list, it's a match! If your crush isn't on Dating, doesn't create a Secret Crush list, or doesn't put you on their list, no one will know that you've entered a friend's name.Wrong, Facebook will know. It's not like Facebook's algorithms can't already tell who you like already, based on your activity on Facebook and its other properties. But explicitly sharing your crushes with the company might be risky.
Facebook told Wired that Dating or Secret Crush data won't be used "to make content or advertising decisions."
This, however, is Facebook, and Facebook proved it couldn't be trusted before.
"All activity that occurs in FB Dating stays in FB Dating and will not be shared externally," a Facebook spokesperson said. But will it be shared internally?
Secret Crush isn't exactly a novel concept, and Tinder is based on a version of this. But Facebook has the huge advantage of backing this feature into its own app. Rather than swiping right and left on strangers, you're basically doing it with your friends.
