There are many ways a person can catch a cheating spouse or significant other — like checking their social media following, reading their text messages, scrolling through their Venmo transaction history and so on.
However, according to a private investigator — there is one unexpected app that most people would never think to check if their loved one is being sneaky behind their back.
London-based private investigator Aaron Bond said if someone is suspicious of any naughty business going on in their relationship — check their supermarket loyalty apps, the ones that help shoppers save money and earn rewards.
What does a receipt for buying eggs and toilet paper have to do with infidelity?
“While most people think of text messaging and call logs as the obvious signs of cheating, there are often other signs that can uncover and paint a larger picture,” Bond told the Mirror.
He said a supermarket loyalty member app can reveal a lot.
“Clubcard data is limited, but it does tell you a date and location, which is easily accessible if you log into your account,” he told the outlet.
“If your partner claims they were working or out with friends but the account shows they made a purchase in a completely different area, then it’s a clear red flag.”
This is just one of many tech red flags to be on the lookout for if you think the other person is cheating in your relationship.
If your significant other constantly conceals their phone — especially when notifications pop up, that’s not a good sign.
“Notifications can also reveal cheaters, so it’s common to switch them off or hide them if you’re doing something you don’t want your significant other to see,” radio show host, Kim Komando told the Daily Mail.
Clearing their search history on apps and closing tabs on Safari or Chrome are other big red flags for cheating.
“If they routinely access dating sites, secret email accounts or anything, they will probably think to cover their tracks,” Komando said.
A person’s location history is another tell-tale sign that can reveal if they’re being unfaithful.
Komando said to check this on your partner’s phone — if you can — to see if there’s one place in particular they frequent often.
