The free third-party program is built on Grindr's Private API, which gives it access to the gay computer software database. It uses a technique called "trilateration" to find users so that anyone who has access to it can follow people around while walking. All you need to do to find users nearby is to use Fuck's filters, which can restrict people based on their ethnicity, relationship, and other data. Yes, because the app can tap into Grindr's database, it can reveal not only the user's locations, but also their image, body type, ethnicity, HIV status, latest HIV test, and even their sexual status.

It's easy to see how the app can be used as a tool for harassment and how it can expose users to homophobic violence. Especially since Grindr still makes it possible to find men in countries where LGBTQ + persons are not accepted. While it is true that the company blocked placement tracking in Russia, Nigeria, Egypt, Iraq and Saudi Arabia, it can still track in countries like Algeria, Turkey, Belarus, Ethiopia, Qatar, Abu Dhabi, Oman, Azerbaijan, China, Malaysia and Indonesia . .
BuzzFeed News states that GitHub has already disabled public access to Fuckr – it hosted the app's depot – but there are still many modified versions that can do the same as floating around. The company did not respond to the publication's request for a clarification of how Fuckr gained access to its private API. Like BuzzFeed however, many things point out that Grindr can do to prevent third parties from accessing the database, such as implementing a more powerful way to hide their precise placement tracking. For now, users can turn off the phone's location services (or turn it off for Grindr, especially) to protect themselves.
