Is Grindr still free?
Grindr (/ˈɡraɪndər/) is a location-based social networking and online dating application for gay, bi, trans, and queer people. It is available on iOS and Android devices in both free and premium versions (the latter called Grindr XTRA and Grindr Unlimited).
Can people on Grindr see your address?
(Most Grindr users do show their faces, but not their name.) But even then, Hoang points out that continually tracking someones location can often reveal their identity based on their address or workplace.
