In news guaranteed to delight obsessive exs everywhere (not to mention anyone looking to indulge serious stalker tendencies),  there's now a sure-fire way to find out if the one you love is using Tinder on the sly - and it only costs $6.

Where once you would have to go down the costly road of hiring a private investigator (sounds crazy, but people go there), now you can simply log onto the new (and very appropriately named) website Swipe Buster to uncover your lover's infidelities for yourself.

Given that a scary 30 per cent of Tinder users are married, according to a survey conducted last year, and only 54 per cent would actually consider themselves single, this is one new website that people are going to lose some sleep over. All you need to know is the first name, age and location of your suspect and Swipebuster will search Tinder's database for users matching your search terms.  You can even find out when they last used the dating app.

If it sounds like a breach of privacy, it isn't - you sign up to have your details stored and accessible in Tinder's terms and conditions. The founder of Swipebuster, who has chosen to remain anonymous, told Vanity Fair that he established the website in part to draw attention to this prolific data overshare. "There is too much data about people that people themselves don't know is available," he said. "Companies are also not doing enough to let people know they're doing it."

Whoever he is, we're not sure we buy into the Swipebuster founder's so-called motivations - more likely, he's been the victim of a case of Tinder cheating himself.
