A spokesman from Tinder, which launched in 2012 and is owned by Match Group, said: "Searchable information on Swipe Buster is public information that Tinder users have on their profiles. No private user information is being made public. If you want to see who's on Tinder we recommend saving your money and downloading the app for free."
Tinder also stressed that accounts are authenticated using public information from Facebook, which means that it is difficult to conceal your "identity or intentions".
Swipe Buster wasn't designed for snooping partners, but to highlight the privacy issues associated with oversharing online. The developers said they accessed the data in the same way as other third-party apps such as Tinderly and Bonfire for Tinder, apps that automatically like profiles to save users time swiping.
Tinder said it wasn't concerned about the privacy of its users and that you could find out if someone is using its service by downloading the app and swiping.
"We decided to show people an example of how much data about them is available, by answering one of the bigger questions in relationships, is he or she cheating on me?" said a spokesman from Swipe Buster.
"This is not a Tinder-specific issue. People have way too much information about themselves available publicly, and should be aware of the privacy settings on all the services they use. Hopefully this conversation will remind a significant amount of people of that."
HOW IT WORKS
To see if someone you know has been using Tinder recently all you need is $4.99 and their name, age, gender and location. You don't need your own Tinder account, but you do have to give Swipe Buster your email address so it can send you the results of your search.
Go to the Swipe Buster website.
Enter the person's first name as it appears on Facebook, their age and gender.
Predict where the person probably used Tinder last.
Swipe Buster asks users to "Be as accurate as possible" when entering this detail.
Then let the handy app do the rest of the work for you.
