If I create a tinder profile with Facebook, will my friends and family know that I’m on Tinder?
Indeed, Tinder is a dating app and basically, its never post your profile on the Facebook account right now. Currently, it is not possible to see whether a Facebook account is also linked to Tinder. You should go to the Apps and Websites tab in your Facebook settings and adjust the Tinder function to "only me" so if you are feeling suspicious, you should go to the Apps and Websites section.
