UserSearch: This lets you search for a username on dating sites, letting you know if one has been found. The results are free, and they don’t need you to register. Cheatbuster: This only works for Tinder, but it’s supposedly got a 98% accuracy rating. Spokeo: This will pull up any social media sites associated with an email or name, but it can be tough to sift through the data if the person has a super common name, like John Williams. Socialcatfish: Like Spokeo, this will pull up any social media accounts and photos associated with a name. If you download one of these apps or programs and it asks if you want to access someone’s accounts, camera, or location data, do not use it. This kind of software is typically illegal.

Many sites allow you to sign in with a phone number. If their email doesn’t pop up, try their phone number instead. This will only tell you if someone ever had a profile. It won’t tell you if they’re actively using the dating site. If you’re looking into your partner and the two of you met on a specific dating site, this won’t help. Do this on as many dating sites and apps as possible. The most popular dating sites include Tinder, Match, OkCupid, Bumble, Hinge, and Zoosk.

If a website does send out an email or text, that person will get the email or text to reset their password. In other words, they’ll know someone tried to get into their account. Like the profile-making trick, this only tells you if the person ever had a profile. It doesn’t tell you if they’re actively using it now.

You can ask a friend already on the dating site to do this for you instead. If you do make your profile, be fair to folks on the site by mentioning you aren’t looking for anything in your profile. This is easier if you live in a less populated area. It will take a lot longer to get through many profiles if you live in a big city.

So, if you have a person in your life who uses “Maxine41” for everything, you might search, “Maxine41” site:tinder. com or ”Bumble. com/@Maxine41”

It’s unclear just how accurate this is. Many dating sites have privacy settings that may make sorting their images impossible, but this may work.

You might ask, “I don’t know if you’re comfortable with it, but I’d like to be open with one another regarding our social media and phone usage. Would you be okay with sharing?” If they ask why you want to do this, consider telling them the truth about why you’re nervous. If you aren’t ready for that conversation, you could tell them, “I just want to know we can trust each other. ”

Search for the major dating sites manually (i. e. search “Tinder,” “Bumble,” etc. ). If any results pop up, they’re browsing that site and probably have a profile. Depending on where you live, this may actually be illegal. Double-check the privacy laws where you live to see if you’re going to commit a crime before doing this.

If they’re actively hiding this from you, go into their settings and scan the “disabled apps” list. These apps on their phone have installed, but they’re hiding from the home screen and app list. This can be a crime depending on where you live. Make sure that you aren’t violating the law before you look through their phone.

they may be talking to someone they met outside of a dating app or website. If they’ve always been a bit possessive of their phone or they’re a bit of a social media addict and nothing has changed, don’t assume they’re hiding something from you.

You might say, “Hey, I’m not mad or anything, but I’ve been really nervous you’re using dating sites behind my back. Can we talk about it? It’s really making me upset. ” If you two haven’t had the “exclusive” conversation, they may simply think you two are still being casual. It’s unfair to snoop around if they don’t even know they’re supposed to delete the app or profile yet![13] X Research source
